Untitled[edit]

New research (Nature, around March? 2004) doubts if all ova are already present at birth. In case of a mouse, Helloo :D:D. It is unclear if the same is possible for human beings. Also it is unclear of these ova can become embryo's. -- July 2005

Is it just me, or is the latin origin of the word ovum explained twice in the first paragraph? --IronChris 03:35, 31 March 2006 (UTC)

Yes, it is. Someone should do something about that. --Romarin 04:37, 31 March 2006 (UTC)
Done. --Romarin 04:46, 31 March 2006 (UTC)

Ova (120 micron) are not the largest cells in humans, the anterior horn cell (135 micron) is. —Preceding unsigned comment added by Lobstercake1 (talkcontribs) 00:58, 27 April 2009 (UTC)

Added more specific details about how ova form (i.e. meiosis). Please help! 68.173.113.106 (talk) 23:53, 11 January 2012 (UTC)

Simpler[edit]

Would it not be smarter to make the introduction simpler?--Filll 10:36, 10 December 2006 (UTC)


An ovum (plural ova) is a haploid female reproductive cell or gamete.

  • haploid? awkward definition of gamete.

The word is derived from Latin, meaning egg or egg cell.

  • could be worded better

Both animals and embryophytes have ova.

  • embryophyte?

The term ovule is used for the young ovum of an animal.

  • not quite sure what this means.

In some plants, such as algae, it is also called oosphere.

  • what about trees? This sentence is awkward.

These are my comments for whatever they are worth,--Filll 18:14, 13 December 2006 (UTC)


And, uhh... A womaqn is born with exactly how many ovums? Mike(Talk)/(Cont) 00:08, 19 April 2007 (UTC)

EXCUSE ME! This is interesting and all but do they have YOLKS?!!!!!!! —Preceding unsigned comment added by 24.186.176.94 (talk) 03:25, 21 February 2008 (UTC)

I would be very grateful if somebody could write a "Structure" section...--Bkkenny (talk) 17:49, 7 February 2009 (UTC)

augo from gk (anglisized as avgo) alpha, ipsilon, gamma, omicron means egg and predate ovum from latin? — Preceding unsigned comment added by 101.163.81.226 (talk) 01:59, 23 February 2013 (UTC)

Merge to Egg (biology)[edit]

I'm a little troubled that this article exists side by side with Egg. Any thoughts on merging this article into that one? arkuat (talk) 06:06, 3 June 2008 (UTC)

Or perhaps, as an editor suggests on Talk:Egg (biology), that article ought to be renamed Egg (bird) or Shelled egg or something like that, and more general material in that article that is not specific to that topic removed to this article. arkuat (talk) 06:23, 3 June 2008 (UTC)

I now think (based on the categories that Ovum has been assigned to) that part of this page ought to be split to a new article Human egg or Human ovum. Unfortunately, WP:Split doesn't make it clear how to suggest this with a tag. arkuat (talk) 06:50, 9 June 2008 (UTC)

science:[edit]

how do u do this homework —Preceding unsigned comment added by 92.10.101.7 (talk) 09:25, 28 September 2008 (UTC)


I was under the impression that it is called an secondary oocyte until the moment of fertilization with a sperm cell, and then it becomes an ovum??

Luring out the egg cell[edit]

There are proteins which sort-of home-in sperm cells to the ovum, right? Is it possible to make a protein which propagates trough mucus inside vagina, reaches the ovum and propagates it out of body? (just an idea...)

Is calling the ovum an "egg" a misnomer?[edit]

It's a cell, not a true egg, right? 64.184.253.134 (talk) 04:57, 9 September 2010 (UTC)

Human ovum mass[edit]

What is the mass of the average human ovum? We've got size but not weight in this article. The mass is quoted (without reference) as 2×10−9 kg over at Orders of magnitude (mass). tschwenn (talk) 14:57, 14 October 2010 (UTC)

Ovum vs. Secondary oocyte[edit]

In humans, fertilization occurs before a haploid female gamete is formed. It's not entirely clear in this article whether ovum refers to a diploid female cell that is fertilized or a haploid cell produced after fertilization. Is there a definitive consensus for which it refers to? Do other animals have the same timing for these events? Also, the text I'm using (Larsen's Human Embryology, 4th ed.) refers to the haploid cell as a "definitive oocyte". I think there someone should clarify the distinction between these terms: (secondary, definitive) oocyte, ootid, ovum, zygote. —Preceding unsigned comment added by 131.104.40.18 (talk) 20:47, 22 March 2011 (UTC)

What about chromosomes in ova[edit]

In the article that describes the spermatozoon, it says about X & Y chromosomes. Why it doesn't say anything here? Don't ova have chromosomes, too? Այնշախոր (talk) 07:39, 1 July 2011 (UTC)

I'm not involved with editing this page any. I just saw your question and read the article. My only guess is that since the ova only has the X chromosome ( and, therefore, doesn't determine the gender of the offspring, the X or Y chromosome of the spermatozoon does), the other editors didn't feel it necessary to note this. But I would agree that having something indicating this or wikilinking to another page regarding it would indeed improve the article. JoannaSerah (talk) 04:55, 1 September 2011 (UTC)

Ovum vs. egg cell[edit]

I'd prefer to call this page "Egg cell" in order to cover all female gametes of any organism group in one article. Now the disambiguation page for "Egg cell" redirects those in search of information on plant egg cells to "Gametophyte", which is misleading. In my opinion, this article should start with a general description of the function and characteristics of all egg cells, irrespective of organism group. Additional information for specific organism groups could then be given in separate sections labeled by the organism group name. Cricetus (talk) 11:53, 11 June 2013 (UTC)

rated top as high school/SAT biology content - tameeria 14:55, 17 February 2007 (UTC) This article is very animal-centric. It needs a section on egg cells in plants and algae, e.g. ova production in oogonia and female gametophytes. - tameeria 19:29, 18 February 2007 (UTC)
