The effect of wearing tight clothes on the sperm production rate for some men.
please help

Although some studies have shown a decrease in sperm count from wearing tight-fitting underwear, others have not.
The testicles may seem like they just get in the way sometimes. But the main reason "the boys" are on the outside of the body is because the body's internal temperature of 98.6°F is too hot for sperm production. So by "hanging out," the scrotum keeps sperm a few degrees cooler.
Too much heat can lower sperm count (but not enough to act as a form of birth control). So tight clothing and underwear that keep testicles closer to body heat might, in theory, affect sperm count. But many experts think there isn't enough of a temperature change to make any significant difference.

This bacteria must be very strong as it has a large amount on antibiotic targeting it. this bacteria could be one of many different types and it is very hard to tell which one with out more information.
