Embryological Aspects of Oocyte In Vitro Maturation
In Vitro Maturation (IVM) is a method that immature oocytes in antral follicles are extracted and matured in laboratry conditions. This review has attempted to provide the current knowledge and recent findings in in vitro maturation of oocytes and highlights the most important factors involved in this process. The review is based on literature reports and the author’s experience. In IVM cycles,...
متن کاملDynamics of human follicular growth and in-vitro oocyte maturation.
The physiological trigger for meiotic resumption in the human oocyte is the surge of luteinizing hormone, but it can also occur spontaneously if oocytes are released from antral follicles and cultured in vitro. The development of novel techniques for the culture of murine oocytes has raised the possibility of growing human oocytes to maturity in vitro. Such a system could open the door to a num...
متن کاملDynamic changes of the Golgi apparatus during bovine in vitro oocyte maturation.
For successful fertilization by the male gamete, oocyte cytoplasmic organelles such as the Golgi apparatus have to undergo specific changes: the entire process is known as cytoplasmic maturation. The goal of this study was to unravel the dynamics of the Golgi apparatus in bovine oocytes at critical stages of in vitro maturation, i.e. germinal vesicle (GV), GV breakdown (GVBD), metaphase I (MI) ...
متن کاملInsulin exposure during in vitro bovine oocyte maturation changes blastocyst gene expression and developmental potential.
Metabolic imbalance impairs fertility, because changes in concentrations of metabolites and hormones in the blood and follicular fluid create an unfavourable environment for early embryonic development. Insulin is a key metabolic hormone known for its effects on fertility: insulin concentrations are increased during energy balance disturbances in diabetes or metabolic syndrome. Still, insulin i...
متن کاملIn Vitro Oocyte Maturation in Polycystic Ovarian Syndrome Patients
Prevalence of Polycystic Ovarian Syndrome(PCOS) in Iran is more than 6%. Therefore we encounter with many PCOS patients. In Vitro Maturation (IVM) of oocytes as an attractive method in ART is considered. Studies show that changes in culture conditions should be administered to make IVM protocol more successful .For this purpose in this study we have set up the beneficial cultures for IVM proced...
