Sperm migration through the female genital tract is not a quiet journey. Uterine contractions
quickly operate a drastic selection, leading to a very restrictive number of sperm reaching …

Abstract 1 Hyaluronan (HA) is a non-sulfated gylcosaminglycan naturally occurring polymer
found in tissues and 2 fluids of mammals including the reproductive system. Its biosynthesis …

Millions or billions of sperm are deposited by artificial insemination or natural mating into the
cow reproductive tract but only a few arrive at the site of fertilization and only one fertilizes an …

The sperm reservoir is formed after insemination in mammals, allowing sperm storage in the
oviduct until their release. We previously showed that physiological concentrations of …

Therian (marsupial and eutherian) mammals have evolved a suite of novel reproductive
features–seen variously in their gametes, the steps of fertilization and the male reproductive …

Tannin (TA) improves porcine oocyte cytoplasmic maturation and subsequent embryonic
development after in vitro fertilization (IVF). However, the mechanism through which TA …

As the time of ovulation draws near, mouse spermatozoa move out of the isthmic reservoir,
which is a prerequisite for fertilization. However, the molecular mechanism remains unclear …

Background Molecules from the female reproductive tract modulate capacitation and
function of sperm cells in vivo. These molecules vary in a quantitative and qualitative …

Osteopontin (OPN) is a multifunctional phosphoprotein that has been linked to fertility in
bulls. However, the exact mechanism by which OPN contributes to fertilisation is yet …

Hyaluronan (hyaluronic acid) is a simple, nonantigenic, nonsulfated glycosaminoglycan
present everywhere in the extracellular compartments of the body. Noteworthy, it is highly …
