title: Disappearance of spermatoza from the ejaculates of vasectomized dogs.
abstract: Ejaculates of bilaterally vasectomized dogs contained spermatozoa as long as 21 days after vasectomy, indicating that spermatozoa in the canine ejaculate originated from both the epididymides and the vasa deferentia, not from the epididymides alone.
