Delayed Fatherhood May Be Linked To Certain Congenital and Mental Disorders 192

New submitter optimus_phil writes "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.'"

        Speaking of medicine, how much of that risk increase is due to the advanced age of the father, and how much is related to the extra medical procedures he was subjected to ? I would think a 50 year old father has underwent allot more CT scans, radiographs, MRIs, and has taken allot of genotoxic pills during his lifetime than a 30 year old father.

        About 1% of US cancers are linked to CT scans and the strong magnetic field of the MRI was proven genotoxic in mice.

          I would consider this influence very small, probably not even noticeable right now, compared with the risk due to the higher age of the father. It is a far cry from an 1% increase of risk (which is just a link, not a known causal connection right now) for cancer by the CT and MRI scans one gets during life, and the 50% increase in risk for autism, especially when we know already about the increased health risks for the child if the woman is 10 years older.

          And how much of it is because Aspies have difficulty with relationships, and get married later in life, after both their social skills and finances have improved? The correlation may be backwards. It may not be older fathers creating autism, but autism creating older fathers.

        I have a somewhat more optimistic view of the future than you seem to -- I do think we're heading for a low point in some areas right now, but I also think these things often go in cycles and that since most people are basically decent human beings we will learn to deal with the problems and fix them with time. There will be more later, but that's life.

        Personally, I wonder how much the kinds of health effects we're discussing here make a difference compared to the potential benefits of having parents who are a bit older. For example, if older parents tend to be more financially secure, they can probably afford a better home in a safer neighbourhood and a safer model of car. Maybe they can afford better educational toys or more books or to take their children to more places and given them more positive experiences as they grow up. More mature and experienced parents can also share the benefits of that experience with their children, perhaps giving the kids a head start in academic life or more emotional support when they have to deal with difficult situations.

        There's got to be some sort of balance here. Very young parents don't tend to do well by their kids, because they can't. Maybe they lack sufficient resources to care for them properly, and maybe they are still barely more than children themselves emotionally. On the other hand, relatively old parents tend to have kids with more health problems as we've been discussing, and obviously at some point in your life you can no longer mother a new child at all. The interesting thing to me is how to figure out what gives kids the best outcomes under different circumstances, so would-be parents can make informed decisions based on seeing the whole picture.

        I used to think this way too. But I think the one thing that stands out as irrational in your argument is "today." What is so bad about "today"?

        Go back a hundred years, and the chances of a lot of these things was significantly higher. Go back a few centuries, and most kids died in early childhood, many women died in childbirth, and most people who managed to get to adulthood faced much, much more harsh conditions than the vast majority of people would in an industrialized country would today.

        So, if you want to have a pessimistic worldview, and you think that's a good reason not to have a child, that's fine. But just be honest with yourself and admit that -- by that logic -- the human race should have become extinct a long, long time ago. It has to do with your philosophy and beliefs, not some terrible conditions that are supposedly so much worse "today."

        As far as we're concerned, my s.o. and I, the best time for fatherhood is never, as we reckon giving life today isn't really a gift.

        Life is neither a "gift," nor is it some sort of "punishment." It is simply life. Frankly, while I myself had thought the same thoughts in the past, I have since realized the hypocrisy that often comes with it. If so many things are so terrible in the world today, why not commit suicide right now? If life is "suffering" and having a child is only to bring a new life into a world of suffering, why do you yourself continue to exist?

        And if your answer is simply, "Well, things are getting worse... so I'm still okay, but my child would have a terrible future," then please see above and read some history books. Miraculously, millions of those people in the past didn't commit suicide either, despite the horrendous suffering in their world -- and they even chose to bring more kids into it.

        Don't get me wrong: I have no problem with people who decide not to have kids for whatever reason. I think fewer people probably should have them, since it's a significant responsibility, and people should think about it seriously. But try to be honest with yourself about what your motivations are.

        (Otherwise, you end up going down the bizarre irrational path of philosophers, like David Benatar [wikipedia.org] who advocate that the human race commit collective suicide (see Benatar's book Better Never to Have Been: The Harm of Coming into Existence), but the philosophers themselves -- despite horrendous suffering in the world, and their likely contribution to more of it every day -- somehow decide that they should themselves continue stay alive. Life really must not seem that bad to most people who make this argument, if they're still living in this world.)

      • FFS, adopt. Unless your genetics are so precious that they must be preserved, why would you want to fire that old cannon anyway?

  • There are two living grandsons of John Tyler [dailymail.co.uk].
    Which proves nothing, because this sort of discussion is not about proving things.
    What I want to know about the research is how much dope the old coots under consideration did. I submit that the quality of life lived may have as much impact as the quantity, but not quite get teased out as well in the research.

      This type of health research is largely about probability. It is not that far distant from research that shows that cigarette smoking is generally a really bad idea from a health perspective. You can't disprove that idea solely by showing a 70+ year old heavy smoker who managed to not get lung cancer, but you can support it by showing millions of people who died of it at a much younger age than that without a family history of it.

      Similarly, we know that some conditions with poor outcomes track with t

    Personally I view a significant cogitative or social defect that has a one-percent chance of ocurring to be unacceptably high. That's several kids in each class year in any medium-sized elementary school.

    So, yes, I would consider an increase from 1% to 1.5% to be important. Granted, reducing the base probability would be far more useful than dealing with the age-related increase, but either way, these are large numbers compared with, say the usual "cancer risk increases by 5x" headlines which ignore the base risk being maybe 1E-6.

    Better able to provide for offspring due to more career development
    Higher likelihood of genetically fucked-up kids

    Congratulations, DNA, you win the King of All Trolls prize.

  • I guess there's some subjectivity in calling something "very small", but I'd call a 1 in 100,000 or 1 in 1,000,000 chance of a disorder to be "very small", not 1 in 100.
