151 out of 212 adolescents having had been treated by human chorionic gonadotrophin (HCG) before puberty because of undescended testes, were re-examined 7 to 12 years later at an individual age of at least 17 years. In 121 of them a semen specimen for sperm counts could be obtained. In 10 patients, however, no ejaculate could be collected because of their hypogonadism. 78 of these 121 patients examined by sperm count had a sufficient testicular descensus after HCG treatment. In 43 adolescents HCG therapy failed, therefore subsequent orchidopexy was performed. A normal sperm count was seen in only 39 per cent of the 121 patients. After unilateral testicular maldescensus 18%, after bilateral maldescensus 43% of the patients had to be evaluated as prospectively infertile. Maier and Spann reported sperm counts below 10(6)/ml in 9 out of 17 patients with bilateral maldescensus who had been treated by surgery alone. In the present study, however, only 9 out of 35 individuals treated for bilateral maldescensus by HCG alone showed sperm counts below 10(6)/ml. Plasma LH and FSH concentrations were determined in 93 patients, 6 out of which showed hypergonadotrophic values of FSH and sperm counts below 10(7)/ml. Subsequently, 3 cases of Klinefelter's syndrome could be diagnosed among the total group of 121 patients. The etiology of testicular maldescensus is by no means uniform since anatomical, endocrine and/or chromosomal factors are involved.
