New fertility technique uses fewer embryos
London | August 13, 2008 12:01:13 AM IST
A new fertility technique called vitrification has resulted in the birth of a healthy baby girl in Britain. Vitrification is an improved method of embryo storage in which embryos are flash-frozen in liquid nitrogen along with an antifreeze, The Times of London reported Tuesday. Traditional methods of freezing embryos have a 50 percent to 80 percent success rate, compared to a 98 percent success rate for embryos frozen with the new method. Lyndon Miles, head of embryology and andrology at IVF Wales, said vitrification could persuade more couples to use just one embryo and cut the multiple birthrate from one in four to one in 10, the British newspaper said.
