Obesity, fat distribution and infertility.

Area of Science:

• Endocrinology
• Reproductive Medicine
• Metabolic Health

Background:

• Obesity, particularly abdominal obesity, is linked to impaired fertility in both sexes.
• Hormonal imbalances, including hyperandrogenism in women and hypotestosteronemia in men, are key mechanisms.
• Obesity contributes to polycystic ovary syndrome (PCOS) and associated metabolic/cardiovascular issues.

Purpose of the Study:

• To explore the impact of obesity on reproductive health and hormonal function.
• To investigate the role of obesity in PCOS pathophysiology.
• To assess the benefits of weight loss on fertility and related comorbidities.

Main Methods:

• Review of existing literature on obesity, hormonal disorders, and fertility.
• Analysis of the relationship between obesity phenotypes and sex hormone metabolism.
• Evaluation of the effects of weight loss interventions on reproductive outcomes.

Main Results:

• Obesity disrupts sex hormone secretion and metabolism, leading to infertility.
• Abdominal obesity is associated with relative hyperandrogenism in women and hypotestosteronemia in men.
• Weight loss improves hormonal abnormalities, fertility rates, and erectile dysfunction.

Conclusions:

• Obesity-induced hormonal dysregulation significantly impairs fertility in both sexes.
• Weight loss is a crucial therapeutic strategy for improving reproductive health and managing obesity-related comorbidities.
• Lifestyle interventions promoting weight loss are effective for enhancing fertility and treating erectile dysfunction in obese males.
