How sperm crack the whip
Researchers have identified a key component of the mechanism spermatozoa use to abruptly convert their tail motion from a steady swimming undulation to the whip-cracking snap that thrusts them into an egg. view more (2006-02-09)
Damage to sperm DNA affects older men's chances of fathering children
Damage to DNA in sperm is significantly higher in older men than in those who are younger, according to research presented today (Tuesday 21 June 2005) at the 21st annual conference of the European Society of Human Reproduction and Embryology. view more (2005-06-21)

Publication of consultation document on donor anonymity and British Fertility Society's response
Anonymity of sperm and egg donors has been the subject of increasing debate over recent years. The Department of Health have sought the views of the public and professionals as to whether, and to what extent, information about people who have donated sperm, eggs or embryos should be given to children born as the result of those donations.1,2 The... view more...
