Sperm retention cysts in the efferent duct and testicular atrophy of TE inbred rats.
Sperm retention cysts were observed in the efferent duct of TE inbred rats at 15 weeks of age. Spermatozoa agglutinated in the efferent duct with destruction of the epithelium. Testicular weight increased or decreased. Diameter of the seminiferous tubules was enlarged in testes that increased in weight and germinal cells degenerated in the atrophied testes. After 30 weeks of age, the tubules of the efferent duct were sometimes replaced by scars and testicular atrophy became more frequent. In 3 out of 5 normal rats united by parabiosis with TE males for 25-27 days, cysts occurred in the efferent duct.
