Problem Set 8 Flashcards
Why are reproductive health studies biased towards women?
Reproductive health studies have historically focused on women due to the direct involvement of female physiology in reproduction, pregnancy, and childbirth. This focus has often overshadowed the role of male reproductive health and the dynamics of male-female interactions in reproduction. Additionally, societal norms and health care practices have often placed women at the center of reproductive health discussions.
What limitations have there been in terms of women’s reproduction studies in the past?
Limitations in women’s reproduction studies have included:
A lack of diversity in study populations, often focusing on specific demographics (e.g., white, middle-class women).
Insufficient attention to the social, cultural, and economic factors affecting women’s reproductive health.
Over-reliance on clinical settings, which may not reflect real-world reproductive behaviors and experiences.
Historical exclusion of women from clinical trials, leading to gaps in understanding how treatments affect women specifically.

What aspects of women’s reproductive ecology are different from that of other mammalian females?
Aspects of women’s reproductive ecology that differ from other mammalian females include:
Menstrual cycles: Unlike many mammals that have estrous cycles, women experience menstrual cycles, which may influence reproductive strategies and social dynamics.
Cryptic ovulation: Women do not exhibit overt signs of ovulation, which is common in many other species, potentially influencing mate selection and social interactions.
Longer reproductive lifespan: Women have a longer period of fertility compared to many other mammals, which may affect reproductive strategies and social structures.
What hypotheses have been proposed to explain women’s “cryptic” ovulation?
Mate selection hypothesis: Cryptic ovulation may promote female choice in mate selection, allowing women to assess potential partners over time without revealing their fertility status.
Paternity confusion hypothesis: By concealing ovulation, women may reduce the risk of infanticide by multiple males, as it becomes difficult for males to ascertain paternity.
Social bonding hypothesis: Concealed ovulation may enhance social bonds and cooperation among females and between sexes, fostering a supportive environment for child-rearing.
What are the benefits and costs of continuous ovulation?
Benefits: Continuous ovulation can increase reproductive opportunities, allowing for more frequent mating and potential conception. It may also enhance genetic diversity in offspring.
Costs: Continuous ovulation can lead to increased energy expenditure, higher risks of reproductive health issues, and potential trade-offs with other physiological processes, such as immune function.
What adaptation may have arisen to counter those costs?
One adaptation that may have arisen to counter the costs of continuous ovulation is the development of hormonal regulation mechanisms that optimize reproductive timing and energy allocation. This includes the ability to suppress ovulation in response to environmental stressors or social factors, allowing for more strategic reproductive planning.
Can women’s orgasms be seen as adaptive? If so, how?
Yes, women’s orgasms can be seen as adaptive in several ways:
Sperm retention hypothesis: Orgasms may facilitate sperm retention and transport within the female reproductive tract, increasing the likelihood of conception.
Pair bonding hypothesis: Orgasms may enhance emotional bonding between partners, promoting long-term relationships that can provide support for raising offspring.
Reproductive health hypothesis: Regular orgasms may contribute to reproductive health by promoting uterine contractions and improving blood flow to the reproductive organs.
