This study was designed 1) to determine the effectiveness of 2 in vitro maturation systems
commonly employed to produce nuclear and cytoplasmicly mature pig oocytes, 2) to assess …

Few embryos derived from pig oocytes matured and inseminated in vitro are able to develop
to blastocysts in culture. The present study was conducted to examine the effects of oocyte …

Three experiments were designed for the in vitro fertilization of in vivo matured oocytes
following different sperm treatments: In experiment I, spermatozoa (sperm rich fraction) were …

The present study was carried out to examine the effect of maturation media on male
pronucleus formation of pig oocyte matured and fertilized in vitro. Follicular oocytes collected …

The progression of meiosis in porcine oocytes maturedin vitro was examined and the effect
of maturation interval on the incidence of polyspermic fertilization and embryonic …

Polyspermic fertilization and embryo quality are important issues for the in vitro production of
pig embryos. We hypothesized that oocyte donor (prepubertal gilt vs. sow) affects …

The present study examined the effect of low culture temperature during in vitro maturation
(IVM) of pig oocytes on their nuclear maturation, fertilisation and subsequent embryo …

Porcine cumulus-oocyte complexes were cultured in BSA-free Whitten's medium or modified
Medium 199, each supplemented with porcine follicular fluid (PFF) and hormonal …

The developmental abilities of porcine oocytes matured and fertilized in vitro were examined
in vivo and in vitro. Cumulus-oocyte complexes were cultured in mM199 supplemented with …

The temporal progression of meiotic and cytoplasmic maturation of pig oocytes cultured in a
medium supplemented with 0.4% polyvinylalcohol (PVA), 10% fetal calf serum (FCS), 10 …
