"New Scientist Magazine reports on findings that suggest that delaying fatherhood may increase the risk of fathering children with disorders such as Apert syndrome, Autism and Schizophrenia. The article reports that 'although there is a big increase in risk for many disorders, it's a big increase in a very small risk. A 40-year-old is about 50 per cent more likely to father an autistic child than a 20-year-old is, for instance, but the overall risk is only about 1 per cent to start with.' In other words: time to start mating before those tadpoles turn into toads."

As I understand it, the general trend in the West is towards people marrying and having children at older ages than previous generations. I wonder how many generations it will take before we would start to see any reduction in disorders correlated with the age of the parents?
I'm assuming that reproduction is still currently skewed in favour of young parents, as historically speaking, people lived shorter lives, so would've had less chance to become old parents, and there would be less opportunity for genetic traits related to longevity to be expressed.

When you consider that Western women are more interested in money than having children, Western men don't have money if they can't find work, and Western hiring practices favor giving jobs to women instead of men, the general trend in the West is toward extinction.

I see there is a lot of bitterness in your comment, which I'm just going to ignore. You should know that there are also men who don't want kids. I am intentionally childfree (as distinguished from "childless" -- a term that suggests lack). I always knew I didn't want to have kids and so I didn't. I got cured of my ability to cause infantile infestations in females 10 years ago, and it was probably one of the very best decisions I ever made.
As for extinction, we're growing our population exponentially -- if there is an extinction event for humans, I would bet it is much more likely to be caused by overbreeding rather than the few like me who choose to avoid the whole parenthood bit.

>> we're growing our population exponentially
That is no longer true. Population growth rates globally, and especially in Western countries have been dropping for years. In some countries, such as Japan, Russia, and Germany, it is negative.

-1 misleading.
For every child that's not been born in Japan, Russia, and Germany, a dozen have been born in India, Indonesia, Nigeria, or even China[*]
Population growth rates globally have been dropping, indeed, but whilst that rate remains above zero, even by the tiniest fraction, we've *still got exponential growth*.
The greatest shortcoming of the human race is our inability to understand the exponential function. (google that)
[* That dozen figure is completely pulled from arse, it's probably enormously higher, probably three figures, I'm just playing it safe.]

Imagine this equation:
y = 2x
As x (time), increases, y (population) increases. In this function the growth rate of y is ALWAYS above zero and constantly decreasing. This is a linear function, not an exponential one.

Nope, that growth rate tends to 0.

You are correct. The growth rate tends towards zero.
It also always stays above zero. And it is also not exponential.

+1 for childfree. Or "childfree by choice" when talking to people unfamiliar with the concept that some of us have no interest in making little clones of ourselves. Fortunately the term seems to be gaining some traction, so it doesn't need the full description so often.
We have more money left at the end of the month, and *way* more time all the time, than our peers who have sprogged. Then again, we're now living in a nett-NPG country, and most of our peers are not breeding either. (The last country I lived in was breederific in comparison.)

If you don't want people who choose to have children to be disparaging to you for your child free choice, then you probably should choose a different term than breeder. Most find it offensive.

If anything, a culture that discouraged reproduction, means that those that do reproduce would have a higher genetic disposition towards doing so. So even if there was a problem, it would eventually fix itself.
The real truth is that more educated and well-off populations tend to reproduce less.

The strongest and most telling correlation is with the level of education of the females. And that doesn't just hold between populations, but within them.

Wow, stereotype much?
Western hiring practices favor giving jobs to women instead of men
If we're talking about the US, those practices must not be working, because (according to the BLS [bls.gov], there are ~75 million adult American men working, and only ~66 million adult American women working. In addition, a big reason for the disparity is women delaying their careers to raise children - the US system strongly encourages one parent to go back to work as soon as possible after having a child, and because men on average earn more than women that parent is usually the child's father.
There's also a big difference between gradual population decline seen in some countries in Europe, and extinction. If a country was really worried about that, they could simply loosen up legal immigration and after a few years have a whole bunch of new citizens who are overjoyed to be there.

The women's movement was a boon to the rich. The labor market almost doubled with women's influx, and supply and demand drove down wages. The shame is, when women were first liberated, men should have been, too. In the early days, it was a woman's choice whether or not to work, but a man was expected to hold a job, and even today if you're a stay at home dad you're looked at in askanse, and it's gotten so that everyone, man or woman, is expected to toil away creating wealth for the rich.
A child, especially a young child, needs a parent at home. I would have loved to stay home and watch the kids; my kids and I were always close and I enjoyed being "dad" more than any other role I've ever had in life.
We need to go back to one breadwinner per family, and IMO it doesn't matter whether Mom or Dad stays home and who works. I'm old enough to remember when most women raised kids, and have seen that child care is harming our society. The only people who should need child care are single parents. The Unites Staes needs a labor shortage!!
Guys, let the old lady work, stay home and raise the kids. You don't need a McMansion and an F-150. I mean, is your self-worth so little that you need money to feel important?
Alas, the greedsters have killed any chance of you young folks ever having a better life.

That would only work if we used disorders as selectors. For example, if people with these disorders were disqualified from breeding. If there is no selector, there is no evolution ;)

Some selector is almost always at play. Even if just in sexual selection. While I'm sure age plays a part in the increase in disorders I also wonder how much the parent carrying the disorder is related to having kids at a latter age. People with social disorders, even if mild, may reproduce less likely or when they do, may reproduce later in life. There may be more than one thing at play here.

Natural selection is not just complex, but often counterintuitive. Consider the gene for sickle cell anemia and malaria immunity. If you inherit the gene from one parent, it confers immunity to malaria. If you inherit the gene from both parents, it confers sickle cell anemia. In malaria prone environments, it was common that everyone who survived to adulthood had one copy of the gene. Children of two such parents had a 25% chance of not getting the gene, and likely dying in childhood of malaria, a 25% chance of getting two copies of the gene, and likely dying in childhood of anemia, and a 50% chance of getting one copy of the gene, and maybe living to adulthood. The gene is a mixed blessing at best, but it is strongly selected for in malarial environments, and strongly selected against anywhere else.
It is quite possible that any particular undesirable genetic trait is being held in the gene pool by some desirable trait, to which it happens to be linked.
