Cannabinoid receptor activates spermatozoa

During fertilization, a sperm must first fuse with the plasma membrane and then penetrate the female egg in order to penetrate it. To this end, sperm cells go through a process known as the acrosome reaction which is the reaction that occurs in the acrosome of the sperm as it approaches the egg. In the lab, this so-called acrosome reaction is considered a test for analysing the ability of semen to accomplish fertilisation. A receptor for an endogenous cannabinoid plays a crucial role in this process. A team of biologists from Bochum and Bonn, headed by Prof Dr Dr Dr
