The oviductal sperm reservoir in domestic mammals
In all mammalian species studied to date, sperm cells are arrested in the caudal isthmus before ovulation to form an oviductal reservoir. When ovulation occurs, discrete numbers of sperm are released from this region and ascend to the ampulla where fertilization normally occurs. Experimental evidence indicates that the sperm reservoir is instrumental in delivering the appropriate number of sper...
متن کاملSperm fucosyltransferase-5 mediates spermatozoa-oviductal epithelial cell interaction to protect human spermatozoa from oxidative damage.
Oxidative damage by reactive oxygen species (ROS) is a major cause of sperm dysfunction. Excessive ROS generation reduces fertilization and enhances DNA damage of spermatozoa. Interaction between spermatozoa and oviductal epithelial cells improves the fertilizing ability of and reduces chromatin damage in spermatozoa. Our previous data showed that oviductal epithelial cell membrane proteins int...
متن کاملThe modulation of sperm function by the oviductal epithelium.
During their sojourn in the female tract, sperm come into contact with the epithelial cells that line the tract and their secretions. In the past, much attention has been given to the nature and composition of uterine and oviductal fluid [1-3] with the aim of understanding what components of these fluids may affect the events associated with fertilization and preimplantation embryo development....
متن کاملComparison of the Effect of Alpha Lipoic Acid (ALA) and Beta-Defensin 1 Protein on Human Sperm Motility and Viability in Different Times of Incubation
Background and Objectives: Antioxidant alpha lipoic acid and β-defensin 1 protein may have a positive effect on the quality of sperm parameters. In this study, the effect of sperm incubation with alpha lipoic acid antioxidant and β-defensin 1 protein were assessed on sperm motility and viability at different times. Methods: In this experimental study, routine semen analysis was carried out o...
متن کاملthe effect of taftan pozzolan on the compressive strength of concrete in the environmental conditions of oman sea (chabahar port)
cement is an essential ingredient in the concrete buildings. for production of cement considerable amount of fossil fuel and electrical energy is consumed. on the other hand for generating one tone of portland cement, nearly one ton of carbon dioxide is released. it shows that 7 percent of the total released carbon dioxide in the world relates to the cement industry. considering ecological issu...
