"It also serves as a foundational dataset for the scientific community to study how human testis and fertility respond to ageing.” Jingtao Guo, also of the University of Utah School of Medicine, said: "Our study reveals potential biomarkers for diagnosis of testis aging and directions for potential treatment of aging-related subfertility. Bradley Cairns, of the University of Utah School of Medicine, said: "Aging may confer a combination of modest molecular changes that sensitize the testis for additional dysregulation, with pronounced dysregulation caused when aging is combined with additional factors such as obesity." Researchers say the results reveal that while ageing may lead to weaker sperm overall, having a high BMI exacerbates the process.ĭr. The study consisted of an analysis of 44,000 cells obtained from autopsied human testes samples from four young men and eight older men. Men with a higher BMI than 30, in the obese range, had sperm that was accelerated in age.Įven fathers who were able to have kids before gaining weight struggled with their reproductive health as they became obese. The FDA said its enforcement efforts wouldn’t target consumers, and would focus instead on manufacturers and sellers of menthol products.Older men are less likely to be able to have children if they are fat, a new study warns.Īging sperm is more likely to be abnormal if the man has a higher body mass index, analysis has found. Under the newly proposed menthol policy, individual smokers wouldn’t be penalized for using menthol cigarettes, and the FDA noted that local law enforcement agencies aren’t empowered to enforce FDA regulations. Officials banned special flavors in 2009 via the Tobacco Control Act but allowed menthol to remain on the market, in part because of concern that legal repercussions might disproportionately impact Black people. Regulators have debated restrictions on menthol products for more than a decade. “The proposed rules represent an important step to advance health equity by significantly reducing tobacco-related health disparities,” Becerra said. Nearly 85 percent of Black smokers use menthol products, compared with 30 percent of white smokers, according to the FDA. Up to 238,000 of the deaths prevented would be among Black smokers, who disproportionately favor menthol cigarettes, the FDA said. Eliminating menthol from cigarettes and cigars could lead to a 15 percent reduction in the number of smokers in the nation within 40 years, resulting in about 654,000 fewer smoking-related deaths. More than 18.5 million smokers 12 years and older in the United States used menthol cigarettes in 2019, the FDA said. Menthol also enhances the addictive properties of nicotine, making it harder for smokers to quit. This flavor additive makes it easier for people to start smoking, and increases the appeal of cigarettes to young people, the FDA notes. Menthol has a cool, minty taste and aroma that can counteract the irritation and harshness of smoking, according to the FDA. “The proposed rules would help prevent children from becoming the next generation of smokers and help adult smokers quit,” said the secretary of Health and Human Services, Xavier Becerra, in an April 28 statement announcing the proposed rule changes.

Food and Drug Administration (FDA) has proposed a ban on sales of menthol cigarettes and all flavored cigars in an effort to curb youth smoking and reduce tobacco-related fatalities, the leading cause of preventable death in the United States.
