A new blood
test that can predict fertility in women planning to delay pregnancy is being
developed by researchers.
A team of
Australian and Dutch scientists have come up with a model of a test that uses
hormone levels to estimate when a female is likely to start menopause that
would help women to count back a decade to when their natural fertility will

examined the levels of anti-Mullerian hormone (AMH) in the blood of a group of
healthy fertile women that reflected the number of small follicles, present in
a woman's ovaries and needed for the supply of eggs for ovulation.
The team used this data to build a model of
age-related change in AMH levels and then predict the age of menopause via a
critical AMH threshold level.
