• To compare the effects of combined gonadotropin and pulsatile gonadotropin-releasing hormone (GnRH) therapy on spermatogenesis in patients with pituitary stalk interruption syndrome (PSIS). Male patients with PSIS (N = 119) were retrospectively studied. Patients received pulsatile GnRH therapy (N = 59) were divided into response and poor-response groups based on luteinizing hormone (LH) levels after 1-month treatment with a cutoff value of 1 or 2 IU/L. Participants with gonadotropin therapy were divided into human menopausal gonadotropin (hMG)/human chorionic gonadotropin (hCG) group (N = 60), and patients with pulsatile GnRH therapy were classified into GnRH group (N = 28) with treatment duration ≥6 months. The overall success rates of spermatogenesis for hMG/hCG and GnRH therapy were 51.67% (31/60) vs 33.90% (20/59), respectively. GnRH group required a shorter period to induce spermatogenesis (8 vs 15 months, P = .019). hMG/hCG group had higher median total testosterone than GnRH group [2.16, interquartile range(IQR) 1.06-4.89 vs 1.31, IQR 0.21-2.26 ng/mL, P = .004]. GnRH therapy had a beneficial effect on spermatogenesis compared to hMG/hCG therapy (hazard ratio 1.97, 95% confidence interval 1.08-3.57, P = .026). In patients with pulsatile GnRH therapy, compared with the poor-response group, the response group had a higher successful spermatogenesis rate (5.00% vs 48.72%, P = .002) and higher median basal total testosterone (0.00, IQR 0.00-0.03 vs 0.04, IQR 0.00-0.16 ng/mL, P = .026) with LH = 1 IU/L as the cutoff value after 1-month pulsatile GnRH therapy. Pulsatile GnRH therapy was superior to hMG/hCG therapy for spermatogenesis in patients with PSIS. Earlier spermatogenesis and higher concentrations of sperm could be obtained in the GnRH group if patients received therapy over 6 months.
