简要总结
In vitro maturation (IVM) is a technique for obtaining potentially fertilizable oocytes from immature oocytes. An oocyte must be mature both nuclearly and cytoplasmically in order to be competent in the reproductive process. Nuclear maturation involves an oocyte in metaphase II stage and is easily evaluated for its morphology. However, cytoplasmic maturation can only be evaluated by in vitro fertilization of that oocyte A mature nuclear and cytoplasmic oocyte is one capable of producing a viable embryo. This study aims to fine-tune the in vitro maturation (IVM) technique to achieve nuclear mature oocytes, i.e., to mature the oocytes up to the metaphase II stage. In addition, an artificial oocyte activation (AOA) will be carried out to check the cytoplasmic maturation of the oocytes, avoiding the generation of potentially viable embryos.
The aim of this study is to evaluate the response to the strategy stimulation with highly purified human menopausal gonadotropin (hMG-HP) administered for three days, in association with a standard methodology of in vitro oocyte maturation (IVM), to be performed on oocyte donors.
The correct functioning of this IVM technique would mean a reduction in the costs of ovarian stimulation treatments, as lower doses and shorter stimulation times are required, which implies lower risks for women derived from the medication and less stress for them.
