Keeping Chickens. I understand, and perhaps I misunderstand, that the sperm of the rooster is stored in the hens body until a egg passes by and then it is fertilized?

Given the volume of the GD relative to a single sperm, another possible function of polyspermy may be to activate specific molecular factors in the GD cytoplasm thereby initiating the process of embryogenesis. Little is known concerning the cellular and molecular mechanisms that sustain sperm within the SST lumen for prolonged periods of storage. Progesterone was the predominant steroid hormone found in seminal plasma see results below , which led us to test the effects of P4 on the ability of sperm to fertilize the egg. In addition, the chromatin of rooster sperm contains no cysteine residues [ 65 ] and lacks the potential stabilizing effect of S-S bonds of mammalian sperm chromatin. Alternatively, about days before their first ovulation, hens mate, sperm ascend the vagina and then enter the SSTs.

Gam, S. Fructose concentrations in seminal plasma from men with nonobstructive azoospermia. In birds, early preliminary studies showed contrasted effects of seminal plasma fractions on refrigerated rooster sperm [ 8 ], and a global deleterious effect in chickens and turkeys [ 9 , 10 ], but its effects on frozen semen have never been studied.
