BACKGROUND In natural conception only a few sperm cells reach the ampulla or the site of
fertilization. This population is a selected group of cells since only motile cells can pass …

BACKGROUND The human sperm cell is very well suited for proteomic studies, as it is
accessible, can be easily purified and is believed to be transcriptionally and translationally …

BACKGROUND Knowledge of the proteomic composition of the gametes is essential to
understand reproductive functions. Most of the sperm proteins are related to …

Semen is a complex body fluid containing an admixture of spermatozoa suspended in
secretions from the testes and epididymis which are mixed at the time of ejaculation with …

Proteomic studies are contributing greatly to our understanding of the sperm cell, and more
detailed descriptions are expected to clarify additional cellular and molecular sperm …

Mammalian sperm motility is a prerequisite for in vivo fertilization, and alterations in this
parameter are commonly observed in infertile males. However, we still do not have a …

The male gamete (sperm) can fertilize an egg, and pass the male genetic information to the
offspring. It has long been thought that sperm had a simple protein composition. Efforts have …

Cryoinjury is a consequence of cryopreservation and may have a negative impact on sperm
quality regarding motility, morphology, and viability. This study was designed to identify …

Male germ cells undergo an extreme but fascinating process of chromatin remodeling that
begins in the testis during the last phase of spermatogenesis and continues through …

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