Talk:Human fertilization

message: "
After the sperm enters the cytoplasm of the oocyte (also called ovocyte), the tail and the outer coating of the sperm disintegrate and the cortical reaction takes place, preventing other sperm from fertilizing the same egg. The oocyte now undergoes its second meiotic division producing the haploid ovum and releasing a polar body. The sperm nucleus then fuses with the ovum, enabling fusion of their genetic material.

If someone can find either a human or at least a mammalian research reference I would be most grateful. Thank you

message: This may be the wrong place for this, but how is the time between ejaculation and fertilization termed?

I don't think there is a term, since just because the male ejaculates doesn't always mean fertilization will occur. I have heard that spermatozoon can survive for up to 72 hrs in the uterus and fallopian tubes so if it doesn't find an egg by then, then there won't be a pregnancy. that's the only reference i've heard to that timespan, but i could be wrong.

This needs to be covered, though.  I came looking up "impregnation", expecting an article on that which would detail the journey of sperm to egg.  There isn't any such article, nor can I find that information anywhere on Wikipedia.  That's a serious major defect!  —Preceding unsigned comment added by 206.212.229.106 (talk) 07:41, 8 January 2010 (UTC)

message: I think that the egg pulls in the sperm, rather than the sperm pushing in/penetrating the egg. 
I also think that the egg can choose which sperm to let in, but I have no reference for this.

The article has to be technical to a certain degree to be factual.  After reading it over, I don't think it is more technical than it needs/has to be.  It also appears pretty well defined, therefor not in need of an expert to add to or correct it. JeremyWJ (talk) 09:01, 26 June 2009 (UTC)

thread_title:  External links modified 

message: From my reading of this article, everything in this article is relevant to the topic. This article carried some solid points and information that is of great importance which have expanded my knowledge of this specific topic. There was one thing that was not so much of a distraction in the article, but more of an eye opener, the fact that there is actually some disease in fertilization, which occurs when an egg is being fertilized by several sperm forming a fraternal twin. This, i did not know about and therefore I found it very interesting.Traceychung (talk) 02:15, 22 January 2018 (UTC)
thread_title:  Article Evaluation 

message: Overall the article gives a thorough overview of human fertilization. It states how fertilization begins from a female egg and male sperm. However, it does not go into detail about the four stages of development. I felt that it lacked information about the zygotic stage, the blastocyst stage, the embryonic stage, and the fetal stage. Moreover, the "cell membranes" section has only one sentence about fertilization and I believe it deserves more than one sentence. It would be appropriate to have information on how fertilization changes the cell membrane. Overall, the article explains the "fusion" section, and "fertilization age" section appropriately.

thread_title:  Article Evaluation  

message: The article has potential issues of vandalization and unsourced (dubious/false) content, one example being the (just removed) unreferenced false claim that eigth sperm can successfully fertilize a single human zygote. As this sentence was kept in the article for about ten years despite a reference missing template, and even got praised by one of the article "evaluators" I can only reccommend that the article is put under scrutiny and an expert revises the whole content.

thread_title:  Science 

message: Hi! I have been editing this article and have done some reorganization to describe events chronologically. I'm having some issues with the subsection "Cone of attraction and perivitelline membrane" because I am unclear on when this fits in the timeline of fertilization and am unable to find reputable sources that discuss it. I also find the wording a bit unclear. Maybe someone could edit this section to add more clarity and ensure that it is in the right place chronologically (or delete it if the facts cannot be corroborated).

thread_title:  Cone of attraction and perivitelline membrane section 

message: In 1991 Emily Martin wrote “The Egg and the Sperm,” arguing that the language used to describe fertilization relies on gender stereotypes. The egg is described to be passive while the sperm is active. One example of this is motion: the egg is said to move passively through the fallopian tube, while the sperm takes a “journey” or propels itself with a strong tail. Additionally, the sperm is often described as binding to the egg, which frames it as the active penetrator in accordance with gender roles. In reality, the ZP3 protein on the surface of the egg is the ligand and the sperm carries the receptor, making the egg’s protein the penetrator.
More recent studies have confirmed Emily Martin’s findings. A 2015 study on Youtube videos about conception found common themes among videos that showed how gender roles influence the portrayal of fertilization. The themes included that the videos were from the point of view of the sperm, the egg was shown to be waiting passively, the vagina was described to be dangerous, and the sperm’s behavior was described as warlike and violent. Another study from 2014 examined science textbooks ranging from middle school to medical school and similarly found that the egg was described to be passive while the sperm took an active journey, fertilization was described from the perspective of the sperm, and similes were commonly used that implied that the sperm was tough and masculine.
