Hi, I have what appears to be a 7cm endometrioma on my left ovary. I had surgery to remove an ovarian cyst on the same ovary a year ago and it regrew to the same size within 4 months. An interesting side note is that they tested my last cyst and there were no endometrial cells found, even though the cyst was filled with old blood. They are still calling my new cyst an endometrioma, even though they are not sure it actually is one. My GYN is now suggesting surgery to remove the entire ovary because it regrew so quickly. I would like to avoid surgery if at all possible because I had complications during my last one. Do you offer the ovarian sclerotherapy procedure? If not, do you know who would?
