Dose-dependent effects of frutalin on in vitro maturation and fertilization of pig oocytes
2018
Abstract The aim of the present study was to evaluate the effect of frutalin (FTL) on in vitro maturation (IVM), and fertilization (IVF) of pig oocytes. In the Experiment 1, cumulus-oocyte complexes (COCs) were submitted to IVM in maturation medium alone or supplemented with different FTL concentration (0.6, 6 and 60 μg/mL), or 0.3 μg/mL doxorubicin (DXR). After IVM, some oocytes were evaluated for chromatin configuration, and the remaining oocytes were submitted to in vitro fertilization. In Experiment 2, matured oocytes were fertilized in IVF medium alone (control) or in presence of different FTL concentration (0.6, 6 and 60 μg/mL), or 0.3 μg/mL DXR. After 18 h post fertilization, the endpoints penetration rate, monospermy, spermatozoa per oocyte, and the IVF efficiency were evaluated in both experiments. In Experiment 1, 6 and 60 μg/mL FTL, as well as DXR increased ( P P P P P P P P
