Objective: To compare human menopausal gonadotropin (hMG) and recombinant follicle-stimulating hormone (rFSH) with respect to successful spermatogenesis and pregnancy outcomes in patients with congenital hypogonadotropic hypogonadism (CHH).
Material and methods: This retrospective study included a total of 112 male patients with CHH. Of these, 70 were to receive treatment with hMG and 42 with rFSH following the hCG administration.
Results: The average age at diagnosis was 27.9 (range, 15–51) years. The baseline luteinizing hormone (LH), follicle-stimulating hormone (FSH), and testosterone levels were 0.53±0.77 IU/L, 0.63±0.61 IU/L, and 1.10±1.90 ng/dL, respectively. Following the combined hormonal treatment, 85.7% (96/112) of patients had sperm detected in ejaculate samples. In the hMG group, the mean baseline of a testicular size was slightly lower than in the rFSH group (5.0±3.5 mL and 5.3±3.9 mL), whereas these differences were not statistically significant (p=0.364). The mean baseline age, level of FSH, LH, and testosterone also showed no significant difference between the two treatment options. The rate of successful spermatogenesis was similar (85.7%) in both groups, while the pregnancy rates of patients who underwent hMG and rFSH treatments were 38.6% (n=27) and 51.2% (n=21); however, these differences were not statistically significant (p=0.314). No patients developed severe effects during the treatment period.
Conclusion: Successful spermatogenesis and pregnancy rates with hMG and rFSH are similar.
