Dynamics 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 کاملThe Correlation of the Follicular Fluid Levels of Anti-Mullerian Hormone and Beta Human Chorionic Gonadotropin with Oocyte Matura-tion
Background: Follicular fluid (FF) plays a key role in preparing a microenvironment for the development and fertilization of oocytes. Moreover, biochemical and hormonal changes in the FF surrounding the oocyte can affect its quality and successful fertilization. The present study was conducted to investigate the relationship of beta human chorionic gonadotropin (beta-HCG) and anti-mullerian horm...
متن کاملFollicular fluid markers of oocyte developmental potential.
BACKGROUND Concentrations of certain substances in follicular fluid (FF) are related to fertilization outcome and early post-fertilization development. The study aim was to identify FF markers with which to predict embryo implantation potential. METHODS Concentrations of selected hormones, cytokines and growth factors in individual FF samples obtained during assisted reproduction treatment we...
متن کاملEffect of Different Charged Groups of Cow Follicular Fluid Proteins on In Vitro Oocyte Maturation
Follicular fluid (FF) provides a very important microenvironment for the development of oocyte maturation, ovulation and fertilization. The objective of this study was to determine the effect of different charged groups of cow follicular fluid proteins on in vitro oocyte maturation (IVM) when added to cultured maturation medium. The follicular fluid were obtained from dominant follicle and prec...
متن کاملControl of oocyte growth and maturation by follicular cells and molecules present in follicular fluid. A review.
The aim of this review is to summarize the interactions between the oocyte and its surrounding granulosa cells which are involved in the control of oocyte growth or apoptosis as well as those playing a key role in the ability of the oocyte to undergo nuclear (resumption as meiosis to reach the MII stage) or cytoplasmic maturation (ability to fertilize and develop to the blastocyst stage). The r...
