DISTRIBUTION OF SPERMATOZOA IN THE OVIDUCT AND FERTILITY IN DOMESTIC BIRDS

Abstract
Intramagnal insemination by a procedure which caused the deposition of large numbers of spermatozoa in infundibular glands but few or none in uterovaginal glands, resulted in prolonged fertility with an exceptionally high incidence of pre-oviposital embryonic mortality, as compared with the fertility resulting from insemination by techniques which deposited spermatozoa primarily in the uterovaginal glands.
