Why this page is written the way it is
Testosterone for women is heavily marketed, and most of what is claimed for it is not supported. It is sold for energy, focus, motivation, muscle, sleep, and general vitality. Randomized trials do not show those benefits.
There is one indication that holds up: hypoactive sexual desire disorder in postmenopausal women. The 2019 Global Consensus Position Statement, endorsed by the major menopause and endocrine societies, reviewed the evidence and reached that conclusion, and it explicitly did not support prescribing for the other indications.
So this page tells you the same thing we would tell you in the room, which is that there is a real indication, the benefit for it is modest, the use is off-label, the long-term safety data are limited, and everything else being advertised is not established.
What we do before prescribing
Low sexual desire usually has more than one cause, and testosterone addresses only one of them.
If sex hurts, desire will not return until the pain does not. Genitourinary syndrome of menopause is the most common reason, and treating it with vaginal estrogen resolves the problem for a large share of women who thought they had a desire problem.
If you are depressed, or exhausted, or taking a medication that blunts desire — SSRIs are the common one — that is where to start. If the relationship is the issue, a hormone will not fix it, and saying so plainly is more respectful than prescribing around it.
We work through all of that first. Sometimes the answer at the end of it is testosterone. Often it is not.
If we do prescribe it
We use a small measured amount of an FDA-approved transdermal product at roughly one tenth of a male dose. We check a baseline level to make sure you are not already high, recheck it a few weeks in, and confirm you stay within the normal premenopausal female range.
We watch for androgenic effects. Acne and unwanted hair growth are dose-related and reversible. Voice deepening may not be, so any voice change means stopping immediately rather than waiting to see.
We set a six-month trial with a defined way to measure whether it helped. If it has not, we stop. Continuing an off-label hormone with modest average benefit and limited long-term safety data, when it is not working, is not something we will do.
