[How to assess ovarian reserve in 1999?].
Fertility and results of infertility therapies are submitted to amajor drop in relation with the age of the female patient and her so-called ovarian reserve. Although there is no clear definition of what is exactly the ovarian reserve, the consequence of its decline is a greater difficulty to produce ovocytes with a capacity of becoming living embryos after fertilization. Several tests have been developed to assess the ovarian reserve in order to evaluate the prognosis of spontaneous fertility, the results of infertility therapy and assisted procreation techniques, and to make necessary technical adaptations. Basal determinations of FSH, estradiol and inhibin B at day 3 of the cycle an all reflect the ovarian potential, but only FSH reflects a decline infecundability reliable enough to be used as a screening test. Challenge tests such as the clomiphene citrate, the exogenous FSH or the GnRH challenge tests have the purpose to reveal an exaggerated liberation of FSH or an insufficient secretion of estradiol after stimulation. None of these tests have demonstrated a better sensibility together with a higher specificity and they should be considered as evaluating tools in specific cases only. In conclusion, assessing the ovarian reserve has become a clinical necessity in the following situations: ovulation defect, unexplained infertility, before undergoing ovarian stimulation for assisted procreation, in particular in women above the age of 35. This assessment can be made by determining the basal FSH level on day 3 of a cycle and should be renewed every year.
