If you are underweight, your body often feels hungry, causing the reproductive system to shut down. Both men and women with a body mass index below 20 generally lead to low fertility, with overweight women having slightly stronger fertility than overweight men. Even slightly overweight men with a body mass index of 25 will have a 22% decrease in sperm count compared to normal weight men of the same age. For women, obese women with a body mass index above 30 may have a significant halving in fertility. So what are the methods to improve semen quality?
Avoiding sexually transmitted infections
Sexually transmitted infections usually have few symptoms, and their damage is not detected until couples attempt to conceive. Especially with the increase of chlamydia infection, there are 10% of cases where the damage caused by chlamydia infection to the fallopian tubes is enough to cause infertility in women without obvious symptoms. Women aged 16 to 24 are prone to infection with chlamydia, but they tend not to have children at this age group, so it was not until many years later that they first became aware of being infected with chlamydia
Pay attention to caffeine intake
Excessive caffeine can increase the risk of miscarriage, although it is not yet clear how much is excessive. A study published in the New England Journal of Medicine by the National Institutes of Child Health and Human Development, a subsidiary of NIH in the United States, found that women who drink 5 or more cups of coffee a day are twice as likely to miscarry as women who drink less coffee. The study also showed that caffeine may enhance the side effects of alcohol. Young people drink too many acidic drinks containing caffeine and sugar every day, which not only leads to weight gain but also easily leads to infertility.
Keep cool
Heat is not conducive to sperm production, and it is evident that men's testicles have dropped to such a vulnerable location, which makes it a reality. The ideal temperature is 3 to 4 ℃ lower than body temperature. Any temperature increase will affect sperm count, and every 1 ℃ increase will cause a sharp decrease of 40%. Scientists speculate that overheating can explain the low sperm count of men working in positions such as taxi drivers and long-distance truck drivers: carefully placed temperature monitors show a 2.2 ℃ increase in scrotal temperature within 2 hours of sitting in the car.
