[Fertility after orchiopexy for unilateral retention testis].
The testicular function after orchiopexy for unilateral cryptorchism was examined for fertile state with the relation to the age at operation and the testicular size. Sperm concentration decreased with the age at operation, accompanying a rise of gonadotropins and a decrease of the testicular size. The testicular size decreased with the age at operation. sperm deterioration was correlated more with the testicular size in the normally descending side than that of the operated one. The gonadotropin level was inversely correlated with the size of the contralateral normally descending testis. These results indicate that fertility after unilateral orchiopexy is influenced by the age at operation as well as the development of the normally descending contralateral testis.
