Hello Anonymous and welcome to EmpowHER.
Yes, it is possible to have only one ovary removed during surgery if only one ovary has been impacted by a medical condition that would warrant removal.
It is highly likely that you would be a candidate for a type of surgery known as laparoscopy which is far less invasive than traditional surgical techniques. This procedure involves inserting a lighted viewing instrument called a laparoscope into the lower abdomen through a small incision.Complete hysterectomies are even done with this procedure and the recovery period is much quicker than with open, invasive surgery.
You can find detailed information about this procedure, including diagrams, on this page of the EmpowHER website: Laparocopy
When are you having your surgery and are you in pain?
We wish the best for you, please let us know how everything goes.
