New Research Shows You Can Grow Sperm In a Dish (sciencemag.org)
sciencehabit writes: How the male body produces sperm has long been hidden inside its genitalia. Trying to recreate the process in a lab for humans and other mammals has led to many failures - sperm development appeared to be dependent on unique conditions in the testes. But a new technique may finally be bringing that process into the open. A team of Chinese researchers reports turning a dish of a certain type of mouse stem cell into spermlike cells, which were then used to fertilize eggs and produce healthy mouse pups. The approach could help researchers study mammalian sperm development more directly, and it could spur efforts to develop treatments for male infertility in people.
Seems that we've solved that problem.
I produce plenty, don't need a dish, only a web connection.
Table-ized A.I.
perhaps one of the male lab assistants had a sense of humour and was left alone in the lab for a while.
>> it could spur efforts to develop treatments for male infertility in people. ...because the one thing this planet needs is even more humans?
A few years of unsuccessfully trying to have a baby would change your opinion and attitude on the subject.
Well guys, it took millions of years but we're finally redundant.
This is probably a great thing for lesbian couples trying to conceive. No more going to sperm bank and picking out some random stranger to be the father of your kids. Now just make sperm from your partners stem cells.
Oh, so you're where all those old mouse balls went...
for the rape kit. a little gene mod here/a little there...profit!
I, for one, welcome the new tidal wave of science fiction, social justice flamewars, and legislation that follows this. This is so promising, I may buy popcorn futures.
Mz. Sheldon, your future has arrived.
There is a nasty strand within feminism that regards all men as inherently evil. The prospect of being able to finally declare us redundant is therefore quite attractive to such people.This story is about one who had an abortion just because it was a boy http://www.inquisitr.com/18276...
You can grow ANYTHING in a dish!
And fixing the washing machine. That's about it guys. Other than that we are no longer needed by women.
Us guys need to get Boston Dynamics to develop the ultimate sex-bot, and then men and women can forevermore go their separate ways....
If telephones are outlawed, then only outlaws will have telephones.
Don't make me Godwin you, because, so help me, I'll do it!
So adopt. Plenty of kids out there who could use a good home. I have several friends who've done cross-racial adoption too... there's no reason your kids need to look like you.
Not to mention having bad genes- ie can't make sperm. Might be interesting idea though for Vets that have had their genitalia blown off.
love is just extroverted narcissism
Birth rates in advanced countries are already well below the rate of replacement. In some countries, it's so low they're going to see significant population declines. The only place birth rates are still up are in the most underdeveloped parts of the world, and even in moderately developed countries it's tapered off quite a bit. China panicked about their birth rate, instituted draconian measures, and now has a significantly negative birth rate, to the point that they're going to have a huge demographic swell of the elderly, followed by a massive drop as the old generations die off.
This will basically just be a drop in the bucket, no pun intended. It's going to be way too expensive to really have any impact in any place but the more developed world, and those are the places that have birth rates below replacement level.
If this doesn't require the Y chromosome, then it could pave the way for female-only reproduction.
I'm male, but I have no qualms with the continuation of our species being without the Y chromosome (males). It's not an affront to my gender identity to wonder if the future would be better off that way. I'm not talking about killing off the males; just not making any more.
We should keep some male sperm frozen behind a glass door: "Break in case of extreme reproductive emergency."
"A few years of unsuccessfully trying to have a baby would change your opinion and attitude on the subject."
It's just hormones pumped into your body by your genes who want to replicate. Since we know that, you can easily overcome the need, since it's not _you_ wanting this unpaid job for decades.
Sorry but I believe that its in humanity's best interests that we shouldn't try and work around the little natural selection that we haven't already circumvented.
This is very cool and could potentially be extremely useful in animal breeding for livestock, pets or conservation biology. Basically, differentiate stem cells into eggs and sperm, cross, differentiate the new stem cells and repeat. A cool thing in animal breeding is that this could overcome species barriers, so traits could be introgressed by crossing species where the first generation offspring normally would have been sterile.
I can't need to stop reading these post. Now where did I put my soma...... ?
Millions of babies without fathers is just what the world needs.
Sex bots? As soon as a robot can kill a spider in a bathtub, it's all over for penile-Americans.
Good, by the time the machines rule humans, we'll have all of that information on how to clone human batteries ready for them.
All those moments will be lost in time, like tears in rain... time... to... die...
The 3rd-wave feminists need men urgently as the suppressed class that works for them and fulfills all their needs. As none of them have any actual skills besides grandstanding and claiming to be victims and bossing others around, they would just die on their own, like any other parasitic life-form.
Of course, they do not want to pay with sex for all that either, so I really do not see why they are opposed to sex-bots and porn in the first place. May just be a result of general stupidity and inability to connect causes and effects.
Most ACs are not even worth the keystrokes to insult them. Be generically insulted by this and ignored otherwise.
You assume humans are rational. Most are not and are great big narcissists in addition. Those with reproductive problems that are rational refrain from giving their children even worse problems than they themselves have and adopt or do without children.

A woman at that point could possibly get sperm from a man without his consent or knowledge and then use that child as a golden ticket against them.
There was a Law & Order episode about EXACTLY this!
Third-wave feminism is pretty much dead nowadays, and 4th wave is having a very hard time figuring who they should hate.
"Transparent" is a shit show that trades on every stereotype going. A man in drag is NOT a transsexual.
Never heard of a vasectomy, have you? If you don't want to father kids, then it's your responsibility to ensure it doesn't happen, not hers.

There are SEVEN BILLION of us already here, and we are adding TWO HUNDRED THOUSAND more people, EVERY SINGLE FUCKING DAY!!!!
ENOUGH!
I think I have identified the problem :-)

Sounds like a good argument against abortion too.
"His name was James Damore."
I hope you're right. The joy of being a pessimist is that you get pleasantly surprised when the worst doesn't happen
Well, the planet doesn't need more humans, but each generation of humans needs the next generation of humans to take care of it in their senescence. Not that there's likely to be a shortage of new humans in any case.
On the flip side curing infertility isn't going to make any measurable or perceptible difference in population growth. For that there are two extremely powerful and effective cures: (1) raising the level of economic security so people don't try to procreate their way to a secure old age and (2) raising the status of women to the point where they have other things to do beside take care of children (important as that may be). If overpopulation bothers you, that's where your attention should go.
So you may as well cure infertility. Yes, there's a cost to overpopulation, but there's a benefit to having a next generation too; but neither is going to be impacted by helping a handful of people obtain the benefits of having children.

Yep - all those fundies who are against abortion need to get their tubes snipped (male AND female. We don't need any more Duggar clans.

A few successes might change yours.
Don't waste your vote! Vote for whoever you want, unless you live in a swing state it won't matter anyways
In the developed world, birth rates are fairly stable (ie every 2 people have less than 2 babies each on average). So the only over-population problem is people in poor countries breeding like rabbits.
I can grow sperm!
No dish required!
Chas - The one, the only.
THANK GOD!!!

Actually all those *women* who don't want abortions should get their tubes snipped - men get no say in abortion.

If she doesn't want to have kids, then it's her responsibility to ensure it doesn't happen - I don't know when she ovulates, she does.

Well, I knew that the Chinese have some exotic things on the menu, but this one is a bit novel, all the same.
Nobody knows whether it's possible.

Sure men get a say in abortion - you don't make a baby, there's no abortion. Or did you miss sex ed? :-)
"Transparent" is a shit show that trades on every stereotype going. A man in drag is NOT a transsexual.
You miss the point - even if she wants kids, you still have the option of not having any by a simple snip-snip. After all, you might not know when she ovulates, but you know when you cum, and the potential consequences. And you know what we call people who use ovulation date as a birth control method? Parents.

Okay, that has got to be one of the stupidest AC comments I've ever seen. I'm not even going to reply to what you wrote except to say that if you want a reply, log in. Otherwise, DIAF :-)

The sentiment is appreciated...

Is that because there's so much porn on satellite TV?
I was disappointed when I realized they were not growing Spam.

Even if I want kids, she still has more options than I do: she can snip, use an IUD, take a pill, refuse sex-without-a-condom, take a morning after pill or, as a final resort, terminate.
She has three more options than I do, so why are you stating that's its the guys responsibility? Are you presuming that all women are too stupid to practice birth control, hence the guy must practice abstinence? Why not ask the female to practice abstinence?
I'm a minority race. Save your vitriol for white people.
Bullshit. You are responsible.for your sperm. If you don't want kids, it is only your responsibility because it your body. Same with women, it is their body, their choices, if she doesn't
Why should someone else be responsible for your fertility? Also, if you can't control yourself, go fap yourself looking at porn. Problem solved. Or get ready to pay child support for the next couple of decades. Your decision. A woman isn't just a bucket for your cum. You sound like a horny teenager. Grow up, because right now you don't need to worry about birth control - your personality is more than sufficient.

You deny women agency over their own body. If they get pregnant, you say it can't be their responsibility.

Jokes on you. Since this year I've got custody and she's paying me child support. By what you just said, if she didn't want to be on the hook for child support she should have just kept her legs closed or used a vibrator, right? She should have controlled herself if she didn't want to pay child support, right?
I'm a minority race. Save your vitriol for white people.
Fuck you, troll. I also said that women have control of their body and their choices. Grow up (oops - too late). The courts will say it's both your responsibilities, so both of you pay, and that's how it should be.
And yes, if she didn't want this to happen, she could have told you to go screw yourself instead of sleeping with you. Or just demonstrated better taste in men.

That s quite a change from your oft-pronounced usual opinion. You always say it's the man's responsibility for kids, you even repeat that opinion in this thread.

This may or may not come as a surprise to you, but women in general have the freedom to sleep with whoever they want to. Trying to slut-shame them when they favour men like me is bound to backfire.
Besides, I've been married more than once, to beautiful and highly qualified women. It's a fantasy of yours that someone like me begs for sex.

I never said that, asshole. I said that if a man doesn't want kids, he has to take precautions, same as the woman. The two are not mutually exclusive.
Never said anyone couldn't sleep with anyone else, except kids and people who don't want to sleep with them. However, your attitude that it's the woman who should bear all the responsibility is misogynistic. That you don;t see it just means that you're an asshole.

This is my post that you disagreed with upthread:

Good thing slashdot doesn't allow editing of posts, it's still for you to read.
Never said anyone couldn't sleep with anyone else, except kids and people who don't want to sleep with them.
No, you hypocrite, you just judged them for their sexual choices when you said:
Or just demonstrated better taste in men.
You want to be judged for your sexual choices? You think slut-shaming I a good thing?
However, your attitude that it's the woman who should bear all the responsibility is misogynistic. T
I never said nor implied that. I said women have more options. I never said that it's the women's responsibility, I repeatedly pointed out that the women simply have more options. That's a fact.
hat you don;t see it just means that you're an asshole.
I might be an asshole, but I get laid whenever I want to, usually with whoever I want to. Maybe it's because I don't go around judging others. Your bitterness over sexual freedoms suggest that perhaps you should get out once in a while, because it's usually those people who have unsatisfying sexual lives who are the loudest in denouncing other people's sexual lives.
You've spen this whole thread telling me how poor my sex life must be, or how poor a females taste must be to want to sleep with me and I never, until now, even responded to those remarks. You're displaying an insane amount of frustration.
oh, yeah, BTW I had satisfying sex last night, and am preparing to receive satisfying sex now. Remember that, while you type out your frustration into a vitriolic response to this, all alone, later tonight while I am getting it on :-)
I'm a minority race. Save your vitriol for white people.
Same as the rest of your post is also garbage and lies.
