What are the effects of a total hysterectomy with the ovaries left behind?

Can you answer Ajane’s question about Menopause?:

I am 23 years old and mother of 2. I am going through issues with severe dysplasia that is getting worse. It is a genetic thing. With the birth of my last child, my uterus ruptured so it is now really weak on one side and pregnancy is pretty much out of the question. I am seriously considering a total hysterectomy with the ovaries left behind for hormone production. My family is really against the procedure because they are scared it will mess with my hormones and make me crazy. I really need all the information I can get before I willingly decide to go through with the surgery.
