As I am sure you are aware a woman's fertility starts to decline after she gets to 30 but what you probably did not know is that the hormone F.S.H. (follicle stimulating hormone) is intimately involved with a woman's fertility and rising levels tend to be associated with reduced fertility. F.S.H. is the hormone that maintains the regular function of your ovaries and sex hormones it is a useful aid to assessing your fertility. This test will indicate whether your F.S.H levels are raised or not - a positive test result suggests your fertility is reduced and we recommend that you see your doctor to discuss the results and perhaps have more tests done.
