Female Fertility Test 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 and is a useful aid to assessing your fertility. This test is especially useful for women with irregular cycles and women aged 30 or over. 3 tests are included and if all 3 test results are positive it is an indicator of reduced fertility. If you are over 40 then this test is also useful to determine if you are pre-menopausal. Any positive result should be discussed with your doctor.
