Regulation of Sperm-Egg Fusion at the Plasma Membrane

Okabe M, Cummins JM Mechanisms of sperm-egg interactions emerging from gene-manipulated animals. A cross-over experimental design was used to segregate effects on early stages of capacitation, spanning the first 5 h of incubation, from those on acrosome reactions and zona penetration during the last 1 h. Annu Rev Cell Dev Biol — Notably, membrane fusion occurring intercellularly between a sperm and an egg is essential for fertilization. Zona penetration and hyperactivation were highly correlated. Considerable efforts are being devoted to understanding the molecular basis of cell-cell fusion; however, the exact mechanism s of the fusion process remain unclear.

Couzin J Cell biology: the ins and outs of exosomes. Zona penetration and hyperactivation were highly correlated. Abstract The bicarbonate: CO2 HCOCO2 concentration dependencies of hamster sperm motility, spontaneous acrosome reactions, and zona penetration used to assay the zona-induced acrosome reaction were examined.

Description: When HCOCO2 was continuously present, both progressive and hyperactivated motility were stimulated by HCOCO2 in a dose-dependent manner by h, well before completion of capacitation. We have no conflict of interest. Advertisement Hide. Menko AS, Boettiger D Occupation of the extracellular matrix receptor, integrin, is a control point for myogenic differentiation.

Oh! Most importantly, masturbation can be an EXTREME stress-reliever. So, by all means, if masturbation is nothing but a source of frustration, don't do it! But if you want to work with your body and try to gain these benefits, your body will thank you. :)
