I had an ovary removed last May and while I have had other problems, I did not experience any hormonal symptoms from having one ovary removed. I did have a few nights of night sweats right after the surgery, but that was short lived and may have just been the pain medicine.
I can't speak about pregnancy, because I did not try to get pregnant afterward, but my doctor did say, as yours did, that missing one ovary will not affect fertility.
I am sorry no one has responded. I am sorry your doctor has not been very helpful and certainly not upfront. Hopefully, your other ovary will compensate for the one that was removed. But that does not always happen. If you do not conceive soon, you may want to see a fertility specialist or reproductive endocrinologist. Best of luck to you and I hope you are recovered and all is working fine soon!
