Dear sir/madam, I am murad hasan, male and 32 years of age. I am 5?5?? and weighs 58 kg. I am unmarried. When I was 14 years of age I had an orchitis in left testicles but the right one was fine. After treatment with some medications without any kind of surgery, I became fine within 1 week. But, after passing some 4 or 5 years I noticed that, the testicle is getting smaller than the normal size and gradually it becomes very small perhaps, it has been withered. But, still I am ejaculated when nocturnal emotions occur and my penis erects when I feel excited. My question is: is there still any risk present on that testicle or will the right one which is fine be affected later? How can I keep it healthy for my next life? As I am unmarried and going to marry soon, can I be able to lead healthy sexual life with my single testicle or be able to make my wife pregnant? To do so, is there any advice from you? Thanks, murad hasan.
