I had the total removal last year when they discovered a mass in my uterus, at the age of 46. I didn't want to take chances considering my family history, and after the misery of dealing with PCOS for so many years, it was an easy decision. Seriously. It went like this...
Dr - Well, there's an unidentified mass in your uterus. We don't know...
Me - Take it all out!
Then I did a happydance.
I did have some sudden onset menopause issues right after the surgery, but they were really mild. I look back on it now and realize that my hormones were already so totally out of whack due to the PCOS that losing my ovaries didn't really phase me all that much. I took a hormone supplement for a couple of months, but a couple of weeks after stopping it, I haven't had any problems. Certainly not more problems than I had dealing with the PCOS.
Since the surgery I haven't had the constant abdominal pains, the mood swings, the reoccurring bladder infections, the periods that lasted a month or longer, the agonizing pain that felt like being violated with a baseball bat studded with broken glass every time a cyst ruptured... you guys know the list. I guess whether or not removal of your ovaries would help you would depend on how severe your PCOS is.
One thing I've found that I don't miss, which really surprised me, is that I really don't miss that constant need for gratification. I hate to bring up something so personal on a BBS, and I hope I don't offend people, but seriously, people don't discuss that and there's a lot of women out there who feel freakish or abnormal because of it. It reminded me of this cat I used to have who was constantly in heat... annoying, embarrassing, infuriating cat. We had her fixed and the vet found a tumor on one of her ovaries which was causing the constant flow of hormones telling her that she was in heat. I was afraid that the loss of that aspect of my sexuality would change me so much and that I would hate it. In fact, it's a relief. I find myself able to make more friends among men without viewing them all as potential partners, able to focus more on my family, my home, my work, my hobbies, able to normalize my own perceptions of self without that constant grating need driving some of my emotions and psychology. Looking back at that part of it, that aspect is rather like velvet handcuffs... some people feel like they have to have it and they build much of their sense of self around it, wearing their hypersexuality like a badge of honor, but you don't realize how much it limits your life until it's removed.
