Well balanced and timed metabolism is essential for oocyte development. The effects of
extrinsic nutrients on oocyte maturation have been widely reported. In contrast, intrinsic …

Background: Cryopreservation of ovarian tissues and pre-antral follicles is a promising
prospect for preservation of women fertility. Objective: The aim of this study was to evaluate …

Background: Ketosis is one of the most frequent and costly metabolic disorders in high-
producing dairy cows, and negatively associated with the health and reproductive …

Gap junctional coupling between cumulus cells is required for oocytes to reach
developmental competence. Multiple connexins, which form these gap junctions, have been …

Cellular metabolism is a complex network of biochemical reactions fueling development with
energy and biomass; however, it can also shape the cellular epigenome. Indeed, some …

Background Effective fetal growth requires adequate maternal nutrition coupled to active
transport of nutrients across the placenta, which, in turn requires ATP. Epidemiological and …

Ovulation is a unique physiological phenomenon that is essential for sexual reproduction. It
refers to the entire process of ovarian follicle responses to hormonal stimulation resulting in …

Mitochondrial therapeutics such as NAD+-boosting used during the oocyte's growth phase
markedly improve oocyte quality in mice. Evaluating them in humans should focus on …

Mammalian follicles are constituted of a complex structure composed of several layers of
granulosa cells surrounding the oocyte and of theca cells that reside beneath its basement …

The vitrification of preantral follicles followed by in vitro growth (IVG) could be valuable to
produce fertilizable oocytes. However, the meiotic resumption rates of oocytes cultured from …
