Anethole reduces oxidative stress and improves in vitro survival and activation of primordial follicles

Braz. j. med. biol. res; 51 (8), 2018
Primordial follicles, the main source of oocytes in the ovary, are essential for the maintenance of fertility throughout the reproductive lifespan. To the best of our knowledge, there are no reports describing the effect of anethole on this important ovarian follicle population. The aim of the study was ...

Missing and overexpressing proteins in domestic cat oocytes following vitrification and in vitro maturation as revealed by proteomic analysis

Biol. Res; 51 (), 2018
BACKGROUND: The domestic cat serves as an animal model for assisted reproductive studies of endangered felid species. To date, there are no data on the protein alterations following cryopreservation of oocytes in felid family. METHODS: Immature (germinal vesicle) domestic cat oocytes were vitrified in th...

Influence of epidermal growth factor (EGF) supplementation at different times of in vitro maturation of canine oocytes

The aim of this study was to evaluate the influence of epidermal growth factor (EGF) on in vitro maturation of canine oocytes at different times of the process. Ovaries were collected from 55 bitches considered healthy and aseptically isolated, immersed in physiological solution (0.9% NaCl) and transport...

Desempenho de doadoras leiteiras mestiças F1 (Gir x Holandês) no sistema de produção in vitro de embriões

O Brasil atualmente é detentor do terceiro maior rebanho de vacas leiteiras do mundo, composto, em sua maioria, de animais mestiços F1 (Gir X Holandês), os quais são bem adaptados às áreas tropicais. O objetivo do presente estudo foi investigar a eficiência da ovum pick-up (OPU) e da produção in...

Avaliação do fuso meiótico e distribuição cromossômica de oócitos maturados in vitro de portadoras da síndrome de ovários policístico submetidas à estimulação ovariana: estudo piloto
