Research progress on mitochondrial damage and repairing in oocytes: A review

Area of Science:

• Reproductive Biology
• Cellular Biology
• Mitochondrial Medicine

Background:

• Oocytes, the female germ cells, are vulnerable to environmental, metabolic, and pathological stressors.
• Mitochondria are key organelles affected by these stressors, impacting oocyte development and function.
• Mitochondrial dysfunction is a significant contributor to diminished oocyte quality and female infertility.

Purpose of the Study:

• To review the impact of various factors on mitochondrial damage during oocyte development.
• To discuss strategies for mitigating mitochondrial damage in oocytes.
• To provide a foundation for enhancing female fertility through mitochondrial protection.

Main Methods:

• Literature review of factors affecting oocyte mitochondria.
• Analysis of the relationship between mitochondrial damage and oocyte quality.
• Discussion of antioxidant and therapeutic approaches for mitochondrial repair.

Main Results:

• Environmental, metabolic, aging, and pathological factors induce mitochondrial damage in oocytes.
• This damage disrupts ATP production, redox balance, and apoptosis regulation.
• Mitochondrial damage is directly linked to reduced oocyte quality and female infertility.

Conclusions:

• Protecting oocyte mitochondria from damage is crucial for maintaining female fertility.
• Antioxidant therapies can prevent or repair mitochondrial damage, improving reproductive outcomes.
• Further research into mitochondrial protection strategies may offer new avenues for fertility treatments.
