Congenital hypogonadotropic hypogonadism (CHH) patients with cryptorchidism history usually have poor spermatogenesis outcome, while researches focusing on this population are rare.
This study retrospectively evaluated gonadotropin-induced spermatogenesis outcome in CHH patients with cryptorchidism (n = 40).
One hundred and eighty-three CHH patients without cryptorchidism were served as control.
All patients received combined gonadotropins therapy (HCG and HMG) and were followed up for at least 6 months.
The median follow-up period was 24 (15, 33) months (totally 960 person-months).
Sperm (>0/ml) initially appeared in semen at a median of estimated 24 months (95% confidence interval (CI) 17.8–30.2).
Twenty (20/40, 50%) patients succeeded in producing sperms, and the average time to produce first sperm was 19 ± 8 months.
Five pregnancies were achieved in 9 (5/9, 56%) couples who desired for children.
Compared with CHH patients without cryptorchidism (n = 183), cryptorchid patients had longer median time for sperm appearance in semen (24 months vs.
15 months, P<0.001), lower rate of spermatogenesis (50% vs.
67%, P=0.032), and lower mean sperm concentration (1.9 (0.5, 8.6) million/ml vs.
11.1(1.0, 25.0) million/ml, P=0.006) at the last visit.
In conclusion, CHH patients with cryptorchidism require a longer period for gonadotropin-induced spermatogenesis.
The successful rate and sperm concentration were lower than patients without cryptorchidism.
