Protocols need?to be developed in ART treatments for obese and overweight women. Objectives: To investigate the effect of recombinant luteinizing hormone (rLH) addition to recombinant follicle stimulating hormone (rFSH) on treatment outcomes?in assisted reproductive technologies (ART) cycles in obese and overweight women without polycystic ovary syndrome. Methods: This retrospective cohort study was carried out in Kocaeli University Faculty of Medicine, Assisted Reproductive Techniques Clinic between January 2016 and March 2019. To analyze the impact of rLH addition to rFSH in GnRH antagonist cycles in overweight and obese, the patients were divided into four groups according to body mass index (BMI) and gonadotropin type;Group 1: patients with BMI ≥ 25 stimulated with rFSH alone (n: 37), Group 2: patients with BMI ≥ 25 stimulated with rFSH + rLH (n: 37), Group 3: patients with BMI between 18.5 - 24.99 stimulated with rFSH alone (n: 33), Group 4: patients with BMI between 18.5 and 24.99 stimulated with rFSH + rLH (n: 30). Patients with polycystic ovary syndrome were excluded. Results: Basal LH levels were found to be significantly lower in obese and overweight patients compared to normoweight patients (p = 0.01). Grade 1 embryo ratio in obese and overweight patients was higher in rLH added obese group than in group LH not included (64.9%, p = 0.005). Ongoing pregnancy rates (OPR) in obese and overweight patients were significantly higher in rLH added group compared to rFSH only group (43.2% vs 18.9% respectively, p = 0.044). However, OPR did not differ significantly in rLH added and rFSH only groups in normoweight patients (p = 0.588). Conclusion: This study has shown that obese and overweight non-PCOS patients have lower endogenous LH levels. It has also shown that rLH supplementation in GnRH antagonist cycles in obese and overweight women improves embryo quality and ongoing pregnancy rates. However rLH addition to rFSH doesn’t seem to have a value in normoweight patients.展开更多
