HealthDay News– Children who grow up in a home without a biological father have sex at a younger age than children raised with their Dad in the picture, and a study now offers a new explanation for why this is true. While previous research focused on environmental factors, researchers in this study, published in the September/October issue of Child Development, focused on genetic influences instead. “Our study found that the association between fathers’ absence and children’s sexuality is best explained by genetic influences, rather than by environmental theories alone,” study author Jane Mendle, an assistant professor of psychology at the University of Oregon, said in a news release from the Society for Research in Child Development.
Mendle and her colleagues looked at more than 1,000 cousins aged 14 and older who took part in the National Longitudinal Survey of Youth.
The more genes the children shared, the more similar their ages at first intercourse — regardless of whether or not the children had an absent father, the study authors found.
This finding, the researchers explained, suggests that environmental factors, such as childhood stress caused by having a single parent or watching their mom date, are not the only ones that carry an influence. Instead, genetic influence also can help explain the tie between absent fathers and early sex.
“While there’s clearly no such thing as a ‘father absence gene,’ there are genetic contributions to traits in both moms and dads that increase the likelihood of earlier sexual behavior in their children. These include impulsivity, substance use and abuse, argumentativeness and sensation-seeking,” Mendle said in the news release.
“The same genetic factors that influence when children first have intercourse also affect the likelihood of their growing up in a home without a dad,” Mendle added.

Funny, my girls have done just fine without a father. And the two teenagers are still virgins, btw. Our doctor felt some perverse need to share that information with me after their exams.
Just cause they virgins dont mean they not doing other things!
There was nothing perverse about it, he probably thought you might be interested in knowing. Obviously you don’t care and see the wrong on everything. Loser.
Michelle they probably just get fingered and give blowjobs, or take it in the rear…
Findings like this continue to miss the point. Epigenetics, by definition, are when certain genes are turned on or off due to environmental factors. There continues to be this fallacy that genes are what your born with; an idea that suggests both an inflexibility to adaptiveness – that we are somehow biologically pre-disposed to understanding the world in particular ways – and that biology is uni-directional – that environment doesn’t shape our biology. The opposite is true; we are born with epigenetic capabilities precisely to modify our biology and fine-tune our fit with the environment. This in turn, helps us to understand the correlation between genes and environment – a gene that might be turned on doesn’t make it a “gene for something,” it is a gene whose influence comes in the context of many other genetic modifications. Just like binary code, 0’s and 1’s mean nothing on there own, but many thousands of them make complex programs.
This, I think, far better explains the overlapping influences of missing dads and genes. The fathers, or some third variable related to the missing fathers, might be leading to the genetic changes in the first place. Certainly schizophrenia research has taken a massive turn with this lens, and more is to follow.
I don’t necessariyl agree with this. I grew up with my father in my life and I started having sex at a young age. It is sad how each new generation is more and more beyond their years. There is porn and sex everywhere we look. In ads, commercials, on television, and in movies. Society is so stuck on appearence and the fact of the matter is that sex sells. Its the society and environments that encourage young teens to be sexual.
Morgan seems to know what she’s talking about. This data probably suggests that from an evolutionary standpoint, certain genotypes have found reproductive advantage in earlier sexualized behavior when a father is not present.
I would think, just speculating here, that using sex to form ties to others at an early age gets a youngster a headstart on getting resources and expertise that he or she otherwise wouldn’t have access to.
Nature doesn’t care about prudishness, she just gets the job done. She makes the rules and does what she wants.
Why is teenage sex surprising? It was not too long ago, just a few generations when teenagers were married. Often girls, age 12, would marry. My wife could have been an example of that, she started puberty at age 9. She told me back when she was 11 or 12 if someone asked, she probably would have. She held on though until her first husband at age 17. I, myself, am an example, I started puberty at age 10, by 14, I was desperate, I ended up having sex for the first time at 14, with a girl I had just met, next to a building. I did not even know her name. In both of our cases we were also going to college at the age of 14. By 16 both of us had ‘4 year’ degrees. Clearly, there is a genetic link that would would have been supported until recently. It is only recently that society has decided that 12, 13, 14 years old is too young. For several reasons, some good and some bad. Largely, because we are told, ‘you have to finish school first’ and in some cases that is not some people are 30 finishing Phds. Then we wonder why there is an increase in autism and other genetic malforms, with people waiting that long?!? We wonder why children are looked at like a plague?!? If the world has really become that complex that it requires a H.S. education to function and a College Degree to get a decent job. We had better start looking at figuring out how to get that information completed by 13 or 14 and give those ‘young adults’ a real job.
So? What are the slut genes? Why did they leave that list out of the article?
Uh…obvious…where the fuck do you live and who is attending university at the age of 14?
I agree with L.boogie. I was raised by a single mother and first had sex as a HS senior. In Jr. High & HS, there wasn’t a lot of attention on sex, but rather crushes and “liking someone a lot.” Now there has always been sexuality in media, but it really has ramped up and come out of the shadows. It used to require some modicum of imagination, now it is in your face and blatent. Throw in the internet and young kids can get porn delivered on their phones via YouTube, where it seems to be a badge of honor to get attention. Hell, someone saying they had a topless photo of a girl in HS would have been fairly shocking in early 80’s. Now a video of a girl giving her BF a BJ would merit a *mild* commotion.
As an ironic aside, as I write this, they are showing a video on CNN of a toddler dancing to Beyonce’s “single women” video. Lots of imprinting going on there.
The headline sounded like hogwash at first until I got to this part of the article:
“…there are genetic contributions to traits in both moms and dads that increase the likelihood of earlier sexual behavior in their children. These include impulsivity, substance use and abuse, argumentativeness and sensation-seeking,”
Those traits fit me to a T (except for substance ABUSE, I’d never be that far down). My real dad was out of the picture when I was four, and if this article is true, then golly-gee…
Then again, I didn’t actually have full intercourse until my 17th birthday, but along the way, I’ve had plenty of play from show-and-tell with daycare girls at the age of four, to more graphic proceedings with gals in my old high school wood shop when I was sixteen…
This is total BS. I was raised my entire life without my biological father, or any father, for that matter. My mom has raised me on her own, my whole like. Which would be 22 years, so far.
The first sexual thing I ever did with any male, I did when i was 18. I didn’t have my first kiss ’til i was 17.
I think people assume these things. I never had a male figure in my life, so I never really knew how to interact with them. They’re like aliens to me. Well, not anymore, obviously.
The one thing that I have to say is why does it always have to be a negative affect as stated here, “impulsivity, substance use and abuse, argumentativeness and sensation-seeking?” These are all negative factors leading to the acts of early age sex.
This can only be interpreted as sex being a reaction to bad genes. I happen to find this appalling. It is our nature to procreate and enjoy the experience while doing so, and yes this is embedded in us at an early age, hint (Genes).
To misconstrue and and misinterpret sexual activity by the youth as being a product of parents prone to “impulsivity, substance use and abuse, argumentativeness and sensation-seeking,” is only the pure absence of intelligence and common sense thought. I must say that I am less worried about the kids having sex a young age and their parents genes than I am worried about the parents of the writer you wrote this article.

Anyway you look at it, children need a mother and a father – period.
