Whether to treat a uterine septum is controversial. Those who believe it’s significant say that the embryo will be unable to implant on the septum because it has a poorer blood supply. Those who don’t believe this say, quite rightly, that there’s no evidence to prove that removing a septum increases fertility.
There’s also some evidence to suggest that miscarriage from cervical incompetence is more frequent after a septum is removed, presumably because other parts of the uterus are abnormal too, not just the septum. The problem is that proof of what is best would be very difficult to obtain. What we would need to do is to find perhaps 200 women, all trying to conceive and all with a septum, and then operate on half them and see how long it takes for each group to conceive. Operations for the removal of a septum are now quite simple for a specialised hysteroscopic surgeon.
Nevertheless, remember that complications can occur with even the simplest of procedures such as bleeding.There are many women who seem to have conceived immediately after a laparoscopy or other form of tubal investigation. Statistically (sadly), this appears to be just luck.
