Adding a missing protein to in fertile human sperm can ‘kick-start’ its ability to fertilise an egg and dramatically increase the chances of a successful pregnancy, a new study has claimed.
Researchers from Cardiff University have found that sperm transfers a vital protein, known as PLC-zeta (PLCz), to the egg upon fertilisation.
This sperm protein initiates a process called ‘egg activation’ which sets off all the biological processes necessary for development of an embryo. Read full article.
