Female fertility relies on successful egg development. Besides chromosome segregation,
complex structural and biochemical changes in the cytoplasmic compartment are necessary …

BACKGROUND In a growth phase occurring during most of folliculogenesis, the oocyte
produces and accumulates molecules and organelles that are fundamental for the …

Assisted reproduction technology (ART) has become an attractive option for infertility
treatment and holds tremendous promise. However, at present, there is still room for …

BACKGROUND: With improved prospects for the use of human oocyte in-vitro maturation in
assisted reproductive technologies, the need to define more clearly the coordination of …

The ultrastructural analysis of oocytes and ovarian follicles has been used to evaluate the
effects of assisted reproductive techniques, such as cryopreservation or in vitro oocyte …

BACKGROUND: This work addresses the hypothesis that events occurring within the follicle
soon after the LH surge are essential for coordinating morphogenesis of the spindle and …

The aim of this study was to examine the effect of different stimulation protocols on oocyte
granularity and to determine the influence of cytoplasmic granularity on further embryo …

Oocyte maturation is pertinent to the success of in vitro maturation (IVM), which is used to
overcome female infertility, and produced over 5000 live births worldwide. However, the …

OBJECTIVE: To observe the ultrastructure of human oocytes at different maturity stages and
morphologies before and after in vitro maturation. DESIGN: Case report. SETTING …

STUDY HYPOTHESIS How does the ultrastructure of human oocytes matured in vitro
compare with oocytes collected from women after full hormonal stimulation? STUDY …
