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

Metformin promotes in vitro maturation of oocytes from aged mice by attenuating mitochondrial oxidative stress via SIRT3-dependent SOD2ac

open access: yesFrontiers in Cell and Developmental Biology, 2022
Human female fecundity decreases irreversibly as chronological age rises, adversely affecting oocyte quality, consequently worsening pregnancy outcomes and increasing the extent of birth defects.

Oocyte cryopreservation review: outcomes of medical oocyte cryopreservation and planned oocyte cryopreservation [PDF]

open access: yesReproductive Biology and Endocrinology, 2022
Abstract Background The utilization of oocyte cryopreservation (OC) has become popularized with increasing numbers of reproductive-aged patients desiring to maintain fertility for future family building. OC was initially used for fertility preservation in postmenarchal patients prior to gonadotoxic therapies; however, it

Dynamic Changes in Proteome during Yak Oocyte Maturation Analyzed Using iTRAQ Technology

open access: yesAnimals, 2023
The aim of this study was to investigate protein regulation at different time points during the in vitro maturation of yak oocytes. Yak oocytes at GV, MI, and MII stages were collected during in vitro maturation, and differential proteomics sequencing ...

Oocyte cryopreservation [PDF]

open access: yesHuman Reproduction, 1998
Cryopreservation of human oocytes has been employed with little success in clinical practice, even though it may solve the legal and ethical problems linked to embryo freezing. Various attempts to cryopreserve human oocytes have mostly been unsuccessful, leading to low oocyte survival rates after thawing, and the search for an optimal protocol for ...

Oocyte maturation [PDF]

open access: yesHuman Reproduction, 1998
Primary oocytes recovered from small and growing follicles of > or = 3 mm in the ovaries of untreated women, can be matured in vitro, will fertilize and develop in vitro, and when transferred to the patient, develop to term. However, the implantation rate of cleaved embryos has been disappointingly low and when embryos are allowed to develop beyond the

Equol: A Microbiota Metabolite Able to Alleviate the Negative Effects of Zearalenone during In Vitro Culture of Ovine Preantral Follicles

open access: yesToxins, 2019
The impact of zearalenone (ZEN) on female reproduction remains an issue, since its effects may differ among exposed cell types. Besides the use of decontaminants in animal diet, other approaches should be considered to minimise ZEN effects after exposure.
