Fertility: Gentlemen, here’s why underpants are to be banned
In a recent study, researchers at an American university revealed that the choice of underwear would be even more important because it has a direct impact on fertility in a man. The skintiest ones would affect the production of spermatozoa.
The causes of infertility are diverse and varied But men who want to become a father would be better off paying attention to the choice of their underwear. Indeed, an American study published on August 8, 2018 in the journal Human Reproduction showed that loose underwear would have a positive impact on sperm production, compared to those that are more snug.
Higher Sperm Concentration Among Fans of Underpants
To reach this conclusion, 656 men performed spermograms (semen analysis) between 2000 and 2017. In the procreation service of the Massachusetts General Hospital in Boston. They also had to fill out questionnaires asking them to fill in the type of underwear they wore most often. The result was unequivocal: 53% of men said they usually wear underpants. They had a sperm concentration 25% higher than those who favored underclothes tighter (short or long boxer briefs, etc.).
In addition, the study found that men who preferred to wear underwear near the body secreted more follicle-stimulating hormone (FSH), which stimulates the formation of spermatozoa. This mechanism will compensate for a temperature too high for the testicles. Now, we know that heat weakens the spermatozoa. This is also the principle of heated underpants, method of male contraception.
What is the cause of male infertility?
It is estimated that infertility can come in 30% of women’s cases, in 30% of men, in 30% of both men and women. And in 10% of an unknown cause. Infertility is not to be confused with infertility: according to IVI, being infertile means “an inability to conceive and generate offspring after a year of regular sexual intercourse” and can therefore be transient. While being sterile is defined by “the inability for an individual or a couple to naturally conceive a child.”
The most common causes of male infertility may be intrinsic (complete absence of spermatozoa, too few functional sperm, insufficient motility of sperm, excessive sperm count) or extrinsic. In this case, environmental factors are to be taken into account such as tobacco, pollution, alcohol, stress or chemicals. Drug, hormonal or surgical treatments exist to treat male infertility.
