Abstract
Objective: This study aimed to assess the effects of metformin (MET) monotherapy versus a combination of semaglutide and MET on weight, metabolism, reproductive function, and inflammatory markers in women with polycystic ovary syndrome (PCOS).
Methods: A total of 100 overweight or obese women with PCOS diagnosed according to the Rotterdam criteria were randomly assigned to two groups: MET (1000 mg twice daily [BID] for 16 weeks) and combination therapy (COM) (1000 mg MET BID plus 1- mg semaglutide once weekly [QW] for 16 weeks). Primary outcomes, assessed at Week 0 and Week 16, included changes in anthropometric measures related to obesity, while the secondary outcomes included alterations in reproductive hormone levels, glucose and lipid metabolism, and C-reactive protein (CRP) levels, Between Weeks 16 and 40, all participants received metformin monotherapy (1000 mg BID) to evaluate pregnancy outcomes.
Result: A total of 80 participants (80%) completed the study. After 16 weeks of intervention, the COM group exhibited significantly greater reductions in body weight, BMI, and waist-to-hip ratio (WHR) compared to the MET group (all P < 0.01). The COM group experienced an average weight loss of 6.09 ± 3.34 kg, while the MET group lost only 2.25 ± 4.27 kg. The COM group also demonstrated greater improvements in testosterone (TEST), Chinese visceral adiposity index (CVAI), and CRP levels compared to the MET group. Additionally, the COM group showed higher rates of menstrual cycle recovery than the MET group. From weeks 16 to 40, the COM group demonstrated a significantly higher natural pregnancy rate than the MET group (35% vs. 15%, P < 0.05).
Conclusion: Compared to MET monotherapy, combination therapy with semaglutide and MET significantly reduced body weight, improved insulin resistance, decreased inflammatory markers, alleviated and menstrual irregularities and increased natural pregnancy rates in overweight/obese women with PCOS.
