The participation of extracellular vesicles in many cellular processes, including reproduction,
is unquestionable. Although currently, the tetraspanin proteins found in extracellular vesicles …

At coitus, human sperm are deposited into the anterior vagina, where, to avoid vaginal acid
and immune responses, they quickly contact cervical mucus and enter the cervix. Cervical …

The mammalian female reproductive tract interacts with sperm in various ways in order to
facilitate sperm migration to the egg while impeding migrations of pathogens into the tract, to …

Mammalian fertilization comprises sperm migration through the female reproductive tract,
biochemical and morphological changes to sperm, and sperm-egg interaction in the oviduct …

The oviduct plays a vital role in ensuring successful fertilization and normal early embryonic
development. The male inseminates many thousands or even millions of sperm, but this …

Mammalian spermatozoa are coated with a thick glycocalyx that is assembled during sperm
development, maturation, and upon contact with seminal fluid. The sperm glycocalyx is …

The present paper argues that while the Spanish for Heritage Learners (SHL) profession

In the pig, a functional tubal sperm reservoir (SR) is established before ovulation to ensure
availability of suitable numbers of viable spermatozoa for fertilization. The boar's large …

The fallopian tube is lined with a highly complex folded epithelium surrounding a lumen that
progressively narrows. To study the influence of this labyrinthine complexity on sperm …

The aim of this study was to evaluate the distribution of inhibin/activin alpha, beta (A) and
beta (B) subunits and follistatin in immature oocytes and in matured oocytes before and after …
