Women's fertility underestimated by 68% in 'highly inaccurate' hormone test

Fertility specialists are reassuring women an updated hormone test is much more accurate than the original, after a study compared the old and new versions

A hormone test used for more than a decade is responsible for highly inaccurate readings of women's fertility, an Australian study has revealed, but fertility specialists are urging women undergoing assisted reproductive treatments not to panic.

The original version of the test, the Anti-Mullerian hormone or "egg-timer" test, was taken off the market three years ago and has not been used since then, having been replaced by updated and much more accurate versions.
