Eugenol Improves Follicular Survival and Development During in vitro Culture of Goat Ovarian Tissue

open access: yesFrontiers in Veterinary Science, 2022
This study evaluated the effects of different concentrations (10, 20, or 40 μM) of eugenol (EUG 10, EUG 20, or EUG 40), ascorbic acid (50 μg/mL; AA) or anethole (300 μg/mL; ANE 300) on the in-vitro survival and development of goat preantral follicles and

Oocytes maintain ROS-free mitochondrial metabolism by suppressing complex I

open access: yesNature, 2022
Oocytes form before birth and remain viable for several decades before fertilization1. Although poor oocyte quality accounts for most female fertility problems, little is known about how oocytes maintain cellular fitness, or why their quality eventually ...

Current approaches for assisted oocyte maturation in camels

open access: yesJournal of Animal Reproduction and Biotechnology, 2021
Camel (camelus dromedarius) is a unique large mammalian species that can survive harsh environmental conditions and produce milk, meat, and wool. Camel reproduction is inferior when compared to other farm animal species such as cattle and sheep.

Altered germline cyst formation and oogenesis in Tex14 mutant mice

open access: yesBiology Open, 2021
During oocyte differentiation in mouse fetal ovaries, sister germ cells are connected by intercellular bridges, forming germline cysts. Within the cyst, primary oocytes form via gaining cytoplasm and organelles from sister germ cells through germ cell ...

Maturation of pig oocytes in vivo and in vitro.

open access: yesJournal of reproduction and fertility. Supplement, 2020
In this review the concept that the origins of embryonic failure occur during oocyte development is explored. The four factors that determine oocyte viability, namely a normal growth phase, adequate follicle cell support during maturation, the completion

Effect of harvesting technique and presence or absence of corpus luteum on in vitro development after parthenogenetic activation of oocytes recovered from buffalo ovaries [PDF]

open access: yesVeterinary World, 2014
Aim: The present study was aimed at assessing the influence of three oocyte harvesting (aspiration, puncture and slicing) methods and presence or absence of corpus luteum (CL) on recovery efficiency and subsequent in vitro maturation and parthenogenetic ...
