The Effects of Cryptorchism in the Guinea Pig on the Isoenzymes of Testicular Lactate Dehydrogenase

Abstract

Unilateral cryptorchism was produced in guinea pigs by returning one testis to the abdominal cavity and by preventing its re-entry into the inguinal canal and scrotal sac. The retained testes were examined after 1-2, 3-4, or 5-7 weeks and estimates made of lactate dehydrogenase activity.
