title: Storage and evacuation of spermatozoa from the uterovaginal sperm-host glands in domestic fowl.
abstract: Autoradiography with 3H-labeled spermatozoa was utilized to study spermatozoal oviductal interrelationships. Results demonstrated that sperm displacement from the uterovaginal sperm-host glands did not occur in domestic fowl. Furthermore, there was no indication that phagocytosis of labeled spermatozoa by sperm gland epithelium occurred. Associated studies demonstrated that extensive head-to-head agglutination occurred between freshly ejaculated spermatozoa, but the ability to agglutinate was lost as the sperm cells aged. On the basis of these observations, it was proposed that agglutination may be the basic mechanism controlling sperm storage and release from the uterovaginal sperm-host glands. A working model to this effect was presented.
