Diagram showing the reduction in number of the chromosomes in the process of maturation of the ovum; the process is known as meiosis Main article: Oogenesis The formation of an oocyte is called oocytogenesis, which is a part of oogenesis. [ 1 ]
Oogenesis starts with the process of developing primary oocytes, which occurs via the transformation of oogonia into primary oocytes, a process called oocytogenesis. [11] From one single oogonium, only one mature oocyte will rise, with 3 other cells called polar bodies.

Oocytogenesis : third trimester primary Oocyte: diploid/46: 4C: Ootidogenesis (meiosis 1) (Folliculogenesis) -- polar body separated: Dictyate in prophase I until ovulation secondary Oocyte: haploid/23: 2C: Ootidogenesis (meiosis 2) -- polar body separated: Halted in metaphase II until fertilization Ootid: haploid/23: 1C: Maturation: Minutes ...
An ovarian follicle is a roughly spheroid cellular aggregation set found in the ovaries.It secretes hormones that influence stages of the menstrual cycle.In humans, women have approximately 200,000 to 300,000 follicles at the time of puberty, [1] [2] each with the potential to release an egg cell (ovum) at ovulation for fertilization. [3]
The primary role of the follicle is oocyte support. From the whole pool of follicles a woman is born with, only 0.1% of them will rise ovulation, whereas 99.9% will break down (in a process called follicular atresia).
Background Chlorine and caustic soda are produced at chlor-alkali plants using mercury cells or the increasingly popular membrane technology that is mercury free and more energy-
The cumulus oophorus (discus proligerus) is a cluster of cells that surround the oocyte both in the ovarian follicle and after ovulation.In the antral follicle, it may be regarded as an extension of the membrana granulosa.
