How Women Affect Men's Testosterone Levels

Video summary

The discussion centers on a potential hormonal component to what some call the "sex recession," suggesting it may be partly driven by women using hormonal birth control and men experiencing low testosterone levels. The conversation introduces Dr. Sarah Hill, author of *This Is Your Brain on Birth Control*, whose research indicates that male testosterone levels are biologically mediated by the fertility status of women in their local environment. According to this theory, when a man is surrounded by other males or older females like grandmothers and children rather than fertile partners, his testosterone naturally drops. Conversely, men can detect female fertility through scent alone; studies cited show that men find silhouettes most attractive during the seven-day window of peak ovulation, with high heels potentially mimicking this natural gait to enhance attractiveness. A significant argument presented is a recursive feedback loop where hormonal birth control causes women to select for male providers rather than protectors, prioritizing academic achievement and resources over traditional protective traits. This shift allegedly leads men into a "hormonal fugue state" or social confusion regarding their partners' true fertility status once they are in relationships with contraceptive users. The transcript notes that while society might prefer lower testosterone levels associated with less aggression and crime, there is also the concern of declining male vitality leading to issues like obesity, diabetes, and reduced military recruitment interest. This creates a difficult societal trade-off between fostering peaceful, "soy" men who are agreeable but potentially sterile versus maintaining higher testosterone levels that could correlate with increased violence or criminal behavior. The decline in male testosterone is highlighted as occurring at approximately 1% per year since the early 1950s, attributed not just to lifestyle factors like processed foods and lack of Vitamin D exposure, but also by an "X Factor" linked heavily to hormonal birth control usage among women. The conversation extends this issue globally, citing China's ban on K-pop as a strategic move against what they termed "[ __ ] men." In that context, the Chinese government reportedly sought to prevent their male population from adopting soft, feminine role models like BTS members in favor of "high T-jacked" figures associated with traditional masculinity. This cultural shift is linked historically to pre-communist Confucian values and a reaction against perceived feminization, contrasting sharply with communist-era ideals that favored intellectual or indoor-oriented men over the rugged physicality previously celebrated. The dialogue concludes by acknowledging the complexity of these hormonal dynamics without offering a definitive solution, noting that while low testosterone presents challenges for fertility and functional relationships between genders, high testosterone carries its own societal risks regarding violence. The military recruitment crisis is further complicated not just by health issues like diabetes but also by men's lack of interest in waging war, which may stem from diminished patriotism or faith in the nation rather than solely hormonal causes. Ultimately, the speakers suggest that as long as there are no active hot wars and technology advances rapidly, society might temporarily get away with these demographic shifts, though they warn that a scenario requiring mass mobilization could expose severe vulnerabilities if the pool of willing soldiers continues to shrink due to cultural and biological factors.

it is possible that the sex recession soall is partly hormonal it's partly caused by I mean it might partly be caused by women being on hormonal birth control which is changing their sexuality might also be caused by men being low te so the low testosterone for men do you want to hear my real horseshoe theory for this okay right so I learned this whil talking to Dr Sarah Hill who wrote this is your brain on birth control right and um she taught me that male testosterone levels are mediated by the fertility of the women in their local ecology so if you were a uh male in their 20s but you happen to be around a bunch of other men or a bunch of other grandmothers perhaps are a bunch of children your testosterone levels drop interesting and what you have are women who are very highly artificially suppressing their fertility so men are able to smell the T-shirt of a woman and be able to pick the one the one that they most attractive to is the attracted to is the one who is currently at that stage of her cycle she's currently fertile etc etc they can see they've done studies where men watch women's Silhouettes walking and the women who are currently during the 7day you can get me pregnant period they're the ones that the're most attracted to the [ __ ] silhouette of the way they walk display high heels replicate that that's the idea mhm the high heels make you walk distin make you look so you have this recursive uh feedback loop of hormonal birth control causes women to select for men who are more providers rather than protectors they want provisioners right they want the uh academic and the resources more agreeable they then either come off or don't come off birth control but find that they come out this [ __ ] hormonal Fugue State oh my God who am I in a relationship with but you also have this effect on men too only socially in I noticed that lots of women seem to be attracted to Timothy shalam who's painting his nails and kind of blah blah blah blah blah yeah but the genuine physiological hormonal response to men just being around lots of women who are on hormonal birth control now processed foods not enough time outside not enough time with vitamin D not enough time with friends but there's a big X Factor apparently amongst testosterone researchers who don't know why men's tea levels have dropped the amount that they have right it's about 1% a year every year since I think 1950 wow so it's like and then that goes to 100 and then it's that again and it goes to 100 so it's not how we're in minus [ __ ] uh testosterone soon but uh yeah so hormonal birth control has a lot to answer for I think it's a really tricky trade-off isn't it because like there are clear downsides to having a bunch of low team men you you know in terms of in terms of fertility in terms of men and women just fcing each other and like having functional relationships but also like high testosterone is also associated with crime and violence yeah so which you know do we choose to have a society of kind of sexless incredibly like online Placid soy people yeah who also are quite chill don't CA like enormous problems I don't know that's like that's like a genuinely hard thing to choose yeah you could almost look at it kind of like a disposition sterilization yeah in a way yeah yeah [ __ ] yeah but then we had problems with like like this is a real problem with the military I'm sure you know like massive recruitment problems I thought that was because everyone's fat and got diabetes Well that too right but also not being interested in it men just don't want to wage war yeah we can do it from Modern Warfare or um I'm on Reddit it's probably also partly to do with lack of like faith in the nation like being less patriotic in general like the pool of potentially great soldiers just get smaller every year and it's sort of fine I guess we get away with it because if we're not actually in a hot war and if we have loads of Technology but you can imagine a scenario where that becomes an enormous problem like a mass mobilization I don't know how we actually Fair the uh Chinese government banned K-pop you see this cuz they didn't want what was it they called them it was like [ __ ] men we don't want any more [ __ ] men so it was all of the Chinese male role models were like super high te jacked dudes and they didn't want this BTS Like soy like culture infecting them that's how they that's what I saw it something I learned about that from um I had a um R MIT who's a professor of Chinese history and politics Oxford on my podcast I didn't know this um in China there's a very strong association between communism and masculinity and actually it's the old pre-communist like Confucian soy boys basically you know the sort of the sort of like intellectual indoorsy that's associated with pre-communist China M and so some of the reaction against feminization through K-pop or whatever is associated with um anti-communist buing in
