Background: The difference of undescended testis initial position has significant effect on expected surgical results. The authors evaluate effect of HCG injection on testicular position in palpable undescended testis. Methods: Sixty patients with 77 palpable undescended testes were clinically examined and underwent ultrasonographic examination followed by intramuscular HCG injection according to WHO recommended dosage system; 250 IU in age <1year, 500 lU in age 1-5years, 1000 lU in age >5 years, twice a week for 5 weeks for all age groups. Another clinical and ultrasonographic examination was done 1 week and 2 months after last injection of HCG. Results: From total 77 testes of patients injected with HCG; 14 testes failed to improve in position (18.2%), 62 testes showed 1 degree of improvement (from inguinal to prescrotal or from prescrotal to scrotal location) (80.5%) and 1 testis showed 2 degrees of improvement (from inguinal to scrotal location) (1.3%). 35 testes reached a scrotal position and did not need to undergo surgery (45.5 %). Conclusion: Intramuscular injection of HCG as neoadjuvant therapy in cryptorchid boys induced testicular descend to scrotum in 45.5% of cases and improved position of testis prior to orchidopexy in 36.3% of study group. Total 81.8% of the injected study group gained benefit from suggested therapy Key words: undescended testis - HCG - orchidopexy.
