There is a you tube video that discusses the effects that a hysteretomy can have on all sorts of bodily functions, not just hormonally but structurally as well. The video is quite detailed, and could be confronting if you were facing having one. I can get you the link if you would like to see it.

I would be asking for more information, and more discussion on the different options for surgery. Maybe taking an advocate with you when you see the surgeon would help you to ask your questions, so you are more comfortable with whatever decision you make.
