在排卵前从人工授精供者的卵巢中取出卵子，让其在体外排卵，并将其转移到处女宿主的输卵管中，都未能产生可受精的卵子。从未交配的捐赠者卵巢中取出的11个卵子中，有9个被移植到人工授精的宿主的输卵管中，结果证明是可育的。胚胎死亡率很高，但这主要是由于移植过程中获得的感染。将新鲜精液直接注射到输卵管内，或直接注射到紧邻卵巢和输卵管的体腔内，通常会产生可受精的卵子。这些实验的结果表明，虽然不排除偶尔有鸡蛋在卵巢中受精的可能性，但家禽的卵子在从卵巢释放后通常是受精的。a.p.g。
OVA removed from the ovaries of artificially inseminated donors prior to ovulation, allowed to ovulatein vitro, and transferred to the oviducts of virgin hosts all failed to produce fertile eggs.Nine out of 11 eggs from ova taken from the ovaries of non-mated donors and transferred to the oviducts of artificially inseminated hosts proved to be fertile. Embryonic mortality was high, but this was largely due to infection acquired during the process of transfer.Fresh semen injected directly into the infundibulum, or into the body cavity immediately adjacent to the ovary and the infundibulum, generally led to the production of fertile eggs.The results of these experiments indicate that the ovum of the domestic fowl is normally fertilized after its release from the ovary, although the possibility that an occasional egg may be fertilized in the ovary is not excluded.
