TLDR
Treatment of spermatozoa with PAF in severely asthenozoospermic males may be of therapeutic value, and the effects of synthetic PAF on the motility of human spermutozoa were evaluated.About:

Olfactory receptors are displayed on dog mature sperm cells.
TL;DR: It is demonstrated that a few dog genes representative of various subfamilies of olfactory receptors are expressed essentially in testis, with little or no expression in Olfactory mucosa, which is consistent with a role as sensor for unidentified chemicals possibly involved in the control of mammalian sperm maturation, migration, and/or fertilization.
Journal ArticleDOI
The implantation window.
TL;DR: The implantation window is defined as that period when the uterus is receptive for implantation of the free-lying blastocyst, which results from the programmed sequence of the action of oestrogen and progesterone on the endometrium.
Journal ArticleDOI
Effect of Cryoprotective Additives and Cryopreservation Protocol on Sperm Membrane Lipid Peroxidation and Recovery of Motile Human Sperm
TL;DR: The results support observations that there is a negative correlation between sperm motility and LPO in cryopreserved samples and discount the hypothesis that LPO protection is a result of the cryoprotective action of PAF or PTX.
Journal ArticleDOI
Stimulation of protein tyrosine phosphorylation by platelet-activating factor and progesterone in human spermatozoa
TL;DR: A role for tyrosine kinase(s) in the mechanism of capacitation and activation of human spermatozoa by PAF and progesterone is suggested.

Mechanisms of Fertilization in Mammals
TL;DR: This chapter will discuss how mammalian spermatozoa prepare themselves for fertilization and how the spermatozosa and eggs interact during fertilization.

TL;DR: The identification of cAMP-dependent protein kinase, calmodulin and myosin light chain kinase in the sperm head suggests that cAMP and calcium-dependent phosphorylations are also involved in the control of the fertilization process, i.e., the acrosome reaction, in a manner similar to that known for theControl of stimulus/secretion coupling.

Requirement of extracellular calcium ions for various stages of fertilization and fertilization-related phenomena in the hamster
TL;DR: Extracellular Ca2+ is apparently unnecessary for the attachment of spermatozoa to the zona and egg surfaces, decondensation of the sperm nucleus, and the development of sperm and egg pronuclei within the egg.

Partial characterization of the embryo-derived platelet-activating factor in mice.
TL;DR: The embryo-derived PAF displays chemical, biochemical and physiological properties similar to those of PAF-acether, as did 1-0-alkyl-2-acetyl-sn-glyceryl-3-phosphocholine (PAF-ACether).
