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.

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.

When you hit retirement, so will literally everyone else. You want to hire a nurse to wipe your ass because you can't, there's a 25 year waiting list because everyone is old.
Your one grandchild has 6 older people to take care of in addition to their one child (spouse exactly in the same position)

Doesn't matter, you need working age people. A society can't function if it's all old people. Period

People would have lots of kids if each subsequent child didn’t make their existing family’s life much more difficult
iopq@lemmy.world · 1 pts · 1y
People used to have 5+ kids and it was considered fine. It's a cultural thing.
IhaveCrabs111@lemmy.world · 1 pts · 1y
The culture is linked to the income. People have more kids in poorer countries because they typically don’t have a social safety net so the only way to survive in old age is by having lots of children. When the countries become richer and get social security they start having less kids, especially when kids become a financial burden
iopq@lemmy.world · 2 pts · 1y
You're right, we need to dismantle the social safety net

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.

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

Yes, that sounds like a wonderful idea. Let’s put the reproductive future of the species under commercial and/or governmental control.
Both of those things are demonstrably trustworthy, especially in the last decade.
We should cede all control to them. Indeed.

Are you a young naive tech bro, or a Nazi Eugenicist? Is there a difference anymore? Have you even thought about what you are saying? That’s an insane take.
School_Lunch@lemmy.world · 15 pts · 1y
Um I never said anything about giving control to anyone... in fact I specifically said "voluntarily"... you seem like an angry person who is looking for things to be mad about. I'm not sure how you jumped to calling me a nazi.
I have thought about what I'm saying, have you? Unwanted pregnancies are something that by definition nobody wants. All I said was that this could be a way to address that, and you took that simple idea and ran to crazy town with it.

Because the population decline is mostly a western societal phenomenon induced by the late stage capitalism we are suffering from, and our planet dying from our carelessness. Other countries, especially poorer ones, are still happily making babies. So "population decline" effectively means the decline of western populations, and I can see how people (including me) might have an issue with that.
If all populations would shrink proportionally the same it would be a lot less contentious.

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.

I'm a bit dull to predict the future. But I can see we already have "ownership" of GMOs available for companies. The "Dire Wolves" that got resurrected that you don't hear about anymore belong to a company. We got plenty of examples of companies marketing something as positive, such as Monsanto saying they actually feed the planet and whatnot. Companies that start open source suddenly turning for profit. And unscrupulous governments and corruption.
And now you have unlocked the possibility of creating fully customized humans in a lab.
What could go wrong?
Don't get me wrong I totally see how the technology can also be used for good. That's what OpenAI says about their product, too.

Isnt this just cloning? Like if they grew sperm cells and eggs from my dandruff and combined them
RotSteinFinke@feddit.org · 7 pts · 1y
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.
Breadhax0r@lemmy.world · 1 pts · 1y
Would a sperm/egg combo from the same person not be a clone?
RotSteinFinke@feddit.org · 4 pts · 1y
The sperm and the egg would contain different copies of the chromosomes. The cell randomly divides its chromosomes when it becomes an egg or sperm. When they merge, two halves of a genome form a full one again. But some chromosomes would be there as doubles, others would be lost. The effect would be the same as incest. Mutations that would be hidden in a healthy cell would emerge.
Mothra@mander.xyz · 1 pts · 1y
I guess, if you manage to create both sperm and eggs from the same sample and then use it to create an embryo. It sounds prone to a lot of defects though, for the same reason it's not recommended to have offspring with your siblings. I don't think that's what they're going after here.
The presumption is that they would be able to combine sperm and eggs that are different enough to avoid this. Just like with any regular pregnancy.
Keep in mind we already know how to manipulate/edit genes to enhance or suppress traits. Being able to conceive an embryo in vitro means you can now create a human tailored to your liking, without even needing a womb. That's a couple steps beyond cloning.
