In vitro fertilization (IVF) gives rise to embryos in a number of mammalian species and is
currently widely used for assisted reproduction in humans and for genetic purposes in cattle …

Most male mammals produce far more spermatozoa on a daily basis than is strictly
necessary for reproduction and females have evolved mechanisms that prevent all but a …

Ca2+-dependent mechanisms are critical for successful completion of fertilization. Here, we
demonstrate that CRISP1, a sperm protein involved in mammalian fertilization, is also …

Abstract Although 90%–100% of mouse oocytes can be fertilized in vitro with capacitated
spermatozoa within 1 h after insemination, oocytes within the oviduct are fertilized one by …

Butana and Kenana are two types of zebu cattle found in Sudan. They are unique amongst
African indigenous zebu cattle because of their high milk production. Aiming to understand …

To accomplish fertilization in the oviductal ampulla, ejaculated sperm are required to migrate
through the female reproductive tract. However, this fundamental process largely remains …

After insemination in the cow, a sperm reservoir is formed within the oviducts, allowing the
storage and then progressive release of spermatozoa toward the ovulated oocyte. In order to …

More than 1 million infertility treatments are practiced around the world per year, but only
30% of the couples succeed in taking a baby home. Reproductive technology depends in …

Mammalian sperm become fertilization‐competent in the oviduct, during a process known as
capacitation that involves the acquisition of the ability to exocytose the acrosome but also …
