TESTICLES maintain a constant temperature for the semen they store, maintaining a constant temp for the sperm. The testes are like an automatic thermostat. When the temp is too high (lowering sperm count), the testicles drop down to cool off. When the temp is too low (lowering sperm count) the testicles go up into the body to get warm. THEREFORE, when you wear briefs, the testicles stay up, in a warmer position. Briefs don't allow the "automatic thermostat" to work efficiently. THIS is why if you are trying to have children, and have a slight low sperm count, the doctor will tell you to wear boxers to allow the testes to do there job by raising and lowering, depending on temp, to give you the highest sperm count possible. So in answer to your question: YES.
If you're thinking this may be a form of contraception - you're very wrong.
sperm dies
1) working in hot environment continiously. 2) wearing tigt undergarments.
Not the volume, but it may reduce the number of viable sperm. Tight fitting underwear keep the testicles too warm.
It will not harm you, doctors say you should wear loose underwear to increase your sperm.
If the sperm is fresh yes. If the sperm is old no.
No. Viagra does not affect sperm count.
Yes, a lack of sleep can have a negative effect on a male's sperm count. It has been reported that a lack of sleep can reduce a man's sperm count by a third.
You can get a vasectomy and have 0 sperm cells in your semen. To reduce the count you can add stress to your body, wear tight underwear or have one of your testicles cut out.
Yes, smoking can have a negative effect on sperm count. It has been linked to lower sperm count, decreased sperm motility, and abnormal sperm shape. Smoking can also increase DNA damage in sperm, which can affect fertility.
The tight boxers aren't to blame. Sperm are killed in the presence of high temperatures; that's why the testicles dangle down - to keep sperm cool. Tight clothing and hot baths can both reduce sperm motility. This is not to say that a jacuzzi is an reliable method of birth control; it isn't.
No. Sperm cannot survive outside the body for long
No. This is a very common myth related to sperm count. Documented causes of reduced sperm count are sitting in a hot tub, wearing tight undies, caffeine and some drugs can reduce sperm count.
