The inverse correlation between age and female fertility in later reproductive life is argued to motivate family planning well before having reached 35 years of age.[23] Mapping of a woman's ovarian reserve, follicular dynamics and associated biomarkers can give an individual prognosis about future chances of pregnancy, facilitating an informed choice of when to have children.[24] Notably, a higher level of anti-Müllerian hormone when tested in women in the general population has been found to have a positive correlation with natural fertility in women aged 30–44 aiming to conceive spontaneously, even after adjusting for age.[25] Thus, AMH measurement is helpful to determine which women may need to conceive at an earlier age, and which women can potentially wait.[26]
