The aim of this study was to investigate what components of porcine epididymal fluid (pEF) influences the nuclear maturation of porcine germinal vesicle oocytes. Porcine cumulus-oocytes complexes from follicles were cultured in TCM 199 containing pEF. After 48 h cultures, oocytes were examined for evidence of GV breakdown, metaphase I, anaphase-telophase I, and metaphase II. Maturation rate of oocytes was significantly increased in media supplemented with 10% pEF during in vitro maturation (IVM) than in those without pEF. When lipid component of pEF was removed by treating n-heptane, no significant difference was observed in maturation of oocytes between n-heptane treatrment and intact pEF group. However, the proportion of oocytes reaching at metaphase II (M II) was significantly (p<0.05) decreased in the oocytes cultured in media containing trypsin-treated pEF compared to those in media with intact pEF. When porcine GV oocytes were matured in the medium supplemented with intact pEF or pEF heated at 56'C and 97'C, rates of oocytes remained at GV stage were 11.7%, 29.4% and 42.0%, respectively. However, there were no difference in proportion of oocytes reaching at MII stage among intact pEF group and 56'C group. Present study suggests that 1) pEF contains an enhancing component(s) for nuclear maturation in vitro of oocytes, 2) protein(s) of pEF may be capable to promote nuclear maturation in vitro, and 3) enhancing component for nuclear maturation may consist of two factors, which are responsible for germinal vesicle breakdown (GVBD) and promotion of MII stage.
