FSH priming and hormonal modulation of oocyte competence in in vitro maturation for infertility treatment: a systematic review and meta-analysis

Frontiers in Endocrinology
BackgroundDoes follicle-stimulating hormone priming improve reproductive outcomes in women undergoing in vitro maturation treatment for infertility?Follicle-stimulating hormone (FSH) is a key endocrine regulator of oocyte folliculogenesis and is crucial ...

The beneficial effects of cumulus cells and oocyte-cumulus cell gap junctions depends on oocyte maturation and fertilization methods in mice

PeerJ, 2016
Cumulus cells are a group of closely associated granulosa cells that surround and nourish oocytes. Previous studies have shown that cumulus cells contribute to oocyte maturation and fertilization through gap junction communication.

Modulation by cAMP of a Slowly Activating Potassium Channel Expressed in \u3cem\u3eXenopus\u3c/em\u3e Oocytes [PDF]

, 1992
When expressed in the Xenopus oocyte, the minK protein induces a slowly activating voltage-dependent potassium current (Isk). We studied the modulation of this current by altering intracellular cAMP levels and found that the amplitude of Isk is ...

Equilibrium between anti‐oxidants and reactive oxygen species: a requisite for oocyte development and maturation

Reproductive Medicine and Biology, 2016
Reactive oxygen species (ROS) are required for cellular functioning and are controlled by anti‐oxidants. The ROS influence the follicles, oocytes, endometrium, and their environment.

Oocyte Maturation in Assisted Reproductive Techniques

Annals of the New York Academy of Sciences, 2006
Abstract:  Human oocyte maturation is a long process during which nuclear maturation occurs resulting in germinal vesicle breakdown (transition from prophase I to metaphase II) and extrusion of the first polar body. During oocyte maturation, in parallel with nuclear maturation, a number of events take place in the oocyte cytoplasm that assist ...
