Temperature-controlled switch activates sperm, is key to fertility
Washington University in St. LouisWashU Medicine researcher Polina Lishko, PhD, a BJC Investigator and professor of cell biology and physiology, has shown in mice that sperm have a temperature-controlled switch that changes their movements and is key to male fertility. The discovery sheds light on why mammals, including humans, have evolved to keep male reproductive organs cooler than their core body temperature.
