Hens with either regular uterine fluid secretion or irregular uterine fluid secretion were artificially inseminated through the transfer of sperm into the uterus. Twenty-four hours after  artificial insemination, 3 hens with regular  uterine fluid  secretion and 3 hens with irregular uterine fluid secretion were killed and the  utero-vaginal junction and infundibular sperm storage tubules were observed for the presence of sperm. There was no difference (P>0.05) in the fill rate of either the utero-vaginal junction sperm storage tubules or the infundibular sperm storage tubules between hens with regular or irregular uterine fluid  secretion. However, the sperm transferred into hens with regular uterine fluid  secretion had a longer lifespan and fertilization ability than the counterpart group (Psecretion from the hen uterus may sustain the longevity and fertilization ability of fowl sperm in the oviduct.}, keywords = {Fertilization ability,Sperm survival,Uterine fluid}, url = {https://psj.gau.ac.ir/article_1467.html}, eprint = {https://psj.gau.ac.ir/article_1467_6b37af324934ae2d72c557a5ec722ac9.pdf} }
