I had a partial and, in agreement with my doctor, left my ovaries in. There are truly many factors to weigh in this decision. For me, it was my age, and the fact that I wanted the option to explore surrogacy down the road (which I did and it resulted in twin boys). But other considerations came into play as well such as the length of time I had been on birth control, family history, etc. You really need to weigh all options and consider what the ex post facto scenarios are as well in terms of HRT etc. Another source of info for this particular topic--and one that I found helpful at the time--is hystersisters.com.
