Hormonal

Lifestyle modification (diet and exercise) restores ovulation and reproductive potential in obese women with PCOS primarily through improved insulin sensitivity and reduced LH, independent of significant weight loss.

If you have PCOS and are struggling with infertility, focus on sustainable diet and exercise changes rather than rapid weight loss. Even small improvements in your diet and activity levels can significantly improve your insulin sensitivity and hormone balance, potentially restoring ovulation and pregnancy chances without needing to lose a large amount of weight.

GoodSupportsHIGH confidence
We conclude that lifestyle modification without rapid weight loss leads to a reduction of central fat and improved insulin sensitivity, which restores ovulation in overweight infertile women with PCOS.
