Can changes in female genitalia i.e. clitoral shrinkage be reversed by hormone treatment ?
I am 49 years old snd currently not taking hrt, I have not had a period for 2 years and still have my womb.

I don't know about the clitoris changing size from HRT, but personally avoided HRT (for menopause) because of the ever changing data about the risks.

HRT should not be taken for this purpose. There are risks, including cancer, that are increased by taking HRT.
