Study: Wearing a kilt could make your sperm stronger

Temperature affects how much sperm a man makes, so there’s been speculation that the freedom offered by a kilt can increase production. Turns out that that at least could be right: a new metastudy says wearing a kilt “likely produces an ideal physiological scrotal environment, which in turn helps maintain normal scrotal temperature, which is known to be beneficial for robust spermatogenesis and good sperm quality.”

… We know sperm fares better in lower temperatures, and some researchers have suggested that restrictive clothing could negatively affect sperm production. …

The author hypothesizes that, based on past findings about temperature and sperm production, a kilt, specifically one worn in the undergarment-free “regimental” style, would be an ideal environment for sperm production.
