I have had ovarian cysts since I was about 16 years old. I get them every month. When my first husband and I were going through fertility treatments (we tried for 7 years) they put me on birth control pills basically every other month. They would find several cysts on my ovarys and the next month I would come in and they would be gone. They think that the cysts were a main reason as to why my first husband and I couldn't conceive. I am not sure if it is all in God's time or what, but I've been married to my new husband since July 21st of this year and I am now 7 weeks pregnant. I was spotting badly two weeks ago and they've since found 2 cysts, one is directly across from the sac. I have heard several people say that once pregnant it will help the cysts. But I can tell you from experience. Cysts can be very painful. I have learned the months that I have them and the ones that I don't.
As for if the doctors would consider a hysterectomy, if a condition gets to be harmful for your health they could reccomend that you have one. They may take your one or both of your ovaries. It would likely depend on if your body has cysts on both ovaries or just one of them.
If you are still needing an answer, let me know. I can ask a friend that is a nurse and both of her daughters have polycystic ovarian syndrome.
