The generation of live offspring from vitrified oocytes [PDF]

open access: yes, 2011
Oocyte cryopreservation is extremely beneficial for assisted reproductive technologies, the treatment of infertility and biotechnology and offers a viable alternative to embryo freezing and ovarian grafting approaches for the generation of embryonic stem

Regulation of the aryl hydrocarbon receptor activity in bovine cumulus-oocyte complexes during in vitro maturation: The role of EGFR and post-EGFR ERK1/2 signaling cascade [PDF]

open access: yes, 2020
The aryl hydrocarbon receptor (AhR) has been extensively characterized as an environmental sensor with major roles in xenobiotic-induced toxicity. Evidence is accumulating that these functions serve as adaptive mechanisms overlapping its physiological ...

Role of Mitochondria Transfer in Infertility: A Commentary

open access: yesCells, 2022
Mitochondria transfer techniques were first designed to prevent the transmission of diseases due to mutations in mtDNA, as these organelles are exclusively transmitted to the offspring by the oocyte.

Supplementation with small-extracellular vesicles from ovarian follicular fluid during in vitro production modulates bovine embryo development. [PDF]

open access: yesPLoS ONE, 2017
Pregnancy success results from the interaction of multiple factors, among them are folliculogenesis and early embryonic development. Failure during these different processes can lead to difficulties in conception.

Current Relevant Knowledge on Dog Reproductive Physiology – a Review

open access: yesScientific Papers Animal Science and Biotechnologies, 2023
Successful in vitro techniques depend on the possibility to mimic in vivo conditions. For this reason, knowledge on reproductive physiology is necessary to define an efficient entirely in vitro system to produce embryos.

Effect of In Vitro Maturation Technique and Alpha Lipoic Acid Supplementation on Oocyte Maturation Rate: Focus on Oxidative Status of Oocytes.

open access: yesInternational journal of fertility & sterility, 2016
Therapeutic potential of in vitro maturation (IVM) in infertility is growing with great promise. Although significant progress is obtained in recent years, existing IVM protocols are far from favorable results. The first aim of this study was to investigate whether two step IVM manner change reactive oxygen species (ROS) and total anti- oxidant ...

Effect of collection techniques on cumulus oocyte complexes (COCs) recovery, in vitro maturation and fertilization of goat oocytes [PDF]

open access: yes, 2013
The experiment was undertaken to study the effect of collection techniques on cumulus oocyte complexes (COCs) recovery, in vitro maturation (IVM) and in vitro fertilization (IVF) of goat oocytes. COCs were collected by three techniques viz.

The Effect of Cryopreservation Temperature and Time on Viability and In Vitro Maturation of Sheep Oocytes [PDF]

open access: yesJournal of Animal and Poultry Production, 2021
This study aim to compare the effects of freezing techniques on viability and in vitro maturation of sheep oocytes. This experiment was carried out in Animal Production Research Institute. Sheep ovaries were obtained from slaughterhouse.

Apoptosis and glucocorticoid-related genes mRNA expression is modulated by coenzyme Q10 supplementation during in vitro maturation and vitrification of bovine oocytes and cumulus cells.

open access: yesTheriogenology, 2022
Oocyte in vitro maturation (IVM) and vitrification procedures lead to detrimental effects on the overall oocyte quality. The addition of antioxidants during IVM, such as the coenzyme Q10 (Q10), has been demonstrated to positively impact on the cumulus ...
