Testicle needs a stable temperature in producing good quality of sperm. Sleeping without underwear is good for men who are diagnosed for suffering from infertility. It is said on the research of reproduction that testicle is able to produce a good quality of sperm under 36,67 ‘C or 98 ‘F.

Sleeping without underwear also decreases the temperature in the prostate gland so that sperms production becomes normal and the blood flow to penis expedites. As a result, we will be prevented from erectile dysfunction.
