Animals, 2023 Oocytes matured in vitro are useful for assisted human and farm animal reproduction. However, the quality of in vitro matured oocytes is usually lower than that of in vivo matured oocytes, possibly due to the absence of some important signal regulators ...

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.

A physiological approach for supporting oocyte-cumulus cell communication and chromatin remodelling at meiotic resumption [PDF]
, 2016 In vitro embryo production (IVP) remains inefficient in both clinical applications of human reproduction and animal breeding and the development of pre-maturation strategies to improve IVP is a mayor challenge in assisted reproductive technologies.

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.

, 2014 Oocyte maturation is a complex process involving nuclear and cytoplasmic maturation. The nuclear maturation is a chromosomal segregation and the cytoplasmic maturation involves the reorganization of the cytoplasmic organelles, mRNA transcription and ...

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).
