Abstract: | 1. Unilateral cryptorchidism was associated with an increase in specific DAN activity in the abdominal testis of adult rats. 2. In the scrotal, immature testis, there was an age-dependent decrease in specific DAN activity similar to that normally seen in rats. This decrease was less pronounced in the abdominal testis of unilaterally cryptorchid rats. 3. Total DAN activity in the abdominal testis showed a decrease in both immature and adult rats, when compared to that of the scrotal testis. 4. Orchidopexy following cryptorchidism in adult rats, resulted in complete restoration of DAN activity in spite of poor recovery of spermatogenesis. |
