Testicular spermatozoa acquire fertility only after 1 or 2 weeks of transit through the
epididymis. At the end of this several meters long epididymal tubule, the male gamete is …

Mammalian sperm must undergo a series of biochemical and physiological modifications,
collectively called capacitation, in the female reproductive tract prior to the acrosome …

Male fertility is the ability of sperm to fertilize the egg and sustain embryo development.
Several factors determine the fertilizing capacity of mammalian sperm, including those …

Calcium is an essential ion which regulates sperm motility, capacitation and the acrosome
reaction (AR), three processes necessary for successful fertilization. The AR enables the …

Metabolites play essential roles in biological systems, but detailed identities and
significance of the seminal plasma metabolome related to bull fertility are still unknown. The …

Background Subfertility decreases the efficiency of the cattle industry because artificial
insemination employs spermatozoa from a single bull to inseminate thousands of cows …

Global demand for animal proteins is increasing, necessitating increased efficiency of global
food production. Improving reproductive efficiency of beef cattle, especially bull fertility, is …

Background Mammalian spermatozoa must undergo capacitation, before becoming
competent for fertilization. Despite its importance, the fundamental molecular mechanisms of …

Fertility is one of the most economically important traits in both beef and dairy cattle
production; however, only female fertility is typically subjected to selection. Male and female …

In mammals, transit through the epididymis, which involves the acquisition, loss and
modification of proteins, is required to confer motility and fertilization competency to sperm …
