Abstract
PURPOSE OF REVIEW: In the past few decades, women have been intentionally delaying pregnancy and ovarian aging has become one of the most detrimental factors of pregnancy achievement. This review will discuss contemporary methods of ovarian aging assessment and present an overview of current management strategies. RECENT FINDINGS: Antimullerian hormone (AMH) and antral follicle count (AFC) seem to be the most reliable predictors of ovarian aging appraisal. Nevertheless, they have not been shown to predict pregnancy achievement in assisted reproduction. Heritability has a high impact on ovarian aging. Employing several genetic approaches, it is now being widely investigated, but the task is far from being accomplished. Although multivariate models have not been proven to be superior to AFC, new data support the notion that chronological age and genetic markers inclusion may increase their reliability. Several strategies have been suggested to treat ovarian aging in assisted reproductive technology (ART) settings. None of the stimulation protocol manipulations have been found to be advantageous and individualization of treatment is still recommended. Ovarian priming by different androgen preparations has been shown to be promising but more randomized controlled trials are needed to support these findings. Except for oocyte donation other ART strategies have not shown a convincing benefit for ovarian aging. The new development of oocyte vitrification may well introduce opportunities for fertility preservation to women at risk of ovarian aging. SUMMARY: Proper assessment and detection of ovarian aging, employing current or developing predictors of ovarian reserve, especially genetic tests, may enable health providers to recommend, at appropriate biological time, early pregnancy achievement or fertility preservation in women at risk.
