Evaluation of the role of human chorionic gonadotropin therapy in the management of retractile testes in children

Abstract

Background and objective: Retractile testis is relatively common in pediatric population. This study followed up boys with retractile testis to investigate the natural course and the need for hormonal therapy and surgical treatments.Methods: A total of 110 boys aged 1.5-10.1 years (mean: 3.2 years) diagnosed as retractile testes, 67 (60.9%) unilateral and 43 (39.09%) bilateral. The mean follow-up period was 4.9±1.3 years. The diagnosis is confirmed on history and examination and ultrasound was made for measuring the size of the testis.Results: A total of 47 (42.72%) cases received human chorionic gonadotropin (17 bilateral and 30 unilateral). Response occurred in 32 boys (68.1%),12 bilateral and 20 unilateral. Failure of response occurred in 15 boys (31.9%). Fourteen of 110 boys (12.72 %) were referred for orchiopexy, including 1 of 12 (8.3%) of bilateral cases and 2 of 20 (10%) of unilateral cases who responded to human chorionic gonadotropin injection, 2 of 5 bilateral cases (40%) and 1 in 10 unilateral cases (10%) in those did not respond to treatment. In those who did not receive treatment, orchiopexy was performed in 6 of 26 bilateral cases (23.1) and in 2 of 37 unilateral cases (5.4%). Conclusion: Although testicular descent was achieved by short-term hormone therapy, the study revealed that there is no significant statistical difference for the need for orchiopexy between those received and those did not receive human chorionic gonadotropin.
