The effects of early experimental cryptorchidism and subsequent orchidopexy on the maturation of the guinea-pig testicle

Abstract

Abstract A histological study of experimental cryptorchidism in the immature guinea-pig and the results of subsequent orchidopexy are described. Arrest of development of a testis was produced by delaying its descent into the scrotum. Subsequent orchidopexy at ages up to and beyond puberty allowed development to continue to active spermatogenesis. The poor results following orchidopexy for natural cryptorchidism in man are discussed in relation to this experimental work and the existence of a primary testicular abnormality is suggested. The superficial inguinal pouch ectopic testicle and the retractile testicle are also discussed.
