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.
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.
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.
在过去几十年中,女性一直有意推迟生育,而卵巢衰老已成为妊娠成功的最不利因素之一。本文将讨论当前的卵巢衰老评估方法,并概述当前的管理策略。
抗苗勒管激素(AMH)和窦卵泡计数(AFC)似乎是卵巢衰老评估最可靠的预测指标。然而,它们并不能预测辅助生殖中的妊娠成功率。遗传因素对卵巢衰老有很大的影响。目前,人们广泛采用多种遗传方法进行研究,但这项工作远未完成。尽管多变量模型尚未被证明优于 AFC,但新数据支持这样一种观点,即纳入实际年龄和遗传标志物可能会提高其可靠性。已经提出了几种策略来治疗辅助生殖技术(ART)环境中的卵巢衰老。尚未发现任何刺激方案的调整具有优势,仍然建议个体化治疗。不同雄激素制剂的卵巢预刺激已被证明是有前途的,但需要更多的随机对照试验来支持这些发现。除了卵母细胞捐赠外,其他 ART 策略并未显示对卵巢衰老有明显的益处。卵母细胞玻璃化的新发展可能为有卵巢衰老风险的女性提供生育力保存的机会。
通过使用当前或正在开发的卵巢储备预测指标(特别是遗传检测),正确评估和检测卵巢衰老,可以使医疗保健提供者在适当的生物学时间内,建议有生育风险的女性尽早实现妊娠或进行生育力保存。
