What are the scientific benefits/drawbacks of wearing underwear for boys?

Wearing underwear isn't a strict necessity for boys, but it does serve some purpose. If you don't wear underwear, the private parts aren't fully covered. Of course, many boys don't wear underwear at all. If it bothers you in the heat, you can go without it for a few days. Besides, wearing loose pants in the heat will also keep you comfortable. You can also wear cotton trousers or half pants for comfort. Boys' underwear should be clean, cotton, and loose-fitting. It's good to use light-colored underwear so that dirt is easily noticeable. Underwear must definitely be changed and worn fresh every day. This is especially important for those who sweat a lot or spend a lot of time outside — they need to go out wearing clean underwear daily. Using unclean underwear can cause odor, sores, and infections in the groin, penis, and scrotum area. Why boys should wear underwear Tight underwear should not be used, especially for boys going through puberty. During this time, the testes release a hormone called testosterone, which enlarges and shapes the genitals and drives the development of manhood. Using tight underwear can hinder this development. A recent study has stated that French men's sperm production capacity has dropped at an alarming rate. Even their sperm's ability to fertilize an egg has decreased dramatically. The main causes identified are tight underwear, lifestyle habits, diet, and so on. Experts made this claim in a study published in the journal Human Reproduction in 2012. This study is the largest survey ever conducted on male sperm. The research found that between 1989 and 2005 — a span of 17 years — sperm production in French men dropped by nearly one-third. At the same time, the fertilizing capacity of the sperm produced also decreased. The study also found that for 35-year-old men, the sperm count per milliliter of semen dropped from 73.6 million to 49.9 million. Researchers consider this rate of decline in sperm production alarming. According to the World Health Organization, for a man to be capable of fathering a child, his semen must contain, on average, more than 15 million sperm per milliliter. However, according to reproductive experts, a healthy man's normal sperm count ranges between 20 million and 150 million per milliliter of semen. Also, if you wear polyester — that is, synthetic — underwear instead of cotton, it may cause impotence. Even underwear made of a cotton-polyester blend can cause some degree of impotence. Does wearing underwear make the penis smaller? Answer: No. However, wearing very tight clothing can cause slight constriction, but it does not make it smaller.
