4 / 9 Rumored Sperm Killer: Hot Tubs
While it's true that the heat related to hot tub exposure might affect sperm count and sperm quality over time, you probably don't need to worry about a hot tub being a sperm killer or leading to infertility unless you're spending hours in it every day, said Robert Kaufmann, MD, a reproductive endocrinologist at Baylor All Saints Medical Center in Waco, Texas. "There has been an association with hot tubs and heat in the scrotal area and decreased sperm counts, although moderate exposure to hot tubs does not appear to create a problem," he explained. Just avoid prolonged exposure.
