I am 36 years old. Never had normal sexual functions (meaning no libido, no erections, erection achieved with difficulty and only manually). During my teens never had erections, the first time I got an erection was when I was in my twenties. My genitals are very small, penis is childish size when flaccid and 5,5 inches when erect. Testicles measure 12 ml. Otherwise I am very masculine. Recently I have done some endocrionological tests (too late but no-one had previously referred me to an endocrinologist). Testosterone is normal, but very low Inhibin B at 77 ng/l, and high FSH at 14 mIU/ml. Semen analysis showed low normal sperm count with reduced motility. What could be wrong with me? I have even started reading about genetic disorders that could be causing my symptoms. Please help. In my country doctors are not sure.
