YY[edit]

Couldn't a male egg lead to a child with two Y chromosomes? Should this be addressed in the article? Junulo (talk) 20:40, 6 December 2007 (UTC)[reply]

It wouldn't be viable, couldn't get born. —Preceding unsigned comment added by 79.118.182.197 (talk) 16:05, 21 August 2010 (UTC)[reply]

It wouldn't even be able to become a zygote with YY chromosomes, we could create a large number of eggs from one man and a large number of sperm from another man. 25% will get the X chromosomes of both and become girls, 25% will get the Y chromosomes from both and not form viable embryos, and 50% will get the Y chromosome from one and the X chromosome from another and become boys. So 2/3 children of two men will become boys and 1/3 will become girls, and all the children of two women will become girls SiliconProphet (talk) 14:38, 23 July 2021 (UTC)[reply]

Self-fertilization[edit]

Would this make it possible for a man to procreate with himself? I could get an egg, fill it with my genes and then fertilize it using my own sperm - quite interesting, actually. Is it a clone? Or something more than a clone? —Preceding unsigned comment added by 84.202.66.193 (talk) 00:19, 28 December 2007 (UTC)[reply]

i don't think that baby would turn out well. it would probably be very inbred, because that is more like breeding. cloning is where the egg has no dna at all. —Preceding unsigned comment added by 69.182.75.51 (talk) 21:36, 17 January 2008 (UTC)[reply]

It would be very inbred as quite possibly nearly all genes will be homozygous SiliconProphet (talk) 14:38, 23 July 2021 (UTC)[reply]

Adoption[edit]

Why don't they just spare all the money and adopt a child in need? :( BirdValiant (talk) 08:40, 26 January 2008 (UTC)[reply]

Because many people myself included feel a cultural or biological or religious need to have biological children of their own SiliconProphet (talk) 14:38, 23 July 2021 (UTC)[reply]

DNA methylation[edit]

I am not an expert in reproductive science but I thought that the DNA contained within egg cells and sperm cells were methylated in different patterns so that the embryo would know how to express its father's genes and its mother's genes at differnet times/ways (like why your mother's genes determine if a man will go bald later in life). I believe they have already merged 2 eggs and concluded that the embryo died because the new genome did not contain the necessary paternal genes/gene taging. Does anyone know more? Further I believe that the Butantan Institue in Brazil is working on producing egg and sperm cells from male body cells. But I am not familiar with searching biological research material as I would like. If anyone could expand upon my question and statement I would most appreciate it. 134.243.210.14 (talk) 22:18, 29 December 2008 (UTC)[reply]

This study supports this notion ^[1] it was controlled for with bimaternal mice but not bipaternal mice MaitreyaVaruna (talk) 20:53, 9 April 2022 (UTC)[reply]

I have no knowledge of this. It seems pseudoscientific but might just be dated SiliconProphet (talk) 14:38, 23 July 2021 (UTC)[reply]

Bigotry...[edit]

This page is linked from Male pregnancy. I thought I'd bring some inconsistencies. That page mentions human males have given birth before. Obviously male eggs and female sperm exist, otherwise that couldn't happen! A Male could have sperm or eggs, and a female could sperm or eggs, it's a matter of chance what of the two "sexes" those people are born into, it's deeply offensive to the transgender community to say otherwise! It's equivalent to saying they not real womyn/men! I am guessing this article and a lot of the articles about human reproduction were written by cisheteronormative males. Unfortunately, the "free" encyclopedia doesn't appear to be free of the kyriarchical grip of "scientistic" (read privileged) white men. — Preceding unsigned comment added by 5.66.72.230 (talk) 01:15, 13 February 2015 (UTC)[reply]

While I appreciate this perspective and want to help be inclusive to LGBT people, at the same time we have to be quite clear about what we are talking about. I hope you have started editing articles so that you can bring a non-cisheteronormative non-white perspective to the free encyclopedia SiliconProphet (talk) 14:38, 23 July 2021 (UTC)[reply]
