Human Oocyte - Germinal Vesicle

Morphology of the human oocyte at germinal vesicle (GV) stage. The germinal vesicle is the term used to describes the oocyte nucleus.


Germinal vesicle - (GV) Term used to describe an oocyte development stage occurring within the ovarian follicle that is before meiosis 1 and meiosis 2. The nuclear chromatin changes can also be divided into an early decondensed phase (nucleolus not surrounded by heterochromatin) and a later chromatin condensed phase (perinucleolar rings can occur depending on species).
