I like to sleep most nights "tucked" as I like the feeling and look of my panties.

My question is...has anybody heard/read that this is a form of testosterone blocker?  As I have heard the balls hand low from the body to help produce sperm.  Or am I all wrong here?  Where the heck is testosterone produced? 

The testes do hang outside of the body to keep them cooler. (Extra point questions class, which side is lower? And why?  ) The reason is for sperm production. The little wigglers hate the heat.

Well, sperm isn't testosterone... but I wonder if tucking over a long period of time can lessen the effectiveness of the hormones creation.

I have never heard of this. BUT I also believe that it's reasonable to emit the hypothesis, from the established fact that tucking reduces sperm production, that testosterone production is affected as well. But I haven't seen any proof of this or the contrary yet.

Edit: Oh, and yes, testes produce the vast majority of testosterone.
