Very interesting new data that estrogen levels factor into male sexual function. This could revolutionize the treatment of ED and other issues that, until now, have been treated with testosterone alone.
TV ads tout testosterone treatments for "low T," but surprising new research shows a different hormone may play a role in less sex drive and more fat as men age. Estrogen — the female hormone — is needed by men, too, and the study gives the first clear evidence that too little of it can cause certain "male menopause" symptoms.
From a sexological point of view, it's also very encouraging to see new and challenging data on androgens. The more we learn about the biology of sex, the better we will also understand their role in gender differentials.
