What's the deal with ovarian cysts?

1) What are ovarian cysts? What do they feel like, and where would one feel the symptoms?

2) I just found out that I have a small cyst on my left ovary. I was wondering what causes these? Any risks with them? The doctor told me that they usually pass during a monthly period but I've been having this pain for several months already. Any advice? I haven't seen my GYN about this yet.

3) Both me and my husband are at Columbia University. I was recently diagnosed with ovarian functional cysts that are about one inch long each, in both ovaries. We are starting to think about having a baby. Do you think that having those cysts in my ovaries would decrease my chances of becoming pregnant? Thank you very much for your response.


What are the health effects of only having one ovary?

I'm a 19-year-old female. I had my right ovary removed (oophorectomy) three years ago due to a very large ovarian cyst. I was assured by my gynecologist that I'm still capable of bearing children but wasn't informed thoroughly of all of the pros and cons in regards to this type of operation (e.g., can the estrogen loss have any negative physical affects?). If you could shed some light on this matter, it would be greatly appreciated. Thanks.
