Roles of the reproductive tract in modifications of the sperm membrane surface
Successful fertilization requires viable and functional spermatozoa to recognize and fuse with the oocyte. In most mammalian species, mature spermatozoa are not capable of fertilizing the oocytes immediately after ejaculation. However, unlike somatic cells, spermatozoa, after leaving the testis, are transcriptionally and translationally silent; therefore, upon completion of spermiogenesis, sper...
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 کاملSperm 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 کاملThe Extraction and Purification of Boar Sperm Surface Protein
Immunological sperm sexing is one of the desirable choices to separate X and Y sperm. The basic concept of immunological technique is based on the different proteins on the surface of X and Y sperms. To investigate the sperm surface proteins, proteomic investigation using 2 dimensional gel (2D-gel) electrophoresis technique has been applied. The initial step, protein extraction is very importan...
متن کاملP-17: Expression of Cell Surface Toll-Like Receptors in the Human Male Reproductive Tract
Background: Male infertility refers to the inability of a male to achieve a pregnancy in a fertile female. The root of many causes of infertility is miscommunication between immune and reproductive system. Male reproductive system is very sensitive and vulnerable, infections can hinder maturation and movement of spermatozoa lead to impaired fertility.All species need an immediate reply to the m...
