Question

What is the relationship between obesity and female fertility?

Options

• Obesity causes hormonal imbalance and impairs ovulation and egg quality

• Obesity enhances fertility through increased estrogen

• Obesity has no effect on reproductive function

• Obesity only affects male fertility

Answer 1

Obesity is listed as a Lifestyle/Environmental cause of female infertility because it causes hormonal imbalances (elevated insulin, altered estrogen and androgens), impairs ovulation, reduces egg quality, and increases miscarriage risk. Weight management is therefore a key intervention for improving fertility outcomes.
