I read the following in Larrian Reports today (it is free to anyone who wants it, but it is a commercial site so I won't post the link). Even though the study on testosterone didn't show benefit for sexual desire, I don't actually believe it (though I do not use it). There will be another study, if there wasn't one prior, that will say it works. I already know that DHEA works for me, regardless of what any study says.

Testosterone Levels Fail to Predict Female Sex Drive
"Efforts to pitch Testosterone Replacement Therapy as the Sexual Fountain of Youth got a sharp stick in the groin with the publication of these two studies. The first one measured testosterone and DHEA-S levels in women 45-75 and compared them with a sexual function profile. There was no correlation between low sex drive and low levels of either hormone. In the second study, testosterone replacement therapy with a patch had no effect on raising growth hormone levels or improving IGF-1 production in postmenopausal women. So if your doctor, courtesy of the pharmaceutical rep, wants to hand you a prescription for testosterone to rev up your sex drive - pass. Testosterone will only raise your bad cholesterol, grow hair on your face, raise your insulin levels and pack on the pounds, and that's not sexy!" JAMA. 2005;294:91-96.
