Area of Science:

  • Reproductive Endocrinology
  • Exercise Physiology
  • Human Metabolism

Background:

  • The reproductive system's function is closely linked to the body's energy balance.
  • Physical activity influences energy balance, potentially affecting reproductive health.
  • Current physical activity guidelines necessitate understanding its reproductive consequences.

Purpose of the Study:

  • To explore the multifaceted effects of physical activity on the human reproductive system.
  • To highlight the impact of energy balance extremes on reproductive disorders.
  • To identify the need for applied research on energy availability's role in human reproduction.

Main Methods:

  • Review of existing literature on physical activity, energy balance, and reproductive function.
  • Analysis of reproductive disorders associated with chronic energy excess and deficiency.
  • Identification of potential interventions for mitigating physical activity-induced reproductive disruptions.

Main Results:

  • Both energy excess and deficiency, influenced by physical activity levels, are linked to reproductive disorders.
  • Reproductive issues include menstrual irregularity, anovulation, PCOS, infertility in women, and erectile dysfunction, altered spermatogenesis in men.
  • Laboratory findings suggest potential for prevention or reversal of reproductive disruptions through lifestyle adjustments.

Conclusions:

  • Physical activity profoundly impacts reproductive health through its effects on energy balance.
  • Reproductive disorders arise from chronic energy imbalances, necessitating further investigation.
  • Applied research is critical to confirm reversibility and elucidate mechanisms of energy regulation in human reproduction.
