Modern Wisdom Podcast Episode #977: Dr. Robert King - Why Does The Female Orgasm Exist?
Release Date: August 7, 2025
In this compelling episode of Modern Wisdom, host Chris Williamson engages in an enlightening conversation with Dr. Robert King, an evolutionary biologist and author of Naturally Selective. The discussion delves deep into the enigmatic nature of the female orgasm, exploring its evolutionary purpose, underlying biology, and societal implications. Here's a comprehensive summary of their rich dialogue.
1. Dr. Robert King's Journey into Studying Female Orgasm
Dr. Robert King begins by recounting his unexpected transition from a schoolteacher with interests in psychology and mathematics to a pioneer in evolutionary biology studying female orgasm.
"[00:04] Dr. Robert King: ...about female orgasm did nothing, had no function. And to say I was surprised would be an understatement."
His curiosity was piqued by Elizabeth Lloyd's seminal work, prompting him to challenge prevailing scientific biases and seek original research in the field.
2. Critique of Historical Sex Research
Dr. King critically examines foundational studies on female orgasm, contrasting the methodologies and conclusions of Masters and Johnson with those of Dr. Fox and his wife.
"[02:34] Dr. Robert King: ...their research into female orgasm was to get half a dozen women to masturbate orgasm in a lab... and that female orgasm didn't really have any function."
He highlights the limitations of lab-based research, emphasizing the importance of studying sexuality in more natural settings to capture its full complexity.
3. The Adaptive Functions of Female Orgasm
Challenging the notion that the female orgasm is merely a biological byproduct, Dr. King presents evidence supporting its adaptive significance.
"[12:47] Dr. Robert King: ...oxytocin mediated peristalsis... creates pressure changes that could increase fertility."
He discusses the role of oxytocin in facilitating sperm transport and fostering maternal bonds, suggesting that orgasms enhance reproductive success.
4. Predictors of Female Orgasm
Dr. King's research identifies key factors that influence the likelihood of women achieving orgasm:
-
Attractive Partner Smell: Indicative of genetic compatibility.
"[25:45] Dr. Robert King: ...attractive partner smell... genetic compatibility."
-
Dominance and Considerateness: Women seek partners who are both sexually dominant and considerate, balancing strength with emotional intelligence.
-
Penetrative Vigor: The physical aspect of penetration plays a significant role in facilitating orgasm.
He underscores that these factors are not merely superficial traits but deeply rooted in evolutionary biology.
5. Cultural and Evolutionary Perspectives on Female Sexual Competition
The conversation shifts to the dynamics of intrasexual competition among women, exploring how cultural narratives and evolutionary pressures shape female sexual behavior.
"[33:22] Dr. Robert King: ...women are more choosy... they have to use subtle forms of status interplay."
Dr. King explains how cultural constructs like "venting" serve as covert strategies for women to navigate sexual competition without overt conflict, a necessity given their historical and biological vulnerabilities.
6. Impact of Hormonal Birth Control on Orgasm
Dr. King touches upon the under-researched area of how hormonal birth control may affect women's orgasmic experiences, suggesting that hormonal manipulation could influence both desire and physiological response.
"[69:04] Dr. Robert King: ...hormonal birth control affects who they find attractive. We haven't actually studied whether it has an effect on their orgasms."
He emphasizes the need for more comprehensive studies to understand these impacts fully.
7. The Orgasm Gap and Sexual Satisfaction
Addressing the persistent orgasm gap between men and women, Dr. King discusses its roots in both physiological differences and societal expectations.
"[71:03] Dr. Robert King: ...men are very likely to orgasm through penetrative sex, whereas women often require additional stimulation."
He notes that societal norms often place the onus on men to understand and fulfill women's sexual needs, contributing to disparities in sexual satisfaction.
8. Female Sexual Agency and Deceptive Strategies
The dialogue delves into the complex nature of female sexual agency, highlighting how women may employ deceptive strategies, such as faking orgasms, to navigate social and sexual landscapes.
"[88:53] Dr. Robert King: ...women hold up half the sky. But they also produce half the... a sexually reproducing species."
Dr. King argues that these behaviors are evolutionary strategies aimed at maximizing reproductive success while managing social dynamics.
9. Modern Sexual Culture and Its Effects
Chris and Dr. King explore how contemporary media and cultural narratives influence female sexual behavior and expectations.
"[83:33] Interviewer: ...shows like Love Island... normalizing conversations around female sex."
They discuss the tension between empowering narratives and traditional evolutionary pressures, emphasizing the complexity of modern sexual relationships.
10. Conclusion and Recommendations
As the episode wraps up, Dr. King recommends further reading and expresses hope for future research to unravel the remaining mysteries of female sexuality.
"[90:37] Dr. Robert King: ...I've got the book, it's called Naturally Selective..."
He advocates for a more nuanced understanding of female sexual behavior, free from societal biases and informed by rigorous scientific inquiry.
Key Takeaways:
- The female orgasm has evolutionary functions beyond mere pleasure, potentially enhancing fertility and fostering maternal bonds through oxytocin-mediated processes.
- Historical research on female orgasm has been biased, necessitating fresh perspectives and methodologies that encompass naturalistic settings.
- Predictors of female orgasm include partner's scent (a marker of genetic compatibility), dominance coupled with considerateness, and the physical vigor of penetration.
- Cultural narratives and intrasexual competition among women play significant roles in shaping sexual behaviors and strategies.
- There is a critical need for more research on how hormonal birth control impacts female orgasm and overall sexual satisfaction.
- The persisted orgasm gap is influenced by both biological differences and societal expectations, underscoring the importance of mutual understanding in sexual relationships.
- Modern sexual culture, influenced by media and evolving social norms, continues to shape and sometimes complicate the dynamics of female sexuality.
Notable Quotes:

- "If nature needs you to do a job which would otherwise be a choreograph, then it makes it pleasurable." — Dr. Robert King [10:15]
- "Female groupies... make sense because... they may have sons who feathers are also brighter." — Dr. Robert King [30:46]
- "Female sexual selection works... women are being picky." — Dr. Robert King [78:47]
- "Female sexual selection is inherently quite a comparative one... computationally just intractable at this point." — Dr. Robert King [81:09]
