My wife has two chocolate cysts in her right ovary. She was suggested two options by our gynaec - 1. Direct removal by surgery 2. Reduce size of cysts by taking injection (Lupride Depot 3.75) for three months and then remove by surgery. We have taken our first injection last week. Now, the question is how many days after the third injection is taken can the surgery be done? We need to plan the dates properly due to family reasons. Also, is it necessary to take three injections or two injections will be alright?
