Research led by Dan Baumgardt from the University of Bristol delves into the impact of hot weather on men’s testicles. As the temperatures rise, some men may notice their scrotums appear looser or more pendulous, a phenomenon known as “summer long balls.” This seasonal variation is a natural consequence of the body’s temperature regulation mechanisms. The testes, which contain sperm and produce hormones, are designed to function optimally at a slightly lower temperature than the core body. To achieve this, the testes descend into the scrotum during puberty, where the cremasteric and dartos muscles can adjust their position in response to environmental conditions. In hot weather, the dartos muscle relaxes, allowing the testes to hang lower and increase surface area for cooling. Conversely, when temperatures drop, the muscle contracts, drawing the testes closer to the body for warmth. (Studyfinds)
