Scientists in Japan have created mice with two biologically male parents for the first time.
The team, led by a professor of genome biology at Osaka University in Japan, generated eggs from the skin cells of male mice.
When implanted into female mice, the eggs produced healthy pups, according to research published this month in the journal Nature.
The proof-of-concept research could expand the possibilities for future fertility treatments, including for same-sex couples.
However, scientists warn there is still much to learn before cultured cells can be used to produce human eggs in a lab dish.

One step closer
to that dystopian future where the patriarchy outright deems women "unnecessary." Like, don't get me wrong, not sayin' the research is bad to do... just that this is the entirely wrong time, culturally, for it to be *getting* done.

I saw this on Quora. Lots of
I saw this on Quora. Lots of women saying it will never happen and you still need a womb etc. There was talk of INCEL men etc. I thought I would poke the hornets nest and posted stuff about womb transplants and artificial wombs. i got a quite a reaction.
The same sort of reaction you get from men when women say they don't need them and tey can clone themselves. Apparently not.
Despite several highly publicized claims, human cloning still appears to be fiction. There currently is no solid scientific evidence that anyone has cloned human embryos.
In 1998, scientists in South Korea claimed to have successfully cloned a human embryo, but said the experiment was interrupted very early when the clone was just a group of four cells. In 2002, Clonaid, part of a religious group that believes humans were created by extraterrestrials, held a news conference to announce the birth of what it claimed to be the first cloned human, a girl named Eve. However, despite repeated requests by the research community and the news media, Clonaid never provided any evidence to confirm the existence of this clone or the other 12 human clones it purportedly created.
In 2004, a group led by Woo-Suk Hwang of Seoul National University in South Korea published a paper in the journal Science in which it claimed to have created a cloned human embryo in a test tube. However, an independent scientific committee later found no proof to support the claim and, in January 2006, Science announced that Hwang's paper had been retracted.
From a technical perspective, cloning humans and other primates is more difficult than in other mammals. One reason is that two proteins essential to cell division, known as spindle proteins, are located very close to the chromosomes in primate eggs. Consequently, removal of the egg's nucleus to make room for the donor nucleus also removes the spindle proteins, interfering with cell division. In other mammals, such as cats, rabbits and mice, the two spindle proteins are spread throughout the egg. So, removal of the egg's nucleus does not result in loss of spindle proteins. In addition, some dyes and the ultraviolet light used to remove the egg's nucleus can damage the primate cell and prevent it from growing.
