Reproductive aging: biological pathways and potential interventive strategies.

Area of Science:

• Reproductive biology
• Gerontology
• Genetics

Background:

• Reproductive aging is a natural process affecting both sexes, though more recognized in females.
• Female reproductive aging involves follicle depletion and reduced oocyte quality, leading to menopause.
• Male reproductive aging also causes infertility and negatively impacts offspring, despite being less recognized.

Purpose of the Study:

• To review factors contributing to reproductive aging in both females and males.
• To summarize potential interventions for delaying or reversing reproductive aging phenotypes.
• To address the growing concern of increasing pregnancy age and its impact on human fertility.

Main Methods:

• Review of existing literature on reproductive aging in humans and model organisms.
• Analysis of factors such as oxidative stress, mitochondrial dysfunction, telomere shortening, and genetic alterations.
• Synthesis of findings on biological pathways involved in reproductive aging.

Main Results:

• Identified key factors contributing to reproductive aging, including oxidative stress and genetic alterations.
• Highlighted the impact of reproductive aging on fertility and offspring health in both sexes.
• Summarized various interventive strategies explored in scientific studies.

Conclusions:

• Understanding the mechanisms of reproductive aging is crucial for developing fertility preservation strategies.
• Interventions targeting identified factors may help delay or rescue reproductive aging.
• Further research is needed to translate findings into effective clinical applications for extending human fertility.
