Sperm transport in the female reproductive tract.
At coitus, human sperm are deposited into the anterior vagina, where, to avoid vaginal acid and immune responses, they quickly contact cervical mucus and enter the cervix. Cervical mucus filters out sperm with poor morphology and motility and as such only a minority of ejaculated sperm actually enter the cervix. In the uterus, muscular contractions may enhance passage of sperm through the uteri...
متن کاملSperm Storage in the Female Reproductive Tract in Birds
The ability to store sperm in the female genital tract is frequently observed in vertebrates as well as in invertebrates. Because of the presence of a system that maintains the ejaculated sperm alive in the female reproductive tract in a variety of animals, this strategy appears to be advantageous for animal reproduction. Although the occurrence and physiological reasons for sperm storage have ...
متن کاملSperm Transport in the Mare Reproductive Tract: A Review
The objective of this study was to review the literature on sperm transport in the mare. During this process the sperm cells must reach the oviducts in order to fertilize the oocyte, but before reaching this site it must go through the uterus that is a hostile environment at this moment since there is an inflammatory reaction in this location that aims to eliminate excess spermatozoa and bacter...
متن کاملDo sperm possess a molecular passport? Mechanistic insights into sperm selection in the female reproductive tract.
Most male mammals produce far more spermatozoa on a daily basis than is strictly necessary for reproduction and females have evolved mechanisms that prevent all but a small minority from reaching the vicinity of their oocytes. One potential explanation for the stringent selection is that females have developed these mechanisms as a way of avoiding polyspermy as well as exercising post-copulator...
متن کاملEffect of the Female Reproductive Tract on Sperm Metabolism in the Rabbit and Fowl
A fourfold increase in oxygen uptake by rabbit spermatozoa incubated in the rabbit uterus and a twofold increase in cock sperm¬ atozoa incubated in the hen's oviduct over ejaculated spermatozoa is the first reproducible biochemical change to be demonstrated in sperma¬ tozoa residing in the female genital tract. It was shown that these rapidly respiring spermatozoa were capacitated because they ...
