How to distinguish good sperm from bad sperm

The most basic factor in judging whether a man is healthy and can normally conceive the next generation is the health of his sperm. If the quality of a man's sperm is poor, it may cause male infertility, and may even cause the sperm to fail to conceive successfully, or even if conception is successful, it may easily cause miscarriage. Therefore, the quality of sperm depends on whether a healthy baby can be born. Here are some methods of judgment.

Healthy semen is the foundation for men to conceive. In addition to sex, some signs in daily life can also show the health of a man's semen.

A man's appearance can tell whether his sperm is good or bad

Not every man can have a well-defined six-pack, but those with a big belly may have real problems with their semen. Dutch researchers found that men with a waist circumference of more than 40 inches (about 102 cm) had lower sperm concentrations and fewer sperm that moved normally. The researchers believe that carrying too much weight in the abdomen can hinder the release of sex hormones and the production and development of sperm.

Researchers in Spain and Finland found that compared with handsome men, men with average looks have better semen quality. The researchers used the "trade-off hypothesis" theory to explain the reason, that is, the energy invested in reproductive resources by men is fixed, and if a man uses more resources for semen production, then the resources he uses for appearance characteristics will decrease.

Men who love to eat fish have better sperm quality, this is what Harvard University researchers found. The study pointed out that fish has a protective effect on sperm. Men who often eat deep-sea fish such as salmon and tuna have a sperm concentration that is 65% higher than that of ordinary people. The omega-3 fatty acids contained in fish promote the production of sperm.

British scholars have found that men who wear loose underwear have higher sperm motility. Sperm motility is very important. Sperm that swim slowly have difficulty reaching the egg and thus cannot successfully conceive. Loose underwear can lower scrotal temperature and improve semen quality.

Researchers at Harvard University also found that men who exercise regularly have 73% higher sperm concentration than men who do not exercise. This is because regular exercise can prevent free radicals from damaging sperm cells. Researchers also found that compared with men who do not watch TV, men who watch TV for more than 20 hours a week have a 44% lower sperm concentration.

Although women find men with lower-pitched voices more attractive, men with soft, calm voices have higher semen concentrations. Researchers at the University of Western Australia believe that high testosterone levels can make the voice deeper, but too much testosterone can inhibit sperm production.

In daily life, people who use less plastic containers have better sperm. Danish scholars believe that bisphenol A affects the activity of androgens and estrogens in the epididymis, thereby hindering the normal development of sperm.
