Men who wear boxers have a much higher sperm count, says study

Men who wear boxers have a much higher sperm count, says study

The men involved were aged between 18 and 56 who visited Massachusetts General Hospital between 2000 and 2017 as part of couples seeking fertility treatment. Each provided a semen and blood sample, and answered a questionnaire that asked about the type of underwear they most often wore during the preceding three months.

The study probed the potency of 656 men between 32 and 39 and found that guys who sported boxer shorts had a 25 percent higher concentration of sperm and 17 percent higher sperm count totals.

"These results point to a relatively easy change that men can make when they and their partners are seeking to become pregnant", said lead author Lidia Mínguez-Alarcón, of Harvard.

It's been suggested that 21st Century man is, reproductively speaking, only half the man his grandfather was.

Researchers also found that men who wore boxers had 14 percent lower levels of follicle-stimulating hormone (FSH). They were given the choice of "boxers", "jockeys", "bikinis", "briefs", or "other".

Men who wear tight-fitting briefs have sperm counts that suffer in comparison to men who wear boxers, according to results from the largest study to date on the controversial topic.


Men donning boxers have a higher sperm count, the new study concluded.

"Because of this, we were able to find a potential compensatory mechanism whereby decreased sperm production relating to the type of underwear signals to the hypothalamus to increase secretion of gonadotropin [s], [hormones that act] on the testes and that is reflected by the increased levels of FSH, to try to increase sperm production". They add that for men with fertility problems, loose underwear has been advocated before.

However, researchers noted that none of the sperm counts measured were below the normal range, implying that underwear is not a major factor in pregnancy.

The study strongly also does not prove that there is any connection between tight boxers or underwear and low sperm count.

The full findings are present in the journal- Human Reproduction. "Additionally, the differences in hormone and semen analysis parameters were not different enough to be identified as the primary cause of infertility".
