Are you gay or straight male, that may soon become a moot question.

What makes a man a man? Socially, that is a complicated question. Genetically, however, it is as simple as a single Y chromosome .

...that started before BOB the Blue Dolphin.

Seriously, do they know what happens when the gene pool gets down to three manufactured ones?

I don't see a problem here. Having children is hereditary. If your parents didn't have children, its unlikely you will have children.

That would follow within the reasoning, yes. lol

It happened to me a few years ago, I didn't know it was contagious though.

I can't see guys disappearing anytime soon. Mine has about 30 years to go. Our oldest's bf has about 60 to go. My nephew has about 75 to go.

in a few millenia, the article says. Gee, big worry there, considering the earth probably won't sustain human life that long due to sun expansion. Adios humanity either way.

Exactly! We can barely plan for 2 decades away, let alone a thousand. Waaaaay too many variables.

Two decades? It's tough enough getting politicians to plan 4 years ahead! And you're talking decades? Our politicians can't see that far.

The referenced article in the first post in this string defies critical thought. Sterility can't be inherited....

Please explain how a sterile man with a defective Y chromosome is able to pass that bad chromosome on to the next generation of males...

Yes they can father females, but no males and therefore that's the end of the line for that defective Y chromosome. So this article fails a logic test.

Politicians, yeah. Most can't see past their noses. But most people aren't pols.

Sterility? All it would take is for women to give birth to more girls than boys. Eventually boys would become a rarity.

Someone told me years ago that having kids is hereditary, if your parents didn't have any kids, chances are you won't either.................

The issue is that the human Y chromosome has few functional genes. It used to have the same number as the Y chromosome, but over time (millennia), its been shedding genes.

Every so often, a man is born with a mutation on their Y chromosome which causes them to not be able to produce fertile sons. But men with functional Y's can produce fertile sons. So the fertile Y proceeds to the next generation while the defective sterile Y comes to a dead end.

Eventually this process will reach the point where the Y chromosome has shed every unnecessary gene. But it can't go beyond that point while men are required for reproduction.

However its possible that in the future women with medical intervention could reproduce without men. In which case, men and the Y chromosome could become obsolete.

Last I heard was that sterility is the inability to produce whether what would be produced would have x chomosomes or the pair (or "z"s for all that matters. ) .

If man becomes obsolete then it stands to reason that the human species will end as we know it, and as you say "the future women (should then be person) could sexually reproduce without men. In which case, men and the Y chromosome would become obsolete."

British scientists at Newcastle wrote about creating synthetic sperm in the journal "Stem Cells and Development". It was reported in Science or SciAm. They said it''ll take a few years before they have it perfected.

Okay, it was American Scientist I guess. https://www.americanscientist.org/sc...le-infertility

Well hope it can cut the grass, fix a leaky toilet or shxits gonna fly.

Women don't have a Y chromosome. Women have an XX pair, while men have XY pair. A defective Y would only affect men.

Ordinarily. lol Although some "men" I have doubts about. Are you suggesting that I was wrong or something? Men with Y chromasomes that have shed a couple genes can reproduce, you know. It's just that they'll likely have girls as offspring.

Explain how you come up with this, because I can't see it.

No- I actually think someone told me they got it off some comedian on the Ed Sullivan show. It was when I first started working for the Gov't. about 1964.

"Y chromosomes with defective male-specific genes, especially those involved in sperm production, are unlikely to reproduce and pass on those genes to their sons, which knocks highly defective chromosomes out of the gene pool. Genetic changes that do not favor reproduction are likely to get weeded out of the system."

So I am wrong.

Men with defective Y's have problems fathering children of both sexes. Their daughters are normal, but their sons will inherit their father's fertility problems. Mutated badly enough and the man is sterile and they can't father children of either sex, due to low sperm production.

Well, me too, in a sense. I said they'd be more likely to have girls, which isn't necessarily true. The girls will more likely to be normal than the boys.
