Introduction:
This prospective study investigated the efficacy of a gonadotropin-releasing hormone agonist (LH-RHa) in restoring defective mini-puberty.
Materials And Methods:
Boys with isolated bilateral cryptorchidism and defective mini-puberty were randomly divided into two groups. The "surgery only" group underwent a second orchidopexy without hormonal treatment (control). The "LH-RHa" group received LH-RHa therapy followed by a second orchidopexy. The number of Ad spermatogonia and the total germ cell count per tubule (S/T) were analyzed.
Results:
Five boys were included in each arm. In the LH-RHa group, the median S/T increased from 0.11 to 0.42, p=0.04. In the surgery only group, the median S/T did not change. In the surgery only group, none of the testes had Ad spermatogonia. In contrast, in the LH-RHa group, all testes completed the transition from gonocytes to Ad spermatogonia (p=0.008).
Conclusions:
Treatment with LH-RHa was effective in rescuing defective mini-puberty in boys with bilateral cryptorchidism.
