Dual effects of hydrogen sulfide donor on meiosis and cumulus expansion of porcine cumulus-oocyte complexes. [PDF]
PLoS ONE, 2014 Hydrogen sulfide (H2S) has been revealed to be a signal molecule with second messenger action in the somatic cells of many tissues, including the reproductive tract. The aim of this study was to address how exogenous H2S acts on the meiotic maturation of

Journal of Ovarian Research, 2023 Background The oocyte and its surrounding cumulus cells (CCs) exist as an inseparable entity. The maturation of the oocyte relies on communication between the oocyte and the surrounding CCs.

Aquaculture Reports, 2022 G Protein-coupled receptor 3 (Gpr3) plays a critical role in maintaining oocyte meiotic arrest in mammals. To ascertain the function of Gpr3 in oocyte maturation in fish, the Gpr3 cDNA was cloned from orange-spotted grouper (Epinephelus coioides).

Failure of oocyte maturation: Possible mechanisms for oocyte maturation arrest [PDF]
Human Reproduction, 2003 For human IVF, the patient's ovaries are hormonally stimulated to ensure the collection of fully matured oocytes that are at the metaphase II stage. Only these oocytes can be successfully fertilized either when mixed with sperm or after ICSI. Nevertheless, in some cases immature or maturing oocytes are recovered from follicles.

The role of oocyte maturation inhibitor in follicular regulation of oocyte maturation [PDF]
Reproduction, 1982 Meiotic maturation of mammalian oocytes is a protracted process, subject to multiple stop-go controls (Text-fig. 1). The meiotic process is initiated during fetal life and is arrested shortly after birth at the stage of diplotene. Normally meiosis is resumed in adult life following the preovulatory surge of gonadotrophins (Ayalon, Tsafriri, Lindner ...

Oocyte In Vitro Maturation with Crude Sperm Extract Protein of Bull's Spermatozoa
Journal of Experimental Life Science, 2016 Oocyte In vitro maturation (IVM) is one of the important parts for in vitro fertilization (IVF). The success of oocyte maturation is influenced by the composit ion and the quality of IVM medium.

Role of arachidonic acid cascade in Rhinella arenarum oocyte maturation [PDF]
, 2015 There are no studies that document the production of prostaglandins (PGs) or their role in Rhinella arenarum oocyte maturation. In this study, we analysed the effect of arachidonic acid (AA) andprostaglandins (PGs) on maturation, activation and ...

Involvement of PLA2, COX and LOX in Rhinella arenarum oocyte maturation [PDF]
, 2013 In Rhinella arenarum, progesterone is the physiological nuclear maturation inducer that interacts with oocyte surface and starts a cascade of events leading to germinal vesicle breakdown (GVBD).
