Background Although millions or even billions of sperm are deposited in the female genital
tract, only very few sperm reach the oocyte, and only one single spermatozoon will …

Mammalian fertilization is comprised of many steps including sperm survival in the uterus,
sperm migration in the female reproductive tract, physiological and morphological changes …

The oviduct (known as the fallopian tube in humans) is the site for fertilization and pre-
implantation embryo development. Female steroid hormones, estrogen and progesterone …

Recalling the evolutionary sequence of development first of gonad and subsequently of
oviducts, ovarian endocrine regulation of all known components of oviduct physiology is …

Background The mammalian oviduct provides the optimal environment for gamete
maturation including sperm capacitation, fertilization, and development of the early embryo …

Previously, we identified a 215 kd glycoprotein, GP215, which is associated with
postovulatory oocytes and embryos, but not with preovulatory oocytes (Kapur and …

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 …

The notion of a gamete recognition system that alerts females to the presence of gametes in
their reproductive tract profoundly influences our understanding of the physiology of events …

Mammalian oviduct is the physiological site for sperm capacitation, gamete fertilization and
early embryonic development. The secretory cells lining the lumen of the mammalian …

In large mammals, millions of sperm are necessary to fertilize only a few oocytes (reviewed
in [1, 2]). Artificial insemination has been used to increase reproductive efficiency, but still …
