Human Sperm Produced In the Laboratory

duh P3rf3ss3r writes "The BBC is carrying a report from a team of researchers at Newcastle University who claim to have developed a the first 'artificial' human sperm from stem cells. The research, reported in the journal Stem Cells and Development, involved selecting meristematic germ cells from a human embryonic stem cell culture and inducing meiosis, thus producing a haploid gamete. The authors claim that the resulting sperm are fully formed, mature, human sperm cells but the announcement has been greeted with mixed reaction from colleagues who claim the procedure is ethically questionable and that the gametes produced are of inferior levels of maturation."

Re:So what? (2, Funny)

interkin3tic (1469267) | about 5 years ago | (#28626367)

And you almost generated humor there. If you had a lab maybe you could have actually been funny.

The big deal though is, I would assume actually several things

1. It's interesting enough that we can generate them in vitro. How sperm are made is better known than some other cell types, but now even the parts we don't know can be more easily studied, since you can watch it in a microscope easier. Changing conditions to determine what sperm need to develop is also going to be easier in a dish than it would to change conditions in a mouse testicle (I would assume, I've never tried.) For example, some big pharmecutical company could start a high-throughput screen of drugs on the process, they could identify some chemicals which would block the process and maybe make a male birth control pill. Maybe. There are many other applications for the technology too I'd assume.

2. We're close to curing some types of male sterility. If, say, you had testicular cancer or other... uh... trauma to your testicles that prevented you from generating your own sperm, this is a step toward that. You could take some of your cells (like skin cells), make them pluripotent (like embryonic stem cells), generate sperm from them, and then undergo IVF.

At least, a millionaire could. If he were willing to sort out the ethics of it for himself. Would be kind of stupid if you ask me, but so are a lot of things people spend their money on.

blueg3 (192743) | about 5 years ago | (#28626327)

It actually turns out that's not true -- if you had nothing but the DNA sequence, you could not (even in theory) construct a human from it. For one, the mitochondria organelles have their own genetics independent of our own. The organelles are inherited directly from the mother's cells. For another, how DNA is used and rendered into proteins, etc. is altered by chemicals that are carried along with the cell. If those are stripped away, information is lost.

Re:Er.... (1)

blueg3 (192743) | about 5 years ago | (#28626481)

It's not cloning, because it's a haploid cell. Cloning requires that an embryo be formed from a diploid.

In other words, in a clone, the clone is a genetic duplicate of the parent. In this procedure, a cell is induced into meiosis, which creates two half-sets of DNA. This is combined with a half-set of DNA in an egg, just like in non-lab sexual reproduction. With the genetic juggling that goes on during meiosis, it wouldn't even be cloning if the sperm and egg were from the same individual. (I guess that would be F1 self-hybridization, which would frankly be pretty creepy, but not as much as cloning.)

Re:Er.... (0)

Anonymous Coward | about 5 years ago | (#28626513)

It's not cloning if you're producing sperm from a stem cell. You would still have to mate the sperm with an egg, and even if you were able to produce an egg from that same line of stem cells (nothing in the article suggests this), the resulting offspring would not be identical to the parent. So no, not cloning.

Re:Er.... (3, Interesting)

Defakto (813358) | about 5 years ago | (#28626281)

What's unethical about this?

The use would be the unethical portion and science because there is no guarantee that what results from the sperm-egg coupling using one of this would be a viable, working person. Religious and moral beliefs aside I think this is a great thing. It may not now help us understand how our bodies work but it may lead to it in the future. I'm a firm believer that cloning has a huge potential in the long term for helping out humanity as a race.

Re:Er.... (1)

Speare (84249) | about 5 years ago | (#28626405)

"What's unethical about this?"

A fair question, but the answer is obvious. The scientists think the product is perfect, but what if it's not? At this stage of our understanding in the process, you can't ethically ask some woman to bear a potentially deformed or unviable fetus. We have no idea how it would go. Even if it were to survive the gestation, we may only discover after a year or two that the child has some debilitating problem: now we've created a human being from scratch who must die prematurely, and the parents and caregivers would also be heavily affected in the negative.

Re:Er.... (1)

CannonballHead (842625) | about 5 years ago | (#28626773)

Not to mention that we've decided it's worth experimenting, essentially, on human babies. Not even on human embryos or human fetuses or whatever, now we are talking about human kids. Outside the womb. This really does seem like a downhill slope. I'm against abortion in the first place, but to "grow" a human to see how it turns out?

There are organizations with vehement supporters for "ethical treating of animals" and "no animal testing" and yet we are willing to start testing, uh, human farming... or something.

Maybe I should start a "Humane Treatment for Humans" organization. And actually define what a "human" is, since nobody wants to define that. Until it comes down to when someone ELSE wants to define it in a way that personally affects you.

Re:Er.... (2, Insightful)

Altus (1034) | about 5 years ago | (#28626891)

Of course regular parents take this chance every time the conceive a child.

I'm not sure I see the ethical dilemma in using this technology to allow a couple with fertility problems to reproduce. Sure, in this case you don't know what the odds are, and its possible something will go wrong that couldn't go wrong normally. But everyone who has a child takes the chance that the child might be deformed or sick or die shortly after birth. Its part of the human condition.

Re:Er.... (1)

julesh (229690) | about 5 years ago | (#28626419)

What's unethical about this?

Not saying I believe any of these to be valid, but these are the concerns people are likely to have:

1. "Playing god."

There is a major taboo with messing with our reproductive systems, and every time any major advance in reproductive science occurs, there are religious arguments against it. Compare it with IVF and birth control, both of which attracted a lot of attention from a number of religions and are considered unethical by many.

2. The technique enables a major change in the reproduction of our species. There does not appear to be any reason why the stem cells would have to come from male donor; this tecnique could result in a child with two female biological parents. Potentially even only one female biological parent. I can understand why this would worry a lot of people.

3. A child resulting from the use of this technique is quite likely to have a biological parent who never actually lived. This is a rather peculiar potential outcome, and may well worry some people.

I don't personally see any of these as a serious problem, as long as the technique is used sparingly. But you can bet there are a lot of people who find some or all of these ideas repugnant.

Re:Er.... (1)

CannonballHead (842625) | about 5 years ago | (#28626701)

4. You may end up with a "human" that is somehow not "human" due to strange things going on with the sperm that wasn't "naturally" produced and the egg from wherever. So now you have, in your mind, "produced" or "manufactured" an "inferior" human. Is "it" worth keeping?

If no, and killing "it" is allowed, then we've just legalized killing human beings because someone else deemed them not worth keeping around.

That is a pretty dangerous path to go down without some serious thought.

People get majorly upset with science allowing us to blow up the entire world and want us not to pursue weapons that would allow that, or at least keep them at bay. Is this so very different, from that non-religious "survival of society" standpoint?

If a woman gets your blood, then she can bear your children? Wow! This will be a great argument for deadbeat dads! Now they can truthfully say "I never had sexual relations with that woman."

Black markets for the blood of rich men . . .
Personal IP rights in your personal blood composition . . .

Wow, the world got more interesting on 7/08/2009!!!!

This could be a serious legal problem for men in the future. I'm not a lawyer, but based on what I've read the general guide is that if male reproductive material is used to produce a child, the biological father is liable for child support no matter what the specific circumstances are.

In the scenario mentioned by MarkvWI in his first quoted paragraph above, I don't think it is out of the realm of possibility that the man the blood was taken from could be held liable for child support.

Scientists can produce it in a lab? (-1, Redundant)

Oh, we just want to see what diseases we can thwart with stem cell research...lol...Riiiight buddy. Its obvious that the natural course of scientific examination of stem cells is to eventually make fake sperm!

And those of us who dont want tax dollars to fund this kind of shit...well I guess we just have to deal. Im sure glad I belong to the 'common goal' of misdirected ethics.

Interestingly, this opens the door to biological children from homosexuals couple. Sure it's been foreseen for a long time, still big big can of worm.

"...the announcement has been greeted with mixed reaction from colleagues who claim the procedure is ethically questionable and that the gametes produced are of inferior levels of maturation."

"No! YOUR synthetic gametes are at inferior levels of maturation!"

"Nu uhh! YOURS ARE!"

"SHUT UP!"

Not that we necessarily were, according to some...

If this procedure became easy/commonplace, it would greatly facilitate lesbian genertic reproduction of two women, vs. one woman and a sperm donor. Since the stem cell used to create sperm would be XX, all resulting children would be female. Interesting to think of a slight but perceptible shift to a significant female majority world population (or population in developed countries).

Possible consequences: less war; economic trouble for the TV and gaming industries; the slow decline of monster trucks; the world domination of Oprah and The View.

I for one welcome our new female overlords. Mistress. *grovel*

Finally, something to restore the balance.

So Clevon should regain full reproductive function (1)
