I have a question about mumps: I had mumps while I was thirteen-years-old. I remembered that because of embarrassment. I was afraid to tell my parents about the inflammation (swelling of the testicles) at the same time I had mumps. I did not have treatment for the swelling of my testicles due to mumps. Later, the swelling went away about the same time as my mumps. Although I still can produce semen, I am deeply disturbed whether that swelling could have hindered my fertility (i.e., no production of sperm due to the blockage of the sperm channels).
