News | Ketogenic Diet Helps Women With PCOS Restore Menstrual Cycles and Improve Pregnancy Rates
A recent study found that a ketogenic diet may help women with polycystic ovary syndrome (PCOS) restore regular menstrual cycles and significantly improve pregnancy rates.
Published in Frontiers in Nutrition, the study found that 55.6% of participants who wanted to conceive became pregnant. Menstrual regularity also improved significantly, suggesting potential fertility benefits for women with PCOS.
Background
PCOS affects about 20% of women of reproductive age and is a major cause of infertility due to irregular ovulation. Obesity, affecting up to 75% of patients, is closely associated with PCOS and can worsen hormonal imbalance and ovulatory dysfunction. Diet and treatments that improve insulin sensitivity may support fertility, and ketogenic diets have attracted attention for their effects on weight and metabolic health.
Results
The study followed 30 women with PCOS in a weight-management program. Their average age was 31 and average body mass index (BMI) was 43.4. After 6 months on a ketogenic diet, 92% had resumed normal menstrual cycles; after 15 months, all participants had regular cycles. Among 18 women wishing to conceive, 55.6% became pregnant, and 63% conceived within 12 months.
Some women used ovulation-induction medication or metformin, but outcomes did not differ significantly by medication use. Although weight loss supported fertility, improved insulin resistance may have been the key factor behind higher pregnancy rates.
Conclusion
The study suggests that a ketogenic diet may restore menstrual cycles and improve fertility in women with PCOS. However, it was small and did not fully assess long-term effects or compare other diets. Larger studies are needed to confirm long-term fertility effects and investigate underlying mechanisms.
