HONG KONG (AFP) - Hong Kong scientists said on Friday they have discovered a molecule that binds human sperm to an egg, in a breakthrough which offers new hope for infertile couples. The study by researchers at the University of Hong Kong (HKU) found a key molecule on the coating of the human egg, called sialyl-LewisX (SLeX), which acts as a binding agent to help the sperm and egg stick together. 'This research provides an enlightening answer to a basic important question and human fertilisation - how does a sperm bind to an egg?' William Yeung, one of the researchers, told AFP. 'But this is only a first step that will lead to more discoveries,' said Mr Yeung, who is also a professor at HKU's department of obstetrics and gynaecology.
