INTRODUCTION: Considering that the use of aromatase inhibitors in the treatment of infertile men is a new approach and obesity in men is one of the factors affecting infertility, we decided to compare the effect of combined therapy of Human chorionic gonadotropin (HCG) and Letrozole and either of the two methods alone on the spermogram parameters in obese men with idiopathic infertility. MATERIALS AND METHODS: This clinical trial study was performed with the participation of 15 infertile and obese men from 2018 to 2019 in Tabriz (infertility clinics); Patients were randomly divided into three groups; The first group received treatment with Letrozole 2.5 mg daily alone, the second group received treatment with HCG ampoules at a dose of 5000 units twice a week, and the third group received combination therapy with HCG ampoules at a dose of 5000 units twice a week and letrozole tablets at a dose of 2.5 mg daily; The results of testosterone and sperm tests before and after the intervention were evaluated by t-test and linear regression tests in SPSS21 software. A p-value less than 0.05 was considered significant. RESULTS: There was no statistically significant difference between semen indices and hormones studied before the intervention (P < 0.05), while after the intervention there were statistically significant differences between all variables compared to those before the intervention (P < 0.05); Also, the rate of change in the third group was much more favorable than the other two groups. CONCLUSION: The combination of HCG ampules with letrozole tablets compared to the use of these drugs alone improved sperm count, sperm motility, and sperm morphology. AJCEU
