BACKGROUND The high rates of unintended pregnancy and the ever-growing world
population impose health, economic, social, and environmental threats to countries …

In mammals, motility and fertilizing ability of spermatozoa develop during their passage
through the epididymis. After ejaculation, sperm undergo capacitation and hyperactivation in …

In spite of inconclusive or negative outcomes from clinical studies, oral antioxidants are still
largely prescribed to infertile men to improve sperm motility and/or reduce sperm DNA …

Hu sheep (HS), a breed of sheep carrying the FecB mutation gene, is known for its “year-
round estrus and multiple births” and is an ideal model for studying the high fecundity …

Objective To design protein phosphatase 1 (PP1)–disrupting peptides covalently coupled to
inert cell-penetrating peptides (CPPs) as sychnologically organized bioportide constructs as …

A synthetic pyrethroid pesticide, bifenthrin, has been commonly used as an effective
exterminator, although the rise in its usage has raised concerns regarding its effects on the …

The quality of sperm significantly influences the reproductive efficiency of pig herds. High-

The review describes mechanisms of regulating the spermatozoa motor activity. The authors
present the enzymes involved in phosphorylation of axonemal proteins, action of various …

In mammals, testicular sperm exiting the seminiferous tubules are immotile. Mammalian
sperm gain motility and the ability to fertilize eggs during their passage through the …
