SIZE & how it effects gender of offspring

[thadjock]

so a while back i read this totally scientific report that claimed guys with big diks father more boy babies than guys who are smaller than average.

it seems to be supported by my own family, my dad is big and he had all boys (4) who are also big. with two different women, so that would suggest it was more determinative of my dad's side than the female? i know 2 women and 4 kids isn't exactly a control group, but 2 of my brothers have 3 kids and all of them are boys too.

the study said it had something to do with the fact that "boy" sperm are more sprinters and "girl" sperm are more long distance swimmers, so when the semen is deposited closer to the egg, the boy sperm gets there first, but if they have a LONG way to swim (because the dude is short) they get passed up by "girl" sperm that swim more slowly but have a longer viability in the vagina, so more of them survive to reach and fertilize the egg making a girl baby.

anybody want to offer supporting evidence from their own families or refute this claim? also if any fertility specialists out there have an opinion i'd like to hear it.

I had never heard this but its an interesting idea. If the boy sprinters/girl long distance swimmers is true I don't see why the idea wouldnt be.

You may wish to check out http://www.lpsg.org/116182-evolution-and-the-penis.html and/or read "Sperm Competition" and other books where evolutionary biologists argue such theories.

Supported by my close friends family. He has 2 other brothers, and although I never saw any of his brothers cocks, other than a few nice buldges here and there, I did see his which is/was the biggest dick ive ever seen.

ack. don't make me think about my dad's package.

ew.. i have brothers... ohh eewwwww

Wow!!!! If that's is true (which I'm highly skeptical) that is the most sexist thing I read in a long time. So now even before conception we can map out gender differences and gender roles?!?!?!?! :sigh1: Boy, do we have a long road to equality.

sounds like a crock

We really gotta do something about the state of our public schools in this country.

I have seen this play out in real life. My uncle is one of four brothers (one is a half brother) and he only has one sister. That's 5 boys out of 6 offspring. That is nothing like the 50:50 chance that people say it is of a boy and a girl.

On my father's side also he has three brothers. I am my father's son (duh) and he also has another son. That's 2/2 offspring that are male.

This theory seems to make sense. And is much better than my friend's theory that "if you dominate the woman, you will have a boy" The flipside of that according to him was that if you let her be in control, you will have a girl :tongue:

NOTE: I am not claiming to know nor do I want to know the 'measurements' of any of the persons mentioned above. I am just pointing out the statistical anomaly.

Also, I am not saying that this rule is "hard and fast" :wink: just that I think men with larger penises are more likely to sire boys.

The part about the difference between boy and girl sperm is interesting.

Reality TV - News - Germany plans sperm race reality show - Digital Spy

why can'twe get this kind of reality TV over here?

I don't know, but my dad was hung, had 2 sons. I'm hung and have 3 sons. a lot of women think this way also. last weekend, the female bartender asks me if I have kids. "i have 3 sons." " you must be hung. how long you been married?" "30 years" "yeah, you are hung." even if you have no kids, and have been married for awhile, women assume you are hung because your woman has not strayed from her Mr. Goodbar. a few years ago a gal was trying to talk my wife into a swinger's group, my wife politely said she wasn't interested. when pressured she said she doubted whether she would find a bigger cock than mine, or somebody who knew how to use a big cock better than me among the males in the group.

My adviser in college did alot of work in human sexuality, as did I. She showed me several studies that concluded that male sperm in fact do swim faster than female sperm. The reason for this is that since sperm are so very tiny, that the difference in weight between the Y chromosome and the X chromosome allows the male sperm to swim faster. While she did not do any studies linking this information with penis size, she did do studies linking it with the timing of conception and found statistically significant results. If you haev sex prior to ovulation, you are more likely to conceive a female. If you have sex after ovulation, you are more likely to conceive a male. The reason for this is if you have sex before ovulation, the male sperm get to the falopian tubes first, find no egg, and die from the hostile environment. The female sperm take longer to get to the falopian tubes, so by the time they get there, the egg has entered the falopian tube and a female is coneived. If you have sex after ovulation, the male sperm get to the falopian tube first again, but this time there is an egg there to fertilize and male is conceived. Given all of this, I dont see any reason why being hung, especially length, would have a statistically significant impact on the gender of the fetus. It is not going be 100% but a statistically significant result isn't 100%, just significant enough that it is more than just random chance. I think I may contact my adviser and see if she would be interested in doing a study on penis size and gender of conception due to weight differences in male and female sperm.

i can provide samples :biggrin1:

First of all, no amount of anecdotal evidence provided by members is going to mean a thing. You absolutely *cannot* rely on a self-selected group with no controls, no statistics, no rigor in the methodology, and highly influenced by confirmation bias.

Second, the "it makes sense" argument doesn't hold water (or sperm) either because the dash to the egg is not as straightforward as one would imagine. Recent research confirms that sperm go metabolically quiescent for a period halfway through the fallopian tube where the types of proteins change to bathe the sperm in fluid rich in sugars to help them on their journey.

You'd have to reference the original study and review the results. A "totally scientific" study just doesn't cut it nowadays. One can get any result one wants cloaked in scientific sounding jargon to confuse the public if the authors have ulterior motives.

Not that it's *not* true ... but anecdotes and trivialized handwaving of complex biological processes are not the way to determine the facts.

This theory to me doesn't seem as sexist as the evolutionary psychology stuff. (such as in this thread: http://www.lpsg.org/118557-are-women-whores-by-nature.html) Now THAT stuff is sexist! That and the kind of thinking that women can't do math as well as men, etc. etc... I still think you're my kinda person though! (I really like it when I find other people who agree with me on this stuff - we're so rare!)

Although I'm skeptical about size and how it affects gender of offspring, too. I just don't think that enough research has been done on the subject.

BTW, my dad has 6 brothers and 1 sister. Hmmm... I try not to think about the implications of that though. Not so sure I want to think about my grandfather in that way!

it's not? i think that's all it takes to get ANY new drug approved by the FDA.

oh yeah and a suitcase full of cash.

most so called "independent studies" are funded by the companies or industries trying to get the patent on something.

anyway it's a big dik site, we're not trying to write a thesis or anything here. i was just wondering if anybody else had family stats that fit the model.

 

[Boondocksaints]

This is a ridiculous theory. If this were true, it would also mean guys who shoot far are also more likely to have male offspring in comparison to guys that just dribble.

 

[Incocknito]

I believe the point is that

a long penis that also shoots far

Ends up closer to the egg than someone who shoots the same distance but has a shorter penis.

So this is not strictly an issue of how far you can shoot, its depends also on how long your penis is.

Also I think that men with large penises have more testosterone and perhaps more "male sperm" than "female sperm" which further increases the chances.
