The effect of follicular fluid hormones on oocyte recovery after ovarian stimulation: FSH level predicts oocyte recovery [PDF]

open access: yesReproductive Biology and Endocrinology, 2009
Background Ovarian stimulation for assisted reproductive technology (ART) overcomes the physiologic process to develop a single dominant follicle. However, following stimulation, egg recovery rates are not 100%.

DNA methylation mechanisms in the maturing and ageing oocyte [PDF]

open access: yesEpigenetics & Chromatin
Oocyte maturation involves both nuclear and cytoplasmic processes that are critical for the acquisition of oocyte competence. Granulosa cells, surrounding the oocyte, play a pivotal role in the maturation process, with mechanisms such as cAMP signaling ...

The Presence of Immature GV− Stage Oocytes during IVF/ICSI Is a Marker of Poor Oocyte Quality: A Pilot Study

open access: yesMedical Sciences, 2020
