It is not an uncommon question encountered by a routine Gynaecologist by Women in her 30s who wants to balance between a career and a family.Do we have an answer?Up to an extent yes but not certainly with a hundred percent certainty.
There is a hormone called AMH -Anti mystery hormone :) .Well this anti mystery hormone is actually called anti Mullerian Hormone.This AMH gives an idea of your ovarian reserve.It would not give any idea of the quality of hormone remaining but will comment on the quantity of ovarian follicles remaining at that particular time.Higher the AMH more is your ovarian reserve and probably you can wait few more years and vice verse.
AMH has other uses too.It is measured by Infertility specialist world over as the baseline which helps us in deciding the starting dose for Gonadotrophins for stimulating an IVF cycle or for that matter even IUI cycle.
