Saw an interesting segment on the Today show this morning about the connection between low libido and testosterone in women. Dr. Judith Reichman was the guest and she basically said there is no direct connection. I did a search for an article and did find one.
"The report in Wednesday's Journal of the American Medical Association questions the assumption among sex researchers that low sexual desire in women has roots in low levels of testosterone or certain related hormones. If a woman with low libido walks into her doctor's office and asks for a blood test to see if she can use that new testosterone patch, well, there's no basis for that," said lead author Dr. Susan Davis of Monash Medical School in Victoria, Australia. "They're totally uninformative."
Apparently the key is not a woman's level of testosterone but how much those levels may have changed over time. Makes sense to me since my testosterone level is fine and my libido is not. I don't know what my levels were before menopause. I think that's a good case for testing your hormones before menopause so you know what the normal levels are for you.
