Possible participation of oviducal movement in spermatozoal transport in domestic fowl.
Carbon particles suspended in saline were injected into the vagina, the uterus, or into the magnum, 5 to 10 or 50 to 55 min after an oviposition. Carbon particles injected into the uterus 5 to 10 min postoviposition reached the infundibulum within 5 to 10 min, and particles introduced 50 to 55 min after an oviposition were not transported to the anterior oviduct. When particles were injected intramagnally 50 to 55 min following an oviposition, they moved distally toward the uterus. Particles introduced into the uterus 5 to 10 min after an oxytocin-induced oviposition were transported to the anterior oviduct. Carbon particles deposited into the vagina remained in situ irrespective of the time deposited. These results suggest that a special oviducal movement, which is though to be caused by oviposition, participates in spermatozoal transport through the hen's oviduct.
