Sperm motility control

PKA, germ cells, and fertility. The germ cells are supported structurally, nutritionally, and functionally by the Sertoli cells. Results indicate that sperm motility and sperm counts increased in the TS treated groups in a dose-dependent manner. Sperm oxidative stress and the effect of an oral Vitamin E and selenium supplement on semen quality in infertile men. Evidence from sertoli cell-depleted rats indicates that spermatid number in adults depends on numbers of sertoli cells produced during perinatal development. We have also isolated and purified a different kDa protein from caprine cauda epididymal plasma, which acts as a quiescence factor to immobilize cauda spermatozoa — the sperm motility quiescence factor QF. The reaction mixture was incubated in a boiling water bath for one hour.

Evidence-Based Complementary and Alternative Medicine

Addition of theophylline and bicarbonate does not activate further MSP-induced motility. We are IntechOpen, the world's leading publisher of Open Access books. Cytoskeleton 27 , — This is due to a lectin-like molecule located on the sperm surface that specifically interacts with its receptor of neighboring homologous cells. A 48 kDa integral membrane phosphoprotein orchestrates the cytoskeletal dynamics that generate amoeboid cell motility in Ascaris sperm. MIP loses activity by actions of alpha-mannosidase and beta-N-acetylglucosaminidase, thereby showing the sugar side chains responsible for the motility initiating potential.

Regulation of flagellar dynein by calcium and a role for an axonemal calmodulin and calmodulin-dependent kinase. It has been estimated that over proteins are involved in the specialized regulation of spermatogenesis [ 4 , 5 ]. Abstract Genetic defects during spermatogenesis can lead to a reduction in sperm motility and cause male infertility. Ion channels in sperm physiology.

In a cuvette containing 2. Asian Journal of Andrology , 12 1 , 47— The epididymal sperm count and motility of the mice treated with CP were significantly decreased compared to the control group. A simple protocol was followed to assess sperm susceptibility to oxidative stress on sperm motility. Role of volume-stimulated osmolyte and anion channels in volume regulation by mammalian sperm.
