But perhaps just prescribing estrogen to these women could have achieved the same results without the potential side-(masculinizing) effects from testosterone.
This one interesting study on rhesus macaques, primates like us, showed that giving testosterone or estrone to females increased 2 out of 3 proceptive (courting) or sexual behaviors while estradiol given in a much lower dose increased all 3!!! DHT did nothing, nada! Also, not surprisingly, DHT and T did not affect male contact or mounting on females but both estrone and estradiol DID. So, estradiol not only increased female flirting and sexual play but made them more attractive sexually to males in contrast to T and especially DHT.
Also, very funny, is that both T and DHT increased yawning in females...hahahaha! while neither estrone nor estradiol did that.
I would say that estradiol is the clear winner, wouldn't you?
