Quest to create viable human sex cells in lab progressing rapidly, with huge implications for reproduction

Scientists are just a few years from creating viable human sex cells in the lab, according to an internationally renowned pioneer of the field, who says the advance could open up biology-defying possibilities for reproduction.

Speaking to the Guardian, Prof Katsuhiko Hayashi, a developmental geneticist at the University of Osaka, said rapid progress is being made towards being able to transform adult skin or blood cells into eggs and sperm, a feat of genetic conjury known as in-vitro gametogenesis (IVG).

His own lab is about seven years away from the milestone, he predicts. Other frontrunners include a team at the University of Kyoto and a California-based startup, Conception Biosciences, whose Silicon Valley backers include the OpenAI founder, Sam Altman and whose CEO told the Guardian that growing eggs in the lab “might be the best tool we have to reverse population decline” and could pave the way for human gene editing.

I'll never understand people who complain about population decline. It's a good thing. There are too many people here already. My thought on reading the headline was that it could be used in a different way. Everyone could be voluntarily sterilized, and then when they are ready and willing to have a kid they could use this new method to produce sex cells. No more unwanted pregnancies.

Who is going to take care of all the old people? AI?

[–] School_Lunch@lemmy.world 1 points 5 days ago (1 children)

Who's gonna take care of everyone when earth reaches it's carrying capacity? Which is actually decreasing as we continue to ravage the planet.

Oh yeah who cares? It'll just be all the poor who suffer and die.

[–] iopq@lemmy.world 1 points 4 days ago

The Earth won't reach carrying capacity. Population is projected to max at 9 billion and after that it's going down

[–] Mediocre_Bard@lemmy.world 107 points 1 week ago (7 children)

Population decline is not a problem for humanity. It is a problem for capitalism.

Even worse they're probably looking at the projection and seeing a loss of revenue directly related to population rates. They want more sheep to feed their money making systems.

Depopulation is a problem for any economic system. You can't run any form of government or economy when young workers aren't contributing to the tax base and the aging population requires more and more care.

Sure as clockwork someone will come along and say tax the rich. That only works for so long in this scenario. The rich get rich off our backs. No backs, no rich.

That's the actual setup of ergo proxy...not that they are volountarily sterilised. The whole point us the artifucial womb. I don't know if you watched it but if you haven't, do it.

Ah yes great I feel at ease now, knowing Sam Altman gives the thumbs up to this

That little voice telling me this is a very sharp double edged sword probably doesn't know shit

[–] SGGeorwell@lemmy.world 7 points 1 week ago

There are so many double-edged swords lying around these days I feel like it’ll be death by a thousand cuts from double-edged swords.

I read five lines into the news and thought "oh well shoot, now billionaires are going to try reverse the population decline due to the shitty world they created so that they can continue to generate labour and revenue and make the rest of us fight for resources in an over crowded world". And what do you know Sam Altman was the first shit face to confirm my speculations.

Production of humans without ties to historical family lines, would they have a number for a surname?

Welcome to the brave new world order

And, in effect, eighty-three almost noseless black brachycephalic Deltas were cold-pressing. The fifty-six four-spindle chucking and turning machines were being manipulated by fifty-six aquiline and ginger Gammas. One hundred and seven heat-conditioned Epsilon Senegalese were working in the foundry. Thirty-three Delta females, long-headed, sandy, with narrow pelvises, and all within 20 millimetres of 1 metre 69 centimetres tall, were cutting screws. In the assembling room, the dynamos were being put together by two sets of Gamma-Plus dwarfs. The two low work-tables faced one another; between them crawled the conveyor with its load of separate parts; forty-seven blonde heads were confronted by forty-seven brown ones. Forty-seven snubs by forty-seven hooks; forty-seven receding by forty-seven prognathous chins. The completed mechanisms were inspected by eighteen identical curly auburn girls in Gamma green, packed in crates by thirty-four short-legged, left-handed male Delta-Minuses, and loaded into waiting trucks and lorries by sixty-three blue-eyed, flaxen and freckled Epsilon Semi-Morons.

Funnily enough I think I read that novel like twenty years ago

[–] masterofn001@lemmy.ca 6 points 1 week ago (1 children)

I still say it is/was much more prescient than 1984.

Aha. So that's why they don't care if everyone but the billionaires die.

Isnt this just cloning? Like if they grew sperm cells and eggs from my dandruff and combined them

[–] RotSteinFinke@feddit.org 6 points 1 week ago* (last edited 1 week ago) (2 children)

No, it is something different. Cloning creates a another being with the exact same DNA. This would allow people, who can't produce viable sperm/egg cells, to reproduce with their partner. First patients would be infertile men and women.

They are going after Hitler wet dream to create super human.

Military applications for ward of the state and "universal soldier" applications! Yay humanity.

[–] lemmie689@lemmy.sdf.org 4 points 1 week ago

You are a true believer. Blessings of the state, blessings of the masses. Thou art a subject of the divine. Created in the image of man, by the masses, for the masses. Let us be thankful we have an occupation to fill. Work hard; increase production, prevent accidents, and be happy.
