In a society where women often want successful careers and equal opportunities to men, the early nature of ovarian aging often forces women to make difficult life choices between career and family development. Fertility in women begins to decline after the age of 37 years and it is rare for pregnancies to occur after 45. This reproductive decline in women is inevitable and culminates in menopause, which is a major driver of age-related diseases. In a world where biomedical advances are leading to modifiable biological outcomes, it is time to focus on mitigating female reproductive senescence to maintain fertility and preserve age-related hormonal functions, with the goal of providing increased life choices and enhancing healthspan. To date, reproductive longevity research remains an understudied field. More needs to be done to unravel the biology of the ovarian follicles, which are the functional units of reproductive lifespan and are comprised of cell types including the oocyte (female gamete) and a group of specialized supporting somatic cells. Biological attempts to maintain the quality and quantity of follicles in animal models through manipulating pathways involved in aging can potentially prolong female reproductive lifespan and healthspan. Here, we summarize the molecular events driving ovarian aging and menopause and the interventional strategies to offset these events. Developing solutions to female reproductive senescence will open doors to discover ways to enhance true healthy longevity for both men and women.
在一个女性通常希望拥有成功的事业和与男性平等的机会的社会中,卵巢衰老的早期本质常常迫使女性在职业和家庭发展之间做出艰难的生活选择。女性的生育能力在 37 岁后开始下降,45 岁后很少有怀孕的情况发生。女性的这种生殖能力下降是不可避免的,最终会导致绝经,这是与年龄相关疾病的主要驱动因素。在一个生物医学进步导致可改变的生物学结果的世界里,现在是时候关注减轻女性生殖衰老以保持生育能力和保留与年龄相关的激素功能了,目标是提供更多的生活选择和增强健康寿命。迄今为止,生殖寿命延长研究仍然是一个研究不足的领域。需要做更多的工作来解开卵巢卵泡的生物学奥秘,卵巢卵泡是生殖寿命的功能单位,由包括卵母细胞(女性配子)和一组专门的支持体细胞在内的细胞类型组成。通过操纵与衰老相关的途径来维持动物模型中卵泡的质量和数量的生物学尝试可能会延长女性的生殖寿命和健康寿命。在这里,我们总结了驱动卵巢衰老和绝经的分子事件,以及抵消这些事件的干预策略。开发解决女性生殖衰老的方法将为发现如何增强男性和女性真正健康长寿的方法打开大门。
