I also had a hard time finding the "right" HRT but I don't have ovaries or a uterus. My surgery was also for an ovarian cyst; my uterus was healthy. I miss it more than my ovaries because I miss the intense uterine orgasms and I've lost most sensation. I don't have any desire either even though my HRT seems fairly settled. I had great libido before.
Estrogen without an adequate dose of a progestin or progesterone increases risk of endometrial hyperplasia and cancer. However, hyperplasia oftentimes never develops into cancer and if it does, it generally takes many years. Here's what appears to be a comprehensive link on Endometrial Cancer (from the American Academy of Family Physicians) -
http://www.aafp.org/afp/1999/0601/p3069.html. There's a section on Hormone Replacement Therapy about 1/3 of the way down the page.
I personally know several women who went into early menopause and still have all their parts. They've been on hormones for decades and haven't developed cancer. They have periodic ultrasounds to check the thickness of their uterine lining.
There are a number of ways to protect your lining that come to mind:
- A combined HRT. Some that come to mind are (oral) Prempro, Enjuvia, Activella, and (transdermal) CombiPatch.
- A progestin or progesterone taken separately from your estrogen. It can be taken continuously or cycled (to force a bleed and thin the lining). There are oral and vaginal options.
- An IUD (Mirena) - provides a slow continuous release of progestin.
- A low dose birth control pill or vaginal ring (Nuvaring)
Sometimes it takes trying various HRT's to find the one that's best for you. I don't know how many you've tried.
Has your doctor done any diagnostics to show that your uterus has a proliferative lining? A transvaginal ultrasound will show the thickness of the lining. If it's thick, maybe forcing a bleed with a progestin would be all that's needed. An endometrial biopsy or D&C would show any abnormal cells if the lining is thick.
The uterus is a sort of "place holder" for the bladder and bowels. Do a web search for "pubmed organ vaginal prolapse post hysterectomy" and read through the various studies. I've been dealing with bowel problems since surgery.
If you feel like your doctor isn't willing to support your wishes, seek out another doctor(s). I hope you've found my information helpful.
