Eggs, sperm, fertilization and the Juno protein

2pn-Princeton IVFThe mechanism that enables the joining together of eggs and sperm to join together (and form what ultimately results in a baby) has long been a mystery to reproductive science. Now in an article published in the journal Nature, British researchers have described receptor on the surface of egg cells that enable sperm to latch on and fertilize.  This "Juno protein" may be one of the links that enables us to reproduce, and for women who lack this protein, a potential new cause for infertility.
