In most social species, position in the male social hierarchy and reproductive success are positively correlated; in humans, however, this relationship is less clear, with studies of traditional societies yielding mixed results. In the most economically advanced human populations, the adaptiveness of status vanishes altogether; social status and fertility are uncorrelated. These findings have been interpreted to suggest that evolutionary principles may not be appropriate for the explanation of human behavior, especially in modern environments. The present study tests (...) the adaptiveness of social status with actual mating and reproductive data in a representative sample of males from an industrial society. Reproductive success, even when assessed by a more reliable measure ofactualmale fertility than the one commonly used, fails to correlate with social status. In striking contrast, however, status is found to be highly correlated withpotentialfertility, as estimated from copulation frequency. Status thus accounts for as much as 62% of the variance in thisproximatecomponent of fitness. This pattern is remarkably similar to what is found in many traditional societies and would result in a substantial positive relationship between cultural and reproductive success in industrial populations were it not for the novel conditions imposed by contraception and monogamy. Various underlying mechanisms are suggested for these findings, illustrating the value of current behavioral and reproductive data in the study of adaptation. It is concluded that evolutionary explanations of human behavior remain entirely relevant in modern societies. (shrink)

Two recent studies have shown a relationship between male height and number of offspring in contemporary developed-world populations. One of them argues as a result that directional selection for male tallness is both positive and unconstrained. This paper uses data from a large and socially representative national cohort of men who were born in Britain in March 1958. Taller men were less likely to be childless than shorter ones. They did not have a greater mean number of children. If anything, (...) the pattern was the reverse, since men from higher socioeconomic groups tended to be taller and also to have smaller families. However, clear evidence was found that men who were taller than average were more likely to find a long-term partner, and also more likely to have several different long-term partners. This confirms the finding that tall men are considered more attractive and suggests that, in a noncontracepting environment, they would have more children. There is also evidence of stabilizing selection, since extremely tall men had an excess of health problems and an increased likelihood of childlessness. The conclusion is that male tallness has been selected for in recent human evolution but has been constrained by developmental factors and stabilizing selection on the extremely tall. (shrink)

In Western societies, height is positively correlated with reproductive success (RS) for men but negatively correlated with RS for women. These relationships have been attributed to sexual selection: women prefer tall men, and men prefer short women. It is this success in the marriage market which leads to higher RS for tall men and short women. We have already shown that the relationship between height and RS for women is quite different in a non-Western context. In a (...) subsistence farming community in rural Gambia, height is positively correlated with reproductive success for women, largely owing to the higher survival of the children of tall women. Here, the relationship between height and reproductive success is analyzed for men in the same community. For these Gambian men, there is no significant relationship between height and the number of children they produce, although tall men do contract more marriages than shorter men. We conclude that environmental context needs to be taken into account when analyzing human reproductive behavior. (shrink)

Although many aspects of human cognition are likely to be passively affiliated with the primary impetus for hominid brain expansion during the Plio-Pleistocene, that expansion was most likely generated and maintained not by functions but by improved capacities of reproductive success, especially survivorship.

The wealthy elite males of nineteenth-century Krummhörn (Ostfriesland, Germany) achieved an above-average reproductive success. Membership in the elite class was determined from a list of the 300 richest men in the Ostfriesland district compiled by authorities in 1812. The main components establishing the link between cultural success and reproductive success aredifferences in the number of offspring owing to differences both in time spent in fecund marriage (mating success) and in rate of reproduction;differences in the (...) probabilities of one’s adult offspring marrying locally vs. emigrating unmarried owing to differential ability to allocate resources that enhance the “social placement” of adult offspring; anddifferences in the probability of total reproductive failure (lineage extinction).Contrary to what might be expected, infant survivorship was lowest amongst the richest families. We conclude that to a great extent females’ reproductive decisions contribute to the greater reproductive success of the elite males. (shrink)

The fundamental postulate of sociobiology is that individuals exploit favorable environments to increase their genetic representation in the next generation. The data on fertility differentials among contemporary humans are not cotvietent with this postulate. Given the importance ofHomo sapiensas an animal species in the natural world today, these data constitute particularly challenging and interesting problem for both human sociobiology and sociobiology as a whole.The first part of this paper reviews the evidence showing an inverse relationship between reproductive fitness and (...) “endowment” in contemporary, urbanized societies. It is shown that a positive relationship is observed only for those cohorts who bore their children during a unique period of rising fertility, 1935–1960, and that these cohorts are most often cited by sociobiologists as supporting the central postulate of sociobiology. Cohorts preceding and following these show the characteristic inverse relationship between endowment and fertility. The second section reviews the existing so-ciobiological models of this inverse relationship, namely, those of Barkow, Burley, and Irons, as well as more informal responses among sociobiologists to the persistent violation of sociobiology's central postulate, such as those of Alexander and Dawkins. The third section asks whether the goals of sociobiology, given the violation of its fundamental postulate by contemporary human societies, might not be better thought of as applied rather than descriptive, with respect to these societies. A proper answer to this question begins with the measurement of the pace and direction of natural selection within modern human populations, as compared to other sources of change. The vast preponderance of the shifts in human trait distributions, including the IQ distribution, appears to be due to environmental rather than genetic change. However, there remains the question of just how elastic these distributions are in the absence of reinforcing genetic change. (shrink)

Sober develops an account of adaptations on which they must have been positive causal factors for reproductive success. Glymour defends an account of a proper subset of adaptations—adaptations to particular environmental conditions—on which traits must interact in a special way with adapting conditions to cause reproductive success. These theories render conflicting judgments about which traits count as adaptations in some interesting cases. In this article I explore one such case and argue that we ought to replace (...) the notion of adaptation qua positive causal factor with a novel notion of adaptation. (shrink)

Data support the claim from the target article that women, both cross-culturally and historically, have employed a variety of mating strategies, marrying but also engaging in short-term unions. But those strategies appear to be practiced simultaneously and not conditionally as Gangestad & Simpson propose, a finding consistent with assumed constraints on the potential reproductive success of females.

Anecdotal evidence from many hunter-gatherer societies suggests that successful hunters experience higher prestige and greater reproductive success. Detailed quantitative data on these patterns are now available for five widely dispersed cases (Ache, Hadza, !Kung, Lamalera, and Meriam) and indicate that better hunters exhibit higher age-corrected reproductive success than other men in their social group. Leading explanations to account for this pattern are: (1) direct provisioning of hunters’ wives and offspring, (2) dyadic reciprocity, (3) indirect reciprocity, (4) (...) costly signaling, and (5) phenotypic correlation. I examine the qualitative and quantitative evidence bearing on these explanations and conclude that although none can be definitively rejected, extensive and apparently unconditional sharing of large game somewhat weakens the first three explanations. The costly signaling explanation has support in some cases, although the exact nature of the benefits gained from mating or allying with or deferring to better hunters needs further study. (shrink)

Identifying the determinants of reproductive success in small-scale societies is critical for understanding how natural selection has shaped human evolution and behavior. The available evidence suggests that status-accruing behaviors such as hunting and prosociality are pathways to reproductive success, but social egalitarianism may diminish this pathway. Here we introduce a mixed longitudinal/cross-sectional dataset based on 45 years of research with the Batek, a population of egalitarian rain forest hunter-gatherers in Peninsular Malaysia, and use it to test (...) the effects of four predictors of lifetime reproductive success: foraging return rate, sharing proclivity, cooperative foraging tendency, and kin presence. We found that none of these factors can explain variation in lifetime reproduction among males or females. We suggest that social egalitarianism, combined with strikingly low infant and juvenile mortality rates, can mediate the pathway between foraging, status-accruing behavior, and reproductive success. Our approach advocates for greater theoretical and empirical attention to quantitative social network measures, female foraging, and fitness outcomes. (shrink)

Campbell's target article is a stimulating attempt to extend our understanding of sex differences in risk-taking behaviors. However, Campbell does not succeed in demonstrating that her account adds explanatory power to those (e.g., Daly & Wilson 1994) previously proposed. In particular, little effort was made to explore the causal links between survival (staying alive) and reproduction.

The target article effectively assesses multiple hypotheses for human sexuality, demonstrating support for a complex, integrated perspective. However, care must be taken when extrapolating human universal patterns from specific cultural subsets without appropriate ethnographic contexts. Although it makes a strong contribution to the investigation of human sexuality, the basal reliance on a reductionist perspective constrains the full efficacy of this research.

This paper scrutinises the many ways in which ‘success’ is portrayed in representing assisted reproductive technology (ART) services and illuminates how these definitions differ from those held by participant couples. A qualitative approach informed by feminist perspectives guided this study and aimed to problematise the concept of ‘success’ by examining literature from ART clinics, government reports on ART, and by analysing narratives of couples who have accessed ART services. As many ART services have varying definitions of ‘ (...) class='Hi'>success’ and as statistics are manipulated to promote further patronage of ART services, the likelihood of ‘success’ is often overstated. This paper is concerned with the effects this promotion has on the participants. We suggest that this very mobilisation of statistical success changes the ability of those who access ART services to make productive decisions about themselves inside these treatment regimes, as the basis for decision‐making is hidden by the way numbers, objectivity and clinical reasoning operate to maintain participation in the program. In such an operation, the powerful mix of hope and technology kept participants enrolled far longer than they originally planned. Moreover, how success rates are manipulated raises ethical issues for all involved: clients, counsellors, and nursing and medical professionals. (shrink)

Studies of the association between wealth and fertility in industrial populations have a rich history in the evolutionary literature, and they have been used to argue both for and against a behavioral ecological approach to explaining human variability. We consider that there are strong arguments in favor of measuring fertility (and proxies thereof) in industrial populations, not least because of the wide availability of large-scale secondary databases. Such data sources bring challenges as well as advantages, however. The purpose of this (...) article is to illustrate these by examining the association between wealth and reproductive success in the United States, using the National Longitudinal Study of Youth 1979. We conduct a broad-based exploratory analysis of the relationship between wealth and fertility, employing both cross-sectional and longitudinal approaches, and multiple measures of both wealth (income and net worth) and fertility (lifetime reproductive success and transitions to first, second and third births). We highlight the kinds of decisions that have to be made regarding sample selection, along with the selection and construction of explanatory variables and control measures. Based on our analyses, we find a positive effect of both income and net worth on fertility for men, which is more pronounced for white men and for transitions to first and second births. Income tends to have a negative effect on fertility for women, while net worth is more likely to positively predict fertility. Different reproductive strategies among different groups within the same population highlight the complexity of the reproductive ecology of industrial societies. These results differ in a number of respects from other analyses using the same database. We suggest this reflects the impossibility of producing a definitive analysis, rather than a failure to identify the “correct” analytical strategy. Finally, we discuss how these findings inform us about (mal)adaptive decision-making. (shrink)

An explanation of the inter-gender difference in longevity consistent with the 'disposable soma' theory of ageing is proposed. It is based on the concept of r-K selection as applied to the inter-gender situation. The concept predicts that the gender with a higher potential reproductive rate (males) should invest relatively less in somatic maintenance, which in its turn should result in a lower longevity according to the 'disposable soma' theory of ageing. In females, which are interpreted as K-selected organisms, the (...) reproductive strategy strongly depends on steady, secure constitution designed for oocyte/embryo bearing and is therefore closely related to somatic maintenance, whereas in (r-selected) males it has a greater behavioural component - risky, variable, with a greater potential reproductive success at the expense of somatic maintenance. The higher metabolic and growth rates, a higher premature mortality and a longer period of sexual competence of males also find explanation as a complex of r-selected traits. (shrink)

Patterns of three variables of reproductive strategies in male New World primates are examined: (i) how males obtain access to potential mates; (ii) how males obtain actual mating opportunities; and (iii) how males affect infant survival and female reproductive success. Male opportunities to associate with females, whether by remaining in their natal groups, dispersing and forming new groups, or dispersing and taking over or joining established groups, are strongly influenced by local population densities and correlate with female (...) reproductive rates and the extent of female reproductive seasonality and synchrony. Differences in male mating success are affected by female accessibility, whether male-male and male-female relationships are hierarchical or egalitarian, and whether female reproduction is seasonally restricted. Patterns of male behavior toward infants, characterized as active assistance, overt interference, or benign tolerance, appear to co-vary with differences in the degree to which males can affect female reproductive rates.These qualitative analyses suggest that the reproductive strategies of male New World primates can be classified along a continuum ranging from conservative to daring depending on whether female reproductive rates are relatively slow or fast and whether reproduction is strongly or weakly linked to seasonal ecological variables. Males adopt the conservative strategy of staying in their natal groups, forfeiting exclusive mating opportunities, and treating infants with tolerance when female reproduction is constrained by ecological factors. Conversely, males adopt the more daring strategy of dispersing and competing when potential payoffs through their ability to affect female reproduction are high. (shrink)

The authors propose that many morbidities higher in women than men are adaptations protecting survival, selected because survival has been especially crucial to mothers' reproductive success. Following their lead, I pursue variation in tradeoffs between reproduction and survival recognized by Darwin that were likely central to the evolution of many traits that distinguish us from our great ape cousins.

In Nigeria, reproduction is highly valued, with many people desiring to produce a child ‘in their own image and likeness’. Previously, aspiring parents often resorted to adoption. Today, the availability of assisted reproductive technologies (ARTs) has provided options other than adoption for those desiring to procreate. Through ARTs, aspirations for a family may be attained through an exchange of reproductive goods and services, and not necessarily through traditional heterosexual relationships. ARTs have altered the perception of parenthood as it (...) exists in Nigeria, and courts face a difficult task in defining parenthood within Nigerian jurisprudence, as they can only adjudicate based on extant law. Although ARTs provide greater individual choices for fulfilling the desire to procreate, they raise a number of ethical and legal issues that evolving legal systems, such as that in Nigeria, are ill‐equipped to manage. This paper describes the traditional assignment of parenthood under indigenous laws and other sources of law within the Nigerian jurisprudence. We carried out an in‐depth study of the Nigerian legislative framework and found that there are no laws directly regulating parenthood, procreation and ARTs in Nigeria. We also found that the extant laws are only tangentially related and do not answer the relevant questions sufficiently well, especially concerning succession, nationality and assignment of responsibility in collaborative reproduction. We conclude by highlighting the need for and recommending a regulatory framework on ARTs with a particular focus on providing a definition for parenthood achieved through ARTs in Nigeria. (shrink)

As a neo-liberal economy, India has become one of the new health tourism destinations, with commercial gestational surrogacy as an expanding market. Yet the Indian Assisted Reproductive Technology Bill has been pending for five years, and the guidelines issued by the Indian Council of Medical Research are somewhat vague and contradictory, resulting in self-regulated practices of fertility clinics. This paper broadly looks at clinical ethics in reproduction in the practice of surrogacy and decision-making in various procedures. Through empirical research (...) in New Delhi, the capital of India, from December 2011 to November 2012, issues of decision-making on embryo transfer, fetal reduction, and mode of delivery were identified. Interviews were carried out with doctors in eighteen ART clinics, agents from four agencies, and fourteen surrogates. In aiming to fulfil the commissioning parents’ demands, doctors were willing to go to the greatest extent possible in their medical practice. Autonomy and decision-making regarding choice of the number of embryos to transfer and the mode of delivery lay neither with commissioning parents nor surrogate mothers but mostly with doctors. In order to ensure higher success rates, surrogates faced the risk of multiple pregnancy and fetal reduction with little information regarding the risks involved. In the globalized market of commercial surrogacy in India, and with clinics compromising on ethics, there is an urgent need for formulation of regulative law for the clinical practice and maintenance of principles of reproductive ethics in order to ensure that the interests of surrogate mothers are safeguarded.

The global impact of Dobbs v. Jackson Women’s Health Organization and the backlash towards reproductive justice that it represents warrant a global feminist response informed by broad theoretical and geopolitical lenses. We consider how a solidaristic, transnational feminist movement might learn from Latin American feminist movements that have been successful in uniting broad coalitions in the fight for reproductive justice as situated within far-reaching political goals. The success of such a global movement must be decolonial and must (...) contend with the fact that overlapping realities of global inequality, severe poverty, extractivism, and western-backed violence are fundamentally implicated in reproductive justice.

The possibility of human reproductive cloning has led some bioethicists to suggest that potentiality-based arguments for fetal moral status become untenable, as such arguments would be committed to making the implausible claim that any adult somatic cell is itself a potential person. In this article I defend potentiality-based arguments for fetal moral status against such a reductio. Starling from the widely-held claim that the maintenance of numerical identity throughout successive changes places constraints on what a given entity can plausibly (...) be said to have the potential to become, I argue that the cell reprogramming that takes place in reproductive cloning is such that it produces a new individual, and so adult somatic cells cannot be potential persons.

The successes of the human genome project and genomics research programs portend great potential to improve upon health and enhance life. As scientific advancements continue, bioethicists and policy makers deliberate over the social and ethical implications of genetic and genomic technologies and information (ggT/I). The application of ggT/I to human reproduction raises conceptual and moral questions about being human and the links between offspring, parents, and society. Given ggT/I’s ability to significantly affect the biological constitution of humans and future human (...) generations thinking through such issues is fundamental to ethical and policy analysis. By means of a systematic literature review and accompanying content analysis, this paper highlights the dominant ethical concerns raised within recent bioethics discourse over the use of ggT/I for human reproduction. Based on these findings it aso offers a framework through which, and demarcates where, religious perspectives can add value to genethics debates and policy deliberation. (shrink)

The aim of this study is an analysis of the possible adaptive consequences of delivery of low birth weight infants. We attempt to reveal the cost and benefit components of bearing small children, estimate the chance of the infants’ survival, and calculate the mothers’ reproductive success. According to life-history theory, under certain circumstances mothers can enhance their lifetime fitness by lowering the rate of investment in an infant and/or enhancing the rate of subsequent births. We assume that living (...) in a risky environment and giving birth to a small infant may involve a shift from qualitative to quantitative production of offspring. Given high infant mortality rates, parents will have a reproductive interest in producing a relatively large number of children with a smaller amount of prenatal investment. This hypothesis was tested among 650 Gypsy and 717 non-Gypsy Hungarian mothers. Our study has revealed that 23.8% of the Gypsy mothers had low birth weight (<2,500 g) children, whose mortality rate is very high. These mothers also had more spontaneous abortions and stillbirths than those with normal weight children. As a possible response to these reproductive failures, they shortened birth spacing, gaining 2–4 years across their reproductive lifespan for having additional children. Because of the relatively short interbirth intervals, by the end of their fertility period, Gypsy mothers with one or two low birth weight infants have significantly more children than their ethnic Hungarian counterparts. They appear to compensate for handicaps associated with low birth weights by having a larger number of closely spaced children following the birth of one or more infants with a reduced probability of survival. The possible alternative explanations are discussed, and the long-term reproductive benefits are estimated for both ethnic groups. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Male Reproductive Strategies in Sherwood Anderson's "The Untold Lie"Judith P. SaundersSingled out repeatedly as one of the finest stories in Sherwood Anderson's Winesburg, Ohio, "The Untold Lie" (1919) has attracted surprisingly little sustained critical comment.1 Like all the stories in the Winesburg cycle, this one delineates a revelatory moment of inner turmoil. There is little outward action; conflict and suspense are generated chiefly in the interior of the (...) protagonist's psyche, focusing on his ambivalence as husband and father. Readers become privy to "the buried life" of unacknowledged impulses and the "hidden truth" of repressed resentments,2 as Anderson's central characters struggle with the antithetical "choices available to the individual as biology works its will."3 A portrait of the male mind deliberating the relative advantages of alternative reproductive strategies, the story notably repays biosocial investigation. The theoretical framework, as well as the intellectual rationale, for undertaking biosocial investigation of literary texts has been explained ably by critics and aestheticians such as Joseph Carroll, Brett Cooke, Ellen Dissanayake, Robert Story, and others. Readers unfamiliar with the historical and theoretical foundations of Darwinian literary criticism will find useful commentary in works by these and other thinkers in this rapidly growing field.4Anderson concentrates on the interactions between two men at different stages in life, one middle-aged, perhaps fifty, and one youthful, "only twenty-two."5 The older man, Ray Pearson, has made his most important reproductive decisions well before the story begins: he has been married for many years and fathered half a dozen children (p. 203). He works as a farm hand, eking out a meagre living for his family by means of hard physical labor. A few details are sufficient to suggest [End Page 311] his poverty: his house is "tumble-down," his children "thin-legged," his coat torn and shiny with age (pp. 203, 206). Ray's wife, "sharp" in both features and voice, appears to be a perpetually anxious scold, concerned with fundamental problems of family subsistence. Ray's direct fitness (as measured by reproductive success) promises to be respectable, but the task of rearing his numerous offspring to adulthood has required and will continue to require his utmost effort and full-time commitment. He is just barely able to support his family (food is being purchased on a day-by-day basis), and there is little margin of safety in his situation.As foil to Ray, Anderson presents Hal Winters, a man not only younger but different in physique, in temperament, and in social class. Hal is big, tall, and broad shouldered; by way of contrast, Ray's shoulders are described as "rounded by too much and too hard labor," and he is "almost a foot shorter" than the robust Hal (p. 203ff). Inclined to prototypical masculine display, Hal is observed "roistering" about the town at night, dressing in "cheap flashy clothes." He challenges his own father in a fist fight, and as a result he is arrested and jailed. His brash and often reckless behavior is very unlike that of the "quiet, nervous," and "altogether serious" Ray. In the community Hal has the reputation of "a bad one." A fighter, a drinker, and a womanizer, he is "always up to some devilment." Unsurprisingly, Hal's family background is said not to be particularly respectable. The fathers of both Hal and Ray are small-business owners: the Winters operate a sawmill, the Pearsons a bakery. (The narrator never explains why Ray did not join or succeed his father in the bakery business, which presumably would have offered him a better income and a physically less onerous profession.) The stated difference in social standing appears to derive from the two families' differing records of conduct.Hal's aggressive propensities seem to be at least in part hereditary. He is "the worst" of three notoriously bad brothers, all sired by "a confirmed old reprobate" (pp. 202–3). The father, old Windpeter Winters, is remembered best for the gratuitous violence of his death. Drunk, he drove his team of horses along the railroad tracks straight into the path of an oncoming train, having slashed with his whip at a neighbor who... (shrink)

In this paper I will discuss three areas in which advances in human reproductive technology could occur, their uses and abuses, and their effects on society. First is the potential to drastically increase the success rate and availability of in vitro fertilization and embryo freezing. Second is the ability to perform biopsies on embryos prior to the onset of pregnancy. Finally, I will consider the adding or altering of genes in embryos, commonly referred to as genetic engineering.As new (...) reproductive technologies pass from experimental models into the potential for medical utilization, I believe that it will be important for lawmakers everywhere to avoid the impulse to outlaw procedures that a society believes to be unnatural at a first glance. Rather, I would hope that they can respond thoughtfully with legislation that serves two purposes — to protect the rights of couples to overcome infertility or to reduce the risk of genetic disease in their children-to-be, and more importantly, to protect children-to-be from the abuses that could result from some of the practices that I will discuss.

Studies of multiple paternity in mammals and other animal species generally report proportion of multiple paternity among litters, mean litter sizes, and mean number of sires per litter. It is shown how these variables can be used to produce an estimate of the probability of reproductive success for a male that has mated with a female. This estimate of male success is more informative about the mating system that alternative measures, like the proportion of litters with multiple (...) paternity or the mean number of sires per litter. The probability of success for a mated male can be measured both theoretically and empirically, and gives an estimate of the intensity of sperm competition and of a male's “confidence of paternity” upon mating. The probability of success for mated males for ten “exemplar” species of mammals is estimated and they are compared for insights into the functioning of their mating systems. (shrink)

Violations of women’s sexual and reproductive health and rights are frequent all over the world. Women’s sexual and reproductive health is related to multiple human rights. The term ‘rights-based’ has become increasingly linked to the concept of a more comprehensive approach to sexual and reproductive rights of women around the globe. The rights-based perspective is derived from the treaties, pacts and other international commitments that recognize and reinforce human rights, including the sexual and reproductive rights of (...) women. We conducted an extensive review of the guidelines, frameworks, research reports and published articles that have been cited as informing the rights-based approach. The findings of the review highlights what is meant by sexual and reproductive health and rights by the stakeholders, why this matter is important, and what can be done. It demands more partnerships with human rights, women’s and other civil society organizations, increased number of successful national policies, initiatives and/or legislative changes, increased budget and other resources at national and/or local community level, mass communication and engagement of men to promote and advance women’s sexual and reproductive health and rights. Achievement of gender equality is very crucial, because it is a human right that advances women’s empowerment; and is interlinked with sexual and reproductive health and rights. (shrink)

Since the decade of the 1970s, and particularly since the first successful test-tube baby in 1978, the development and use of assisted reproductive technologies have grown exponentially. Would-be parents—including those in so-called traditional male-female marriages, unmarried adults, postmenopausal women, and same-sex partnerships—who just over 20 years ago had no recourse for their fertility issues can now pursue their desires to have children with at least a partial, if not, total, genetic and/or biological relationship. Ovulation-stimulating medications, artificial insemination using the (...) sperm of a husband or unrelated donor, in vitro fertilization with embryo transfer, intracytoplasmic sperm injection, and gamete and zygote intrafallopian transfers are but a few of a host of treatment options ranging in complexity, invasiveness, and expense. And on the horizon are genetic techniques such as cloning—which was once considered “pure” science fiction but in 1997 became what some call an inevitability, with the development of mammalian cloning in the form of the now-famous Dolly the sheep.
