I don't have prolactinoma but I got tested for it. I had low libido as a man with ED problems, I went to a Urologist and he prescribed a whole bunch of tests which includes checking your Prolactin levels as well as SHBG, FSH, LH,Testosterone, E2 etc.

I suppose an Endocrinologist would run the same tests.. in my case I had Secondary Hypogonadism and was put on HCG (Human Chorionic Gonadotropin) which resolved my Testostrone issues and libido and improved my sperm count as a nice bonus.

But I digress, the point is that if you suspect any issues, go see a doctor!
