The acrosome is a specialized organelle that covers the anterior part of the sperm nucleus and plays an essential role in the process of fertilization. The molecular mechanism underlying the ...

Spermiogenesis is a fundamental process required for the generation of the mature male gamete with a vesicle-like acrosome, a propelling flagellum, and condensed nucleus, which are all necessary for ...

Fertilization is the union of two cells: an egg and a sperm. Before the egg and the sperm fuse, an event known as the "acrosome reaction" needs to occur in the sperm. Now, a team from Osaka University ...

Nous sommes dans la même situation!!! Fin avril, nous avons commencé des examens (test post coïtal, spermogramme et spermocytogramme). Résultat ; bonne numération, mobilité trés moyenne mais le plus ...

Ferlins are a family of single transmembrane proteins with multiple calcium ion (Ca2+) binding C2 domains involved in Ca2+-mediated membrane fusion. Among other processes, ferlins participate in the ...

Sperm is a reproductive cell created in the testicles. Males produce millions of these cells each day, but it takes only one sperm to fertilize an egg. This article outlines what sperm are, where they ...
