The effects of the administration of gonadotropin-releasing hormone (GnRH) on the increase of testis and prostate volume was monitored by ultrasound in six patients affected by idiopathic hypogonadotropic hypogonadism. A significant increase of testis volume was observed after 90 and 180 days (6.65 versus 3.32 mL, 99.1% net increase and 8.47 mL, 176.8% increase, respectively) of pulsatile GnRH treatment. A similar increase of prostate volume was observed at day 90 (12.67 versus 7.78 mL, 70.3% net increase) and day 180 (14.70 mL, 97.7% increase). The ultrasound monitoring of the modifications of testis and prostate volume may represent a biological assay of the effects of GnRH treatment and offer additional data on the response of target organs to the hormonal treatment.

Abstract
The effects of the administration of gonadotropin-releasing hormone (GnRH) on the increase of testis and prostate volume was monitored by ultrasound in six patients affected by idiopathic hypogonadotropic hypogonadism. A significant increase of testis volume was observed after 90 and 180 days (6.65 versus 3.32 mL, 99.1% net increase and 8.47 mL, 176.8% increase, respectively) of pulsatile GnRH treatment. A similar increase of prostate volume was observed at day 90 (12.67 versus 7.78 mL, 70.3% net increase) and day 180 (14.70 mL, 97.7% increase). The ultrasound monitoring of the modifications of testis and prostate volume may represent a biological assay of the effects of GnRH treatment and offer additional data on the response of target organs to the hormonal treatment.
