Protective Role of Physical Activity and Antioxidant Systems During Spermatogenesis

Area of Science:

• Reproductive Biology
• Oxidative Stress Research
• Exercise Physiology

Background:

• Oxidative stress, characterized by excessive reactive oxygen species (ROS) production, impairs sperm function and male fertility.
• High ROS levels lead to genomic damage, lipid peroxidation, inflammation, and reduced seminal parameters, contributing to irreversible cellular damage and infertility.

Purpose of the Study:

• To elucidate the mechanisms of ROS generation and their physiological/pathophysiological roles in the male reproductive system.
• To review the current understanding of how physical activity protocols impact male reproductive health and associated molecular pathways.

Main Methods:

• Literature review focusing on oxidative stress, male reproductive function, and physical activity.
• Analysis of studies investigating the effects of various physical activity regimens on seminal parameters and molecular markers.

Main Results:

• Physical activity demonstrates potential in mitigating ROS-induced damage through improved antioxidant capacity and modulation of inflammatory responses.
• Specific PA protocols may positively influence sperm quality and counter detrimental effects of oxidative stress on male reproductive health.

Conclusions:

• Physical activity emerges as a promising non-pharmacological intervention to address oxidative stress-related male infertility.
• Further research into optimized PA strategies is warranted to fully leverage its benefits for male reproductive health.
