All land plants alternate diploid/haploid
- I don't think this is true, many many land plants are polyploid Polyploid, should the wording be updated to clarify? Edman007 (talk) 02:05, 25 April 2016 (UTC)

How big is an ovum?
The article says an ovum is "visible to the naked eye." That's a good start as far as a qualitative answer to the question... but let's get a quantitative measurement into the article as well. 75.163.155.188 (talk) 02:50, 19 November 2016 (UTC)

Is this correct?
"The human ova grow from primitive germ cells that are embedded in the substance of the ovaries. Each of them divides repeatedly to give secretions of the uterine glands, ultimately forming a blastocyst.[3]"

A blastocyst is a fertilized egg, right? So this is not necessarily the end stage of a developing egg.

edit: In addition I have to say the article is quite disappointing and should be rewritten in an expanded form.

Diagram with the haploid nucleus in human oocyte has an error
Hello, the article has a diagram of the "human ovum cell", and it has an error. Mammals do not have the stage when meiosis has ended and fertilization has not occurred yet. Meiotic division does not end till fertilization in mammals, so there should be no haploid nucleus formed. Instead meiotic spindle should be shown close to the membrane, no nuclear membrane should be present. See e.g. this diagram from this article.

On the other hand, it could be a non mammal oocyte, but it needs specification. No, on second thought, it can't, because it has very specific for mammals cells surrounding it. So this diagram has an error that can be fixed only by redrawing it. Sorry, I do not know how to fix this error myself.

Additionally this image could be replaced by this one. It is distributed under creative commons license, but I don't know how to upload it here.

(2024-04-01): I removed the incorrect image. — Preceding unsigned comment added by 134.174.140.195 (talk) 16:28, 1 April 2024 (UTC)

Egg cell → Ovum – undiscussed merge; ovum by far the more usual name over 6 million hits to egg cell over 1 million; ngrams much higher register for Ovum; ovum used considerably on other pages. Iztwoz (talk) 12:44, 22 January 2019 (UTC)

erroneous information re ova formation in adult women
The sources do not support the statement given. Oocytes have formed from stem cells after implantation into rats, but no formation has been observed in adult women. Suggesting to delete that paragraph. 66.131.169.112 (talk) 05:38, 23 October 2022 (UTC)


 * I have replaced the paragraph with a more cautious and balanced account based on the ovarian stem cell article. Random person no 362478479 (talk) 19:07, 14 March 2023 (UTC)
