Is her vagina heathy? If not intercourse will be painful so she may want to avoid it. I was prescribed hormones after mesopause and all was well until I came to an age when they wouldn't prescribe them anymore. Within a few years my vaginal walls thinned and dried causing painful intercourse which I tolerated knowing how important it was for my husband and my marriage. Many women use a topical hormone cream inserted into the vagina but I had Allergic Contact Dermatitis and was allergic to inactive ingredients in these creams. My vaginal health has been completely restored using Estring, a silicone ring with time released estrogen, which is personally inserted into the vagina and replaced every 3 months and I am not allergic to. Unbelievable. I no longer dread intercourse but look forward to it. No more burning or pain.
Others mentioned testosterone added to their oral estrogen supplement. I was on Estratest for years, loved it. It is true that the testosterone in this pill
makes you more sexually aggressive. One side effect is growing a few chin hairs which are easily tweezed out.
My husband of 56 years has been supportive working through this with me. Ironically now his hormone levels have declined so he began doing research on how to increase his sexual desire. He is on testosterone injections and another injection to stiffen his penis these are successful treatments for him. The words to an old country song, "I'm not as good as I once was, but I'm as good once as I ever was", sums it up. We're both facing 80 in few years and not settling for sitting in a wheel chair.
I hope she keeps an open mind and works with you on this issue.
