I am having a hysterectomy for uterus prolapse should I have my ovaries removed? I am only 24.?

I also have endometriosis, a cyctocele & rectocele. The doctor is planning on doing a l hysterectomy, cyctocele repair, retocele repair and hemroidectomy. She will be using a camera to look and see if my endometriosis is bad enough to remove my ovaries. If she doesn't think it is, she wants to leave them. I have never had pain from endometrosis just very heavy bleeding. The doctor has told me if they take them out I will have advanced Osteoporosis by the time im 40. Leaving them in leaves my at a higher risk for uterine cancer, or they just might die. I just don't know what to do everyone has an opinion. Also, I have heard hormone therapy causes cancer. My life is also a great concern as I have heard of dryness. I am married with one girl and one boy and child bearing is no longer an issue im done.
