Semen is known to contain an ovulation-inducing factor (identified as a nerve growth factor,
NGF) that shows a significant increase in ovulation after semen deposition in induced …

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 …

Oocyte development within avian ovarian follicles is an intricate process involving yolk
deposition and the formation of extraoocytic matrices. Of these, the perivitelline membrane …

Extracellular vesicles (EVs) carry bioactive cargoes involved in the early preimplantation
development. This study investigated the effects of EVs obtained from an oviductal epithelial …

The local immune system in the oviduct has a unique ability to deal with pathogens,
allogeneic spermatozoa, and the semi-allogeneic embryo. To achieve this, it seems likely …

Previously, our group demonstrated that recombinant porcine oviductin (pOVGP1) binds to
the zona pellucida (ZP) of in vitro-matured (IVM) porcine oocytes with a positive effect on in …

Cumulus cell (CC) expansion is pivotal for oocyte maturation, during which CCs release
factors that initiate paracrine signaling within the follicular fluid (FF). The FF is abundant in …

Background Exosomes are nanosized membranous vesicles secreted by various types of
cells, which facilitate intercellular communication by transporting bioactive compounds …

Successful implantation of porcine conceptus requires synergistic interaction with various
signal molecules in the maternal uterus. Extracellular vesicles (EVs) in uterine luminal fluid …

Sperm are allogenic to the female genital tract; however, oviducts provide optimal conditions
for survival and capacitation of these non-self cells until fertilization. Recently, we showed …
