It has become a recent trend, for women to postpone their childbearing needs beyond the normal years, little realizing the speed of the biological clock or its impact. This being a common practice in the west has now found its way into the Indian scenario slowly but steadily. The demands on women during their peak reproductive years in the form of higher education, better career options and the need for stable relationships, although progressive , seems to be stretching the maternal age to beyond 35 for first pregnancies. What is the impact of age on fertility? For a starter, higher rates of chromosomal abnormalities and the resultant increase in spontaneous miscarriage rates, preterm labour, presence of medical disorders like hypertension and diabetes, a poor response to stimulation in ART cycles, an increase in the multifetal pregnancy rates and last but not the least a higher risk of neonatal morbidity and mortality(Trisomies/Growth Restriction/Respiratory Distress).
Recent literature have cited various methods to predict the ovarian reserve and prognosis for conception in treatment cycles, the most important and easily applicable ones being a day 2/3 serum FSH levels and ultrasound for antral follicle count and ovarian volume. In addition it may be noted that accelerated ovarian follicle depletion by apoptosis precedes natural menopause by 10 to 13 years, so much so that those women who attained menopause by 45 years had already started to lose their potential at age 32 despite regular monthly cycles! This can only be deduced retrospectively and possibly by determining the general age of menopause in the family.
Poor responders can be attributed to this group where a normal FSH, antral follicle count and regular cycles, fail to respond to conventional stimulation regimes. Till date women in their perimenopause, menopause and those suffering from premature ovarian failure only had the option of donor programme or adoption and always fared very well with donor oocyte programme.
But with the current platter of oocyte cryopreservation, ovarian transplantation and stem cell research for use of progenitor cells that could replace the lost oocyte pool or reduce apoptosis rate, |

we will get to keep our cake and eat it too! Well, as infertologists it is our responsibility and ethical commitment to carefully select older women presenting to our fertility clinic, who will most likely be fit physically, emotionally and financially to face motherhood. The mainstay of treatment being counseling and ensuring right choices be it own or donor programme or adoption. Ultimately the outcome of any decision would reflect on the well being of the child and his/her future, so it is not only the doctor but the responsibility of these couples/single women to ponder and make the right choices
