Healthy semen is the basis for men to cultivate their next generation. Besides, some signs in daily life can also show the health of male semen. Dutch researchers found that the sperm concentration of men with waist circumference more than 40 inches (about 102 cm) was lower, and the sperm count of normal movement was lower. Researchers believe that abdominal overweight will hinder the release of sex hormones and sperm production and development.
Researchers in Spain and Finland found that the semen quality of flat men was better than that of handsome men. The researchers used the "trade-off hypothesis" theory to explain the reason, that is, the energy invested by men in reproductive resources is fixed. If a man uses more resources for semen generation, his resources for physical characteristics will be reduced.
British scholars found that men who wear loose underwear have higher sperm activity. The motility of sperm is very important. It is difficult for sperm with slow swimming speed to reach the egg, so it is impossible to successfully conceive. Loose underwear can reduce scrotal temperature and improve semen quality.
Researchers from Harvard University found that the sperm concentration of men who insisted on physical exercise was 73% higher than that of men who did not exercise. This is because regular exercise can prevent free radicals from damaging sperm cells. The researchers also found that the sperm concentration of men who watched TV more than 20 hours a week was 44% lower than that of men who did not watch TV.
What are the behaviors of hurting sperm?
Having said so much about the research that male appearance can predict sperm quality, now let's count the countless habits of damaging sperm. Are these statements correct or not?
1. Laptop. Will laptops with wireless network affect sperm quantity and quality? According to the research in the journal Fertility and Non-inertility, the sperm obtained by researchers from 29 men were kept normally and placed under a laptop with wireless connection. As a result, sperm activity under computer decreased and DNA was damaged more. However, according to experts, the impact of computers on sperm needs further study.
2. Take a bath. Long-term high temperature may affect the quantity and quality of sperm, but Dr. Robert Kaufman, a reproductive endocrinologist at Baylor Medical Center, said that the high temperature of the scrotum is indeed related to the reduction of sperm quantity, but moderate bathing does not harm elegance, unless the bathing time is too long every day.
