Platelet activating factor sperm

Insulin-like growth factors and IGF-binding proteins in bovine seminal plasma. Removal of this enzyme during capacitation may promote PAF synthesis increasing motility and fertilization. The effects of platelet activating factor on mouse oocyte fertilization in vitro. Artery ; The concentration of PAF in human sperm was originally found to be inversely related to sperm quality [17]. This PAF binding results in increased sperm motility, acrosome reaction, fertilization and subsequent preimplantation embryo development rates. Trends Pharmacol Sci ; 8:

Purpose: To evaluate the effects of follicular fluid and platelet-activating factor on sperm motion characteristics of cryopreserved oligospermic and normospermic samples. PAF receptor modulators. Sixteen oligospermic samples and 20 normospermic samples were examined. J Assis: Reprod Genet. YanagimachiR, YanagimachiH, RogersBJ The use of zona-free animal ova as a test-system for the assessment of the fertilizing capacity of human sperm. Biochim Biophys Acta ;— It does this through binding to PAF receptors found in the sperm membrane.

J Exp Med ;— 3. Immunofluorescent evidence of the platelet-activating factor receptor on human spermatozoa. Effect of Artificial stimulants on cryopreserved spermatozoa from cancer patients. Studies found that PAF could not be modified without losing its biological activity.
