Introduction

Obesity has become a rising health concern in India. Beyond its impact on heart health, diabetes, and joint problems, obesity also plays a major role in Male and female infertility. Studies show that excess body fat disrupts hormone balance, reduces sperm quality, and contributes to conditions like PCOS (Polycystic Ovary Syndrome) in women. For couples planning a family, understanding how obesity affects fertility is crucial. The good news: lifestyle changes, medical support, and professional guidance can improve outcomes.

Understanding the Link Between Obesity and Fertility

  • In men, obesity lowers testosterone and increases estrogen, leading to poor sperm production.
  • In women, obesity is strongly associated with PCOS, irregular periods, and ovulation issues.
  • Both genders face increased risk of pregnancy complications due to obesity.

Causes: How Obesity Impacts Reproductive Health

  1. Hormonal Imbalance – Fat tissue increases estrogen levels, disturbing the reproductive cycle.
  2. PCOS in Women – A common obesity-related disorder that leads to infertility.
  3. Low Sperm Count in Men – Obesity reduces sperm motility and quality.
  4. Insulin Resistance – Affects ovulation and increases miscarriage risk.
  5. Sleep Apnea & Stress – Indirectly lower fertility through poor hormone regulation.
