Researchers identify protein FER1L5 as essential for male fertility in mice

Fertilization is the union of two cells: an egg and a sperm. Before the egg and the sperm fuse, an event known as the "acrosome reaction" needs to occur in the sperm. Now, a team from Osaka University has identified a protein called FER1L5 that is es.....»»
