In a recent conversation with a friend, the question came up of whether men who are running high mileage are more likely to sire girls than boys. I vaguely remember a study showing this, and I thought that the disparity was pretty dramatic. Can anyone recall the title of the study and what the results were?
if you are training a lot you are more likely to have girls. i don't know what the study is called but in ethiopia and kenya runners have been known to take a year off to ensure a male child.
I did....final score: girls 3, boys 0
I know a couple of 2:30 marathoners with two daughters apiece and an aspiring 2:30 marathoner who just had his first daughter.
Here's the study:
According to latest studies most girls tend to be conceived by females. It is also reported that the figure for boys is fairly close.
I'll try and post the link but I believe that some of these females may be runners, although probably not during the actual event. (In some cases before, in many others after).
Evidence for males conceiving is fairly insubstantial, and the figures are likely to be even lower if running at the same time.
Hope that helps.
you stupid jackass. another troll just looking for a cheap laugh
Thank you.
It's a good point and you make it well.
Of course the position of the moon is also critical........
this statement here should tip you off as to the dubious credibility of this article:
"Of course, as you are already no doubt thinking, mum plays a role in determining gender, too. Perhaps, the strongest link between mothers and offspring gender has been discovered in women who suffer from toxaemia in pregnancy."
The mom does NOT play a role in determining sex of offsrping. All eggs provided by the mom carry an X chromosome. If a sperm carrying an X chromosome fertilizes the egg, the sex will be female. If a sperm carrying a Y chromosome fertilizes the egg, the sex will be male. The dad determines the sex.
I don't have any kids (that I know of) but a friend of mine in Australia who is a "serious recreational" triathlete has 3 girls.
Another friend of mine in Seattle who jogs about 3 miles a day has a girl (only kid).
Conversely, my own father, who was admittedly out-of-shape and not training at all when he married my mom, had two boys, me and my brother.
Alan Culpepper has a son, Cruz.
Bernard Lagat has a son.
Both are male runners above the recreational level.
I am a pretty serious runner and I just found out we are having a girl.

I was going to mention those guys too. Maybe elite male runners have more testosterone.
It didn't say 100% had females, there was a higher percentage. Of course there are still going to be elite male runners with male children.

So maybe triathletes don't have enough X chromozones to go around? ;-)

Hahahahahahhahahahahahahaha
Testosterone has NOTHING to do with the Y chromosome.
Ahhh you people are f***ing idiots.
I am a 2:31 marathoner, 15:20 5K'er and my wife is having a boy. However at time of conception, I was only running 40 or so miles a week.
My dad was a 2:30s marathoner, running around 90 miles a week. End result: 6 boys, 1 girl.
why is your name mendel?
Its true...most girls are born from females. However males are also born from females.
Unless you marry some fat porker the only thing guaranted is that if you have a boy he will probably be scrawny with a small penis. I saw a study one time suggesting that the better you are at distance running the smaller penis you have. Something to do with hormones. I'll post the study when I find it.
Trick questions...runners don't conceive b/c they never get any!
