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.
