Underwear for men

Abstract

An underwear for a male with mesh strips or a hole to ease air flows around wearer's scrotum and groin regions to lower temperature and humidity. Apart from traditional men's underwears, there are mesh strips covering or crossing on wearer's groin, buttock channel and scrotum. When wearer in a standing or walking or running position with loose outerwear, the air around scrotum can flow naturally to lower the temperature and humidity of scrotum, and then increase the productivity of spermatogenesis and sex hormones.
