The production of healthy sperm requires a cool environment, about 3 or 4 degrees C lower than core temperature. Thus keeping the testicles warm will result in malformed batched or sperm that will be next to usless fertily. But this will only affect the batched produced when the testicles are warm and so no long term effects like sterility occur.
No this will not make him sterile.
Not sterile but it can surely reduce the viability of your sperm. The testicular sac is situated outside the body for just this purpose. The heat weakens the sperm mobility.
No but they will make his bread rise
No.
No.
No.
No. It's usually surprisingly clean, and depending on the process, mave hjave been exposed to heat high enough to sterilize, but it should not be considered "sterile" in that no steps have been taken to make it so or protect it in the sterile state.
no .
"sterile" means that all microbes have been killed by radiation or heat.
It can 'shrink' your testes........somewhat
Better question. Are you a junkie?
