Wearing Boxers May Be Better for Your Sperm Count, Study Says

Boxers or briefs? Researchers from the Harvard T.H. Chan School of Public Health have new findings that may help settle the debate. Men who wear boxers tend to have higher sperm counts and better quality sperm than men who wear tighter underwear, according to a study published Wednesday in the journal Human Reproduction. That finding may warrant a wardrobe change among men actively looking to father a child, says study co-author Jorge Chavarro, an associate professor of nutrition, epidemiology and medicine at Harvard. “It will definitely not harm anyone, and it will probably help the men who are likely to benefit from a small boost in their sperm counts,” Chavarro says. Based on the typical cycle of sperm production, he estimates it would take about three months of wearing boxers, after a period of wearing tighter options, to see sperm levels increase. The study was based on data from 656 men who were part of couples seeking infertility treatment at Massachusetts General Hospital between 2000 and 2017. The men answered questions about their lifestyle habits, including the type of underwear they typically wore, and provided semen samples for analysis. (Some also provided blood samples for hormone testing.) The researchers then compared the results of semen and blood analyses with lifestyle survey responses. The 53% of men who reported typically wearing boxers had roughly 25% higher sperm concentrations, 17% higher total sperm counts and 33% higher motile sperm co...

Genesis, genes and epigenetics of endometriosis-associated infertility, Published online: 18 March 2019; doi:10.1038/s41574-019-0191-9Jae-Wook Jeong and colleagues report that histone deacetylase 3 (HDAC3) is downregulated in the endometrium of women with endometriosis. In addition, they show that the loss of HDAC3 is associated with aberrant hormonal signalling and increased fibrosis in the endometrium and impaired endometrial receptivity.

AbstractUbiquitin-specific protease 26 (USP26) is a deubiquitylating enzyme belonging to the USPs family with a transcription pattern restricted to the male germline. Since protein ubiquitination is an essential regulatory mechanism during meiosis, many efforts have been focused on elucidating the function of USP26 and its relationship with fertility. During the last decade, several studies have reported the presence of different polymorphisms inUSP26 in patients with non-obstructive azoospermia (NOA) or severe oligozoospermia suggesting that this gene may be associated with human infertility. However, other studies have r...

Interestingly, the harmful effect of testicular heat stress on sperm characteristics including nuclear DNA integrity was well characterized; however, the influence of sedentary work on sperm chromatin has not yet been documented. Therefore, our research was designed to examine the potential effects of sedentary ...

(European Association of Urology) Scientists have found that sperm DNA from the testicles of many infertile men is as good as that of ejaculated sperm of fertile men. This may explain a major cause of male infertility and opens the possibility of using sperm taken directly from the testicles of these men; to overcome their infertility.
