Do mumps and swollen testes affect fertility?

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).


What are the risks of gel and shellac nail manicures?

I love getting my nails done with a gel or shellac manicure. The polish doesn't chip at all and stays shiny for weeks. I'm just worried about the UV light used to seal the manicure - it is almost like a mini tanning bed for your hands. What are the risks? And are there any bad chemicals in the polish?


Why do dairy products suddenly taste bad?

I have a weird problem that happened to me once when I was maybe 8 years old (I'm 20 now). I woke up one morning and all dairy products tasted horrible. They tasted as though they had gone bad. I'm not sure how long it lasted back then because I just stopped eating all dairy products for a couple of years — I was afraid they would taste bad, but it definitely lasted several months. When I started to have them again they tasted fine. It seems to have started again. What could possibly be the cause of this?
