Melbourne: Australian fertility experts havedeveloped a technology to magnify human sperm by 7300 times its normal size in a bid to help childless couples to conceive.Fertility specialists in Australia were able to magnify human sperm to 15 centimetres long with heads as big as 10? pieces, about 18 times larger than they had ever seen givingthem clearest picture yet of which sperm are most capable of fertilisation, according to newspaper `The Age`.The technique is being used to help men whose partners have experienced repeated infertility or miscarriages due to DNA damage to sperm or significant morphology problems, such as sperm with oddly shaped or multiple heads. Some sperm appear normal when magnified 400 times, the largest magnification previously available, but when blown up 7300 times, it is clear their heads have tiny holes in them where the chromatin, or DNA, is housed. This makes them unableto fertilise an egg.Medical director of IVF Australia, Peter Illingworth said that the imagery was a breakthrough for couples struggling with sperm problems.
