[Results of treating cryptorchism with HCG in boys previously qualified for surgical treatment].

Hundred one boys, aged between 1.5 and 13 years, previously classified for surgery for uni- or bilateral cryptorchidism were examined. In 78 patients (77.2%) cryptorchidism was diagnosed, including 51 cases (50.5%) of unilateral undescended testicle. In the remaining 23 boys (22.9%) migrating testes were found: unilateral in 6 cases (5.9%) and bilateral in 17 cases (16.8%). An improvement was achieved after HCG therapy in 21 cases of migrating testes (91.3%), partial improvement in 1 case (4.35%), and no effect in 1 case (4.35%). The treatment with HCG produced recovery in 20 cases (25.6%) of cryptorchidism, partial improvement in cases (23.2%), and no effect in 40 cases (51.2%). A complete recovery was achieved in 41 out of 101 patients, i.e. in 40.6%, partial improvement in 19 cases (18.6%), and no effect in 41 cases (40.6%). The treatment with HCG enabled an avoidance of unnecessary surgery in 40.6% of all examined boys.
