Methylation dynamics during folliculogenesis and early embryo development in sheep [PDF]

, 2017
Genome-wide DNA methylation reprogramming occurs during mammalian gametogenesis and early embryogenesis. Post-fertilization demethylation of paternal and maternal genomes is considered to occur by an active and passive mechanism respectively, in most ...

Antral follicle size in the downregulated cycle and its relation to in vitro fertilization outcome

Journal of Human Reproductive Sciences, 2009
Aim: In this study, we have attempted to relate the antral follicle size on day 3 of downregulation to the in vitro fertilization (IVF) outcome and hence test its predictive value for IVF outcome.

Irisin alleviated the reproductive endocrinal disorders of PCOS mice accompanied by changes in gut microbiota and metabolomic characteristics

Frontiers in Microbiology
IntroductionFolliculogenesis and oligo/anovulation are common pathophysiological characteristics in polycystic ovary syndrome (PCOS) patients, and it is also accompanied by gut microbiota dysbiosis.

Activation of GDF9 regulates human folliculogenesis

GDF9 is a key regulator of fertility in female mammals, as it controls the process of folliculogenesis. In this grant, we will demonstrate the importance of GDF9 in human folliculogenesis, determine the mechanisms that activate GDF9 and show why aberrant

Ovarian folliculogenesis in the oviparous Mexican lizard Ctenosaura pectinata

, 1996
The ovarian follicles of Ctenosaura pectinata exhibit a clear seasonal cycle in morphology. Early in development, each oocyte is surrounded by a granulosa composed of a single layer of cuboidal or squamous cells and thin thecal layers.
