Sperm's Inbuilt Homing Device

Sperm cells, bacteria and other microscopic organisms use varying concentrations of chemicals in their environment -- concentration gradients -- to approach or avoid something in a process called chemotaxis. Egg cells release an attractant chemical, which lures the sperm. Researchers have found that a protein in the cell membranes of sperm plays a key role in how they find their way to eggs. The PMCA protein may also help explain how egg cells only interact with sperm from the same species. PMCA may even be a target of drug discovery. https://www.technologynetworks.com/analysis/news/sperms-inbuilt-homing-device-312206?utm_campaign=Newsletter_TN_BreakingScienceNews&utm_source=hs_email&utm_medium=email&utm_content=67786753&_hsenc=p2ANqtz-_H4QzBQpIF2K8-MBfYwYQQa9C2mRA1iMYdhjf27YbV1tgIovu4n7pZTyYOQ3PFTEZdu4WuHsBcPqbJFv3IaRd4bpngqw&_hsmi=67786753
