Can You Choose Your Baby's Gender?: Boosting the Speed of Sperm

 

[pronatalist]

If this were true, wouldn't small penises have gone extinct long ago since they bred only females?

Uh, females reproduce too. They can find a male with somewhat different genetics. Genes can spread on the female side then.

 

[Incocknito]

To clarify:

We are not saying that men with large penises create only male offspring and that small penises only create female offspring.

We are supposing that:

A large sized penis has an increased likelihood of procreating a male offspring. By increased likelihood we mean more than the expected chance of 50%

I think there is some statistical merit in this from what I know personally.

Also from Guyjin's link:

"For a boy...Have sex on the day of ovulation or right before or after, when vaginal secretions and cervical mucus are most alkaline. Deep penetration, such as with your husband on his knees behind you, helps deposit the Y-bearing sperm near the opening of the cervix. Douching with baking soda and water can enhance vaginal alkalinity. Having an orgasm at the same time as or just before your husband also enhances alkalinity and helps transport sperm into the cervix, where the secretions are more favorable to boy-producing sperm."

sounds like a crock

Yay verily. I know a guy with a small penis and has sons, and a guy with a big one and has girls.

I have two sons and a daughter. Should I be getting a paternity test for my daughter?

Interestingly (for me anyway) My wife and I are pretty sure that both sons were conceived when I just grabbed her threw her down and banged the hell out of her. Our daughter on the other hand was conceived when we were slower and with her on top getting off first. There's a study I would like to see conducted.

 

[pronatalist]

What difference does it all make anyway? We shouldn't be trying to produce "designer babies" or "sex selection."

Whatever happened to welcoming babies to happen as they happen?

Once married, leave such matters as family size, child spacing, and what sex baby to have, up to God. So much simpler that way. No need for "birth control" when babies are welcome to happen as they happen. Of course people who practice no means of birth control, are more likely not to need infertility assistance either, as not only is it difficult for humans to "regulate" their birthrates, but it's hard to produce babies "on demand" as well.

If somebody asked me if I am hoping for a boy or a girl, I think the best answer would simply be "Both." If I had to choose, why not both? Or whichever the baby is would be fine. Of course I would like to know the sex before the birth, so as to plan which toys or whatever to maybe start buying. I probably wouldn't bother with the paint the room blue or pink nonsense. To know the sex before the birth, that isn't like opening a present before Christmas day. I see nothing immoral about "peeking" into the ultrasound or the doctor telling parents, unless there's a risk of "sex selection" abortions. A baby in the womb has no real right of privacy, but does have the right to live and grow.

So which sex is more likely, from some wild, spontaneous, in the camping tent, sex? A boy baby, since "wild" natural sex is more "macho," hence masculine? Seems a rather unlikely basis for determining sex to me, as that's more of movie logic, than how the real world of science and biology works.

What the fuck?

I thought children were produced by men. I didn't know every sex act was a threesome with God wanking himself off in a corner.

Children are produced by a male and a female and the sex of the baby is determined by chance.

Take yourself and God out of this thread. We are trying to keep it semi-plausible and with a firm basis in reality. Not in nonsense fairytales.

The difference it make is that the current view is that there is a 50% chance regardless. It would be interesting if this was not strictly the case.

Bull my wife is 5'5 Im 6'1 close to 8 inches I bottom out with her and I have a daughter so these facts don't mean shit

Babies are produced merely by "chance?" I think not.​

You believe in "chance?" That things happen a certain way, for no reason at all? Quite many people don't believe that, but that things happen for a reason, although we often don't know what that reason is, for quite some time.

Let me ask you a question. Do you have a computer in the room where you enjoy sex? Gasp! You're letting your computer get off, get its jollies, watching you have sex? But of course not. Computers aren't aware, or either don't care, about such things. Is God all-knowing or not? Then that means God is aware of those people who are having sex. There is no real privacy in that sense. But God is not a mere human. God doesn't "get off" at thoughts of carnal or procreative sex. Although a comparison between God and a computer, obviously has serious limitations, it can be perhaps a useful example of how awareness doesn't necessarily invade privacy. Consider computers of the future, that may be able to call automatically for medical assistance, if you fall down somewhere in your home, and can't get up. No more pricy medical alert pendants worn around some old person's neck. Could such futuristic computers be aware of people having sex? Possibly, but their software wouldn't make any big deal of it. Normal natural activity for humans. Most likely, the computer isn't going to contact people to let them watch, unless its owner gets off on such things. But should a copulating couple have a heart attack, then it would act to get them the help they need.

For God to be aware of people having sex, that's about as invasive to our reasonable privacy, as a parent changing a baby's diaper. The baby doesn't care, and why should you, if you aren't doing something immoral? It was God who created people naked, as Adam & Eve had no clothes in the Garden of Eden. It wasn't until they had sinned, and partaken of the forbidden fruit, that they themselves became aware, and ashamed of their nakedness, so then God gave them animal skins to wear.

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 don't think this is true. The distance the sperm has to swim is hardly determined by daddy's dick-size. It depends more on the internal build of the woman.

And, the gender of a baby is determined by so many factors, most of them still not understood. If an investigation would find out that bigger men do get slightly more boys that smaller men, it doesn't say that their cocksize is the cause!

 

[bigjpgh]

Do you have scientific evidence that proves that male and female sperms are always present in equal numbers?

We're not writing for the Lancet here, chill out.

Yes, in fact there is a plethora of scientific evidence that male and female sperm are produced in equal numbers, barring any errors in spermatogenesis. you have 46 chromosomes, 44 are twin pairs in that their partner is the the same kind of chromosome, sure with different genetic information but the same size and shape. Then you have 2 that are sex chromosomes. females always have two X chromosomes and males always have an X and a Y chromosome, the Y chromosome being about half the size of the X chromosome. (also the reason for many genetically linked recessive traits being 3 times more prevalent in men than women, like red/green color blindness). during spermatogenesis, the 46 chromosomes in a male are split in half with one matching set going to one sperm and the other half of those pairs going to the other sperm. for 44 of those chromosomes, you get sperm with 22 chromosomes that look basically the same, same size same shape. for the last pair, the sex chromosomes, one sperm gets the X and becomes a potential female producing sperm and the other sperm gets the Y and becomes a potential male producing sperm. It is always 50/50, barring some error in the process. Men always have full cells with one X and one Y chromosome, so when they are split, you always get one X sperm and one Y sperm. Any basic HS level biology test book will have plenty of descriptions and photgraphs and studies done to show how spermatogenesis works and why it does what it does and how we always end up with a 50/50 distribution of male and female sperm.

i think it means that despite your above average dik, u have girly balls that produce girly sperm....lol

There are about as many theories swimming around as there are number of sperm in an average ejaculate (from 50 to 100's of millions?) but no one has mentioned the relative health of the sperm. Some are simply more healthy and some, due to defects (no tails or whatever), just swim in circles. In addition to total number sperm and number of Y chromosome'd sperm, you have to look at each sperm's motility. Then you have to evaluate the female's Ph level as well as ovulation time. What? Isn't there a reproductive biologist on here to clue us in?
:smile:

I have heard the shooting vs. dribbling debate before and I believe it has been disproven especially with the belief that a woman (consciously or subconsciously) has the capability to "suck up" the sperm. Some theories say that is the purpose of the female orgasm. Of course, that leads to the debate of female promiscuity and how a woman can have sex with several different men but increases the chance of pregnancy if she has an orgasm with one of them.

The best goes on. . . . . . .

as they say, it's in the genes

Hmmm. I don't think I have read of that debate, but I would think that shooting sperm, makes pregnancy more likely. Perhaps the most significant factor in that, is that shooting likely involves a larger volume of sperm, as when dribbling occurs, there's less semen reserves build up, or less is ejaculated. And then, can the bigger "mess" or dispersion of shooting sperm, make it more likely that plenty of sperm gets to where it's needed, rather than merely pooling and running out later, during a trip to the toilet or whatever? Anyway, the wild shooting that can expel semen as much as several feet sometimes, it does serve some purpose, doesn't it? But obviously, complicating any theory, even dribbling semen has plenty of sperm in it, to make a baby sometimes, and it's not easy to measure more babies versus less babies, as so many factors would seem to be involved. Semen dribblers may have sex more frequently, which could coincide with a better match of fertility timing, making it seem like dribbling works as well or better, when in actuality, say if a man can rebuild sperm volume more rapidly than other men, it might not.

Isn't the official number of sperm in an ejaculate, around 500 million? Even a drop of pre-cum can have millions of sperm, one reason why early withdrawal is not considered all that reliable a means of "birth control."

 

[Guy-jin]

Based on the size of the X and Y chromosomes, I actually find it fairly logical to conclude that XX and XY sperm will travel at different rates because XX sperm are significantly more massive than XY sperm, the X chromosome being significantly larger than the Y chromosome. I also find it logical to further conclude that if this is the case, there is likely a natural means to prevent this from causing an over-representation of males, likely through XY sperm being more sensitive to the environment of the vagina. Therefore, I do think it's possible that depositing sperm deeper within the vagina might benefit XY sperm because they'd have less physical distance to travel and need to spend less time in what to them is a hostile environment.

However, as that link I posted points out, the conditions of the vaginal environment are the major factors in sex prediction, and I'd guess those conditions are far more important than where the sperm is deposited in the vagina.

 

[deleted298367]

You people are frustrating me with your examples.

Of course there's always exceptions to the rule. Just because you or your cousin's uncle's dad's grandson doesn't follow suit, it doesn't mean this theory isn't plausible. There's just as much evidence that it IS accurate.

a few comments

first, it would be nice if someone produced some science to support either side . . .

but I have always believed that big dicks increase the chance of boy babies. The way I heard it, the XY sperm swim slower than the XX but are stronger, thus the farther away from the target you are, the XX have an advantage, but the closer, the XY do.

While our personal experiences, as a recent poster noted, might not mean much, it is a fact that all the guys in my family have giant dicks, and it's boys all around . . . my father was one of three brothers. I am one of four boys no girls. my oldest bro has three sons no daughters, I have two sons no daughters, brother three is gay so he doesnt count. Oddly, i have an identical twin brother (with obviously the same dick size . . . something we could talk about in another thread some day) but he has one son and one daughter.

Next unscientific evidence point is that I have a friend who has the smallest dick I ever saw on a grown man. He has five daughters and no sons.

Also, there is a pretty common Spanish expression you use for insecure nerdy kind of guys that translates to "father of girls" . . . it's kind of the same as calling a guy a "pencil dick"

One more thing I thought I should (and everyone else should) say . . . forgive me it is off topic, but it is well related to the course of this thread . . . everytime Pronatalist opens his mouth I am amazed at how off point, one track, self righteous and moronic he sounds . . . I know religious people are often this way, but holy cow the minute i see his name my eyes roll so far back I get dizzy
