Following insemination of spermatozoa pre-ovulation, the mammalian oviduct ensures, by
the formation of a functional sperm reservoir (SR), that suitable (low) numbers of viable and …

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 …

Contents Fertilization and early embryo development relies on a complex interplay between
the Fallopian tube and the gametes before and after fertilization. Thereby the oviduct, as a …

In most mammals, the oocyte is surrounded with compact multilayers of cumulus cells; these
form cumulusoocyte complexes (COCs). During oocyte maturation, the COCs dramatically …

In mammals, the uterine mucosal immune system simultaneously recognizes and reacts to
most bacteria as well as allogenic sperm mainly through the Toll-like receptors (TLR) 2/4 …

Seminal plasma (SP) is a complex fluid containing proteins, peptides, enzymes, hormones
as well as extracellular vesicles (EVs). The SP interacts with spermatozoa and the inner cell …

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

The oviduct plays a role in successful animal reproduction not only in spermatozoa and ova
transport to the fertilization site but also by affording a microenvironment for fertilization and …

Hyaluronan (HA) is involved in several important steps of sperm storage and of fertilization.
This study investigates the presence and concentration of HA in oviductal fluid (ODF) …

In this prospective comparative study, compared with fertile control subjects (n= 12), infertile
patients with hydrosalpinx (n= 18) had lower E-cadherin and a trend toward decreased N …
