From this article:

A primary oocyte is just a kind of initial oocyte that is formed by mitosis of an oogonium into two primary oocytes. Each primary oocyte forms by meiosis two secondary oocytes, and each secondary oocyte divides into one ootid.

Each ootid, in turn, differentiates into an ovum

From Oogenesis:

In mammals, oogonial transformation into oocytes (oocytogenesis) is completed either before or shortly after birth. The further development comes to a rest during prophase I of meiosis until puberty. In Ascaris, the oocyte does not even begin meiosis until the sperm touches it.

In meiosis, the oocyte divides in four, of which only one becomes an ovum, the others becoming polar bodies. There may be two polar bodies, in which case one is diploid and did not undergo meiosis II.

This article would seem to have it that each secondary oocyte simply becomes an ootid, whereas the other seems to include more in the process. Should this be put in? Also, should the ootid stage go in the other article? I'm not entirely confident about these changes, so I will leave them to someone with more background.

Pronunciation of "oocyte"

How do you pronounce "oocyte"? An IPA transcription might be useful. 128.12.20.195 21:45, 18 January 2006 (UTC)[reply]

"Oocyte" is pronounced ōˈə-sīt (oh-ə-site) [1]

confusing article

This page is quite confusing and possibly inaccurate. I only know human biology and it may be different in other mammals, although I suspect not.

Oogonia are the promordial germ cells that proliferate in the fetal ovary. They then enter the first meiosis division but do not complete it. Oocytes arrested at this stage are termed primary oocytes. Only those which are ovulated complete the first meiosis division, giving rise to a secondary oocyte, which receives the vast majority of the cells constituents, and a polar body. The polar body may degenerate.

Secodary oocytes arrest in the second meiosis division and do not complete it unless fertilised. A second polar body is formed at this point, again far smaller than the sister cell formed by the meiosis division. The first polar body may also enter meiosis II.

An oocyte is simply a female germ cell that has begun the process of meiosis.

Hello Evilhypnotist. I think it is confusing, too. Could you fix the article using proper sources. Either website or a science textbook, or both. My To Do list is very long, and I have more pressing matter to attend to today. If you put the information on the page, I can help format it if you need help. (Not sure whether you are an experienced user or not) Thanks, FloNight ^talk 15:36, 19 February 2006 (UTC)[reply]

Definately some mistakes as pointed out. ex: I believe meiosis I is being called mitosis early in the article.

Re-write?

I agree that there are mistakes and confusion on this page. There is also some material of doubtful relevance, for example the bit about the rainbow trout on a page which is otherwise purely about human biology. I will be happy to tackle these when I have time, which means in July. Overall the page needs what would in effect be a re-write, though there is some good material which I would retain. I feel competent to do this, though I am not an expert. Can I suggest that I do it in July if no-one better qualified has time to do it first?

I am a new user, and I have never before made a substantial edit. So please feel free to correct me if I am going about this in the wrong way. Prim Ethics (talk) 19:48, 18 May 2008 (UTC)[reply]

egg

I added the parenthetical word "egg" after "immature ovum". I'm not a biologist; feel free to edit for elegance/clarity/technical precision. But please leave the word egg somewhere prominent in the lede, to provide context for the Latin-challenged. Thanks, Trovatore (talk) 21:16, 18 May 2008 (UTC)[reply]

Egg, egg cell and ovum are ambiguos words to me. I think a primary or secondary ovocyte is an inmature egg or inmature egg cell, an ovule or ovum is a mature egg ou mature egg cell (it completed the meiosis). A zygote is a fertilized egg with fused pronuclei. Am I wrong? I think it is better to use the more precise terms primary ovocyte, secondary ovocyte, ovule or ovum, and zygote.--Miguelferig (talk) 20:50, 17 June 2013 (UTC)[reply]

Improving interrelated coherence

I have added internal reference in the role of the paternal cell. The description of the role of the sperm during fertilization seems to me more accurate in the related article. I hope it helps in the goal of making this article clearer. Poissonbreaker (talk) 12:36, 24 June 2012 (UTC)[reply]

"Nest" single sentence ending seems wrong

"The space within an ovum or immature ovum is located is the cell-nest Cup uh mukiyam bigil uh." - just doesn't seem right somehow. Can somebody fix this? 01:44, 20 May 2021 (UTC)

No, it doesn't somehow :-) Un-vandalized. Thanks for noticing. Saintrain (talk) 22:37, 22 May 2021 (UTC)[reply]
