Talk:Folliculogenesis

Untitled
The labels in the folliculogenesis diagram (Folliclesinovary.jpg) are incorrect - they have been reversed.  The arrow is pointing in the wrong direction "Corpus albicans" should be "Primary follicle" "Mature corpus luteum" should be "Secondary follicle" "Corpus luteum" should be "Graafian follicle" or "Mature vesicular follicle" etc.

I have already e-mailed the contact person at the National Cancer Institute (the source of this image as listed at http://en.wikipedia.org/wiki/Image:Folliclesinovary.jpg) Stefan

I agree, this needs to be changed. Plus the titles of the other two pictures "Histological presentation of...." are incorrect these are not histological pictures they are schematic diagrams.

Fair use rationale for Image:Mature Graffian follicle.jpg
Image:Mature Graffian follicle.jpg is being used on this article. I notice the image page specifies that the image is being used under fair use but there is no explanation or rationale as to why its use in this Wikipedia article constitutes fair use. In addition to the boilerplate fair use template, you must also write out on the image description page a specific explanation or rationale for why using this image in each article is consistent with fair use.

Please go to the image description page and edit it to include a fair use rationale. Using one of the templates at Fair use rationale guideline is an easy way to insure that your image is in compliance with Wikipedia policy, but remember that you must complete the template. Do not simply insert a blank template on an image page.

If there is other fair use media, consider checking that you have specified the fair use rationale on the other images used on this page. Note that any fair use images lacking such an explanation can be deleted one week after being tagged, as described on criteria for speedy deletion. If you have any questions please ask them at the Media copyright questions page. Thank you.

Length of Folliculogenesis
It says that folliculogenesis, from the time of a primordial follicle up to the point it becomes a dominant follicle, last for 375 days, equivalent to about 13 menstrual cycles. I'm not sure if this is verified, and most literature I've read tend to either describe the length of folliculogenesis as (i) only spanning from the conclusion of the last luteal phase (i.e. when FSH rises again with the decay of the corpus luteum several days prior to menses) and therefore being ~2 weeks long, or (ii) occuring over 3-4 menstrual cycles and therefore 3-4 months long. —Preceding unsigned comment added by 124.191.36.219 (talk) 16:13, 3 December 2009 (UTC)

Secondary/tertiary follicle
In the following sentences, is stated that both follicular stages are defined by appearance of the antrum.

"The acquisition of antrum marks the graduation of the primary follicle to the secondary follicle."

"The tertiary follicle, also known as a Graafian follicle or antral follicle, is marked by the formation of a fluid-filled cavity adjacent to the oocyte called the antrum."

Furthermore, according to < Junqueira's Basic Histology: Text & Atlas, 12e > the secondary follicle is also called an antral follicle, not the tertiary, as stated in the article.

" (...) the antrum (Figures 22–3 and 22–7a), producing follicles now called secondary or antral follicles." —Preceding unsigned comment added by 130.243.175.125 (talk) 16:51, 1 November 2010 (UTC)

Folliculogenesis in adult individuals
Since this paper it appears that it's not clear some statements about a closed number of folicles an its involvement in menopausia. Please, let's seek an expert to make it clear.--Gustavocarra (talk) 17:09, 10 March 2012 (UTC)

timeline for folliculogenesis
Please refer to Fig. 2 in Endocrine Reviews 21(2): 200–214. According to this paper, even if you assume that the primordial to primary follicle transition is one day long, the overall time from this transition to ovulation is greater than 7 menstrual cycles. — Preceding unsigned comment added by 142.158.254.202 (talk) 15:51, 30 October 2013 (UTC)

== Another way of showing question =

Look at image 3, this is declared a secondary follicle with an approximate diameter of 0.2mm. That is 1/1000 of the 2cm length in 4cm x 3cm x 2cm given as an adult ovary size here on the page on ovary. This is less than ten times larger than size of a primordial follicle at 0.03mm. For the simplification of math lets say that the primordial follicle was even smaller being .02mm. That would make it 1/10,000 of the lesser length in the size of an adult ovary. That gives you the dimensions of 2/10,000 x 1.5/10,000 x 1/10,000 of an ovary being the size of a primordial follicle. This yields the possibility of less than 30,000 total primordial follicles(being that they are actually .03 - .05mm in diameter) in an adult ovary if it contained solely primordial follicles. It does not however. Therefor, I conclude it to be mathematically impossible for an ovary to contain this primordial follicle cell count, and I postulate that they are actually formed inside the ovary just as with spermatogenesis. Do the math your self if you don't believe. Also try using V=(4/3)πr3 for volume and obtain a total volume of 1,000,000 primordial follicles (or 500,000 as per ovary) and then work backwards to gain a minimum required radius of such a volume r = 3√((V÷(4/3))÷π). You will find the same error in cell count of primordial follicles related to required radial size if the ovary's dimensions were adjusted to a sphere shape 3x3x3.
