25th January 2006 Fertility predictor test launched A test which allows women to predict the rate at which their fertility is declining has been launched today. The test, designed by scientists at Sheffield University, works by measuring the number of eggs in a woman's ovaries and indicating what that level might be like in two years time. It measures the levels of three fertility hormones in the blood and plots the results against average fertility for the woman's age. On the third day of her period, a woman gives a 3ml sample of blood, which is sent off for laboratory testing to measure the levels of the hormones which could indicate the approach ofthe menopause. This is then plotted onto a graph showing the woman's position compared with the average fertility for women of the same age. The test, called Plan Ahead, is only available privately for £179 and not on the NHS. Sheffield fertility expert Professor Bill Ledger, who developed the test kit over five years, said he was confident it was an accurate predictor of fertility and that he hoped it would allow women to plan for the future. "If having family is the most important thing, you're best trying to have babies when you're in your twenties - there's no question that the longer you delay, the bigger your chance of heartbreak," he said. "But I think the reality of modern life is that women in the Western world, for all sorts of good reasons, are putting off starting a family until they are in their thirties." He added, "There is more research going on but this is good enough to do what it says it does - give people a two-year warning that their ovarian reserve is declining." Fertility is known to sharply decline from the age of 35, on average, but some women's ability to have children falls even earlier. One in 100 women have their menopause by the age of 40, but fertility begins to decline a number of years before its onset. However, critics of the test point out that there are a number of complex factors affecting fertility. Dr Susan Bewley, pregnancy specialist at Guy's and St Thomas' Hospital said, "The only reliable test of fertility is actually trying to get pregnant. Test kits are likely to lead to people putting off that process and can give false reassurance. "Couples would be better off spending their money on a candlelit dinner." Clare Brown, chief executive of Infertility Network UK, said the test was a good way of allowing women to make a more informed decision about when to try for a family. But she added, "It is important to realise that whilst Plan Ahead is a valuable test, there are other factors that may cause difficulties in conceiving so it is vital that men and women make sure they are fully informed when making decisions on when to have a family." Dr Allan Pacey, secretary of the British Fertility Society, said, "This will be a useful test for those women who want to be able to better plan when they want to have their children. "However, they should remember that female fertility declines with age and that there are dangers of leaving things too late in life. "IVF doesn't work for everyone and there are dangers in thinking it can." Where to next?
