Does treating endometriosis increase fertility?

There is some evidence to suggest that treatment of early stage endometriosis can improve fertility and I think more severe stages of endometriosis are less likely that surgery is going to be of benefit because remember that surgery is going to cause some scarring inside the pelvis. So the anatomy will be distorted not anymore because of the endometriosis if that has been excised but probably because of the presence of adhesions that occur in the pelvis as a result of the surgery.

Not necessarily but in certain cases yes. Specifically if the disease is superficial and mild, it has been shown that doing laparoscopic treatment increases the chance of spontaneous pregnancy but if the disease is severe, deep rooted and there is no research or no trials which show that doing surgery improves the chances of pregnancy in those cases. Usually
IVF is recommended, unless there is a very big ovarian endometriosis and the problem is to collect eggs from that ovary then, the drainage of that endometriotic cyst or deposit might be helpful but not complete removal of the endometriotic cyst exists in severe cases.
IVF is the answer in severe endometriosis but in superficial, mild endometriosis, laparoscopic surgical treatment can increase the chances of fertility.

Yes, it can and with the two ways of treating endometriosis: you can treat it by surgically removing it or by giving hormones to treat it. If I take the second treatment first, hormone treatment won’t improve your fertility, so if a patient is presenting to a clinician with where fertility is the primary issue, they’re usually offered surgery and surgery for minimal to mild endometriosis, we know improves the chance of getting pregnant without any intervention spontaneously if you like. If patients have more severe endometriosis, the data for surgery is less clear and often patients may choose to or undergo fertility treatments such as IVF when they have endometriosis and often this can be very successful.
