Summary

Polycystic ovary syndrome (PCOS) is a common gynecological endocrine disease and a major cause of anovulatory infertility in reproductive-aged women. From 2010 to 2020, it was found that the prevalence of PCOS in reproductive-aged women in China reached 7.8%, an increase of 65% over 10 years ago. Many of them are overweight or obese. Weight loss including diet modifications can significantly reduce reproductive and metabolic disorders of PCOS and is recommended as a first step in the treatment of overweight or obese women with PCOS. Many weight loss programs have been proposed, including calorie-restriction diet (CRD) intervention. Whether CRD intervention prior to ovulation induction therapy could improve live birth rates in overweight/obese PCOS women has not been illustrated.

Conditions

  • Polycystic Ovary Syndrome

Interventions

BEHAVIORAL

CRD

During the initial 8 weeks of the trial, polycystic ovary syndrome (PCOS) patients are instructed to follow a diet of 1200 to 1500 kcal per day supervised by dietitians. The CRD includes a combination of 40 to 55% of calories from carbohydrates, 15 to 20% from protein, and 20 to 30% from fat; this regimen represented approximately 75% of the participants' daily caloric intake at baseline. All the participants receive dietary counseling daily during the trial.

DRUG

Metformin

After randomization, patients entering the metformin group will be given 1500 mg daily (bid/tid) metformin and regular diets as control. Participants allocated to the control group are followed by the conventional approach (usual care) based on regular visits respecting the usual schedule dictated by the rules of general practice.
