HanSelo:estradiol being the primary hormone relating to female libido.
Some research suggests that supraphysiological testosterone levels in women may elevate sexual desire, but this is abnormal.
The studies that were mixed were using 1% cream at a dose of 5-10 mg per day. Absorption rate of creams are 10-20% at best. They're crap. The studies with MEN are mixed using creams and there is no debate that test drives male libido. Inject a female with 20mg of test propionate and ask her in 24hrs what she's feeling. It's not subtle. She'll be crawling up the walls within 48hrs.
Small doses of ANY strong androgen will turn a woman's world upside down with lust, particularly DHT and DHT derivatives, more so than testosterone itself (has higher affinity for the androgen receptor). This is why drugs that reduce SHBG all have a side effect of increasing libido because SHBG binds to androgens.
Vice versa, estradiol causes SHBG to skyrocket. This is why estradiol birth control notoriously craters libido.
I dated a number of bikini competitors that took small doses of androgens like Proviron, Stanozolol, Anavar or low dose test. And it was insane what even 5mg of a DHT derivative will do to the female libido. My one ex after two weeks on stanozolol had to wear a pad to work because she was soaking through her pants every day. Perpetually turned on. My other ex had to stop riding her Peloton bike on Proviron because she would orgasm.
The East German Olympic team was forcing its female athletes to take turinabol and the declassified team physician reports show 3 of the girls left the program because they couldn't psychologically handle the libido increase.
There are a ton of drugs that dramatically increase the female libido and the common thread is they all target the androgen or MC4 melanocortin receptors. They'll simply never be FDA approved for long-term use due to the effects on cholesterol, disruption of their cycle, HTPA suppression etc. In the end I still think it's sexist because men are going to any clinic and getting up to 600mg of test injections a week which is WAY harsher on your lipid profile and organs than the female drugs we know about.
