There is not much difference between briefs and boxers.

Many people believe that compared with boxer briefs, wearing briefs will increase the temperature of the scrotum and damage sperm. There is actually no need to worry about this. In 1998, New York University conducted a study and found that no matter what kind of underwear you wear, the impact on the scrotum is similar. Experts suggest that you don’t need to put too much thought into choosing the style of underwear. Instead, you should allow your scrotum to be ventilated and breathable.

Don’t put your laptop on your lap.

A 2005 New York University study found that using a laptop on your knees for a long time will significantly increase the scrotal temperature. However, scientists are still studying whether radio waves emitted by electronic devices such as mobile phones or music players have adverse effects on sperm. The safer way is to try not to keep them in your pants pockets for a long time.

Hot baths are a big no-no.

Hot baths and saunas are both "murderers" that will definitely affect the quantity and quality of sperm. Generally, once a week is a more appropriate frequency.

Obesity.

The impact of overweight on testicular function is mainly reflected in two aspects: First, obese people will convert more testosterone into estradiol, thus affecting the number and quality of sperm; on the other hand, the fat near the testicles Excessive tissue thickness can also cause scrotal temperature to rise. Therefore, if you want good sperm quality, it is imperative to lose weight.

Narcotics.

Some studies have shown that drugs such as anesthetics can damage male endocrine, and long-term use of painkillers can also produce such side effects. Therefore, even over-the-counter medications should be taken with caution.

Eating red meat does not affect sperm quality.

Researchers analyzed multiple previous trials and found no clear evidence to support a link. But your best option is to eat more fish.

Ageing.

As age increases, the quantity and quality of male sperm will decrease. If the parents are older, the risk of the newborn having Down syndrome and schizophrenia increases. But overall, the impact of aging on men is not as great as on women, and men in their seventies or eighties can still be fathers.
