May 3, 200618 yr http://www.myfriendslover.com/shemalelover/sept21/images/16.jpg Great your just on time! another thread fucking derailed by transexual porn. Im sick of seeing tits (thinking hmmm) scrolling down then getting my screen hit with a giant cock. Its not funny! :wow:
May 4, 200618 yr I wonder if I can lactate if I inject myself with enough estrogen :O_o: You will grow boobs. I'm not even going to say my opinion of this thread because it is rather obvious.
May 4, 200618 yr for all the fuck tards who dont know males are female UNTILL we get a special chromozone that makes our dick. Then when puberty comes, out body sends out a signal NOT TO GET BOOBS. Female horomones send the WE NEED BOOBS message out. I think the element that causes that is estrogen, so if you smoke pot that increases your estrogen levels and might cause you to get some small boobs. dr. player1 has fucking spoken to the greenhorns. p.s. i am 14 years old bitch, go to med school or something.

May 4, 200618 yr i placed the title of this thread directly into google: To tell you the truth, nobody really knows. The best explanation I've been able to find (and frankly it doesn't explain very much) is that nipples aren't a sex-linked characteristic. In other words, nipples are just one of those sexually neutral pieces of equipment, like arms or brains, that humans get regardless of sex. As you may know, every human being gets a unique set of 23 pairs of chromosomes at conception. These fall into two categories. One pair of chromosomes determines sex--the XX combination means you become female, the XY combination means you become male. The other 22 pairs, the non-sex chromosomes (they're called autosomes), supply what we might call the standard equipment that all humans get. These 22 pairs constitute an all-purpose genetic blueprint that in effect is programmed for either maleness or femaleness by the sex chromosomes. The programming is done by the hormones secreted by the sex glands. For example, the autosomes give you a voice box, while the sex hormones determine whether it's going to be a deep male voice or a high female voice. Similarly, the autosomes give you nipples, and the sex hormones determine whether said nipples are going to be functioning (in females) or not (in males). One interesting consequence of the developmental set-up just described is that during the very early stages of fetal life, before the sex hormones have had a chance to do their stuff, all humans are basically bisexual. Among other things, you have two sets of primitive plumbing--one male, one female. Only one set develops into a mature urogenital system, but you retain traces of the other for the rest of your life. It's tempting, therefore, to say that male nipples are yet another vestige of your carefree bisexual youth. Trouble is, male nipples are hardly vestigial. They're full-sized and fully equipped with blood vessels, nerves, and all the usual appurtenances of functioning organs. Why this should be so nobody knows--in some other mammals, such as rats and mice, male nipple development is completely suppressed by the male sex hormones. (Incidentally, don't start thinking that at one time our human male ancestors must have suckled their young. So far as anybody knows, male lactation has never developed in any mammalian species.) Human nipples appear in the third or fourth week of development, well before the sex characteristics. (The sex hormones start to assert themselves at seven weeks.) As many as seven pairs of nipples are arranged along either side of a "milk line," a ridge of skin that runs from the upper chest to the navel. Normally only one pair amounts to anything, but on about one baby in a hundred you can detect some vestige of the other ones, usually on the order of a freckle. There are cases of women who ended up with an extra breast, which made them freak show candidates not so many years ago. Luckily today the women can avail themselves of corrective surgery while the rest of us can watch Jenny Jones. Anyway, both male and female babies are born with the main milk ducts intact--the gland that produces milk is there in the male, but it remains undeveloped unless stimulated by the female hormone, estrogen. Occasionally, a male baby is born with enough of his mother's estrogen in his body to produce a bizarre phenomenon known as "witches' milk," with the male glands, suitably stimulated, pumping away at the moment of birth. In the adult male, the dormant glands can still be revived by a sufficient dose of estrogen. Actual lactation is rare--only a couple cases have been recorded. But at least one writer (Daly, 1978) has suggested that the "physiological impediments to the evolution of male lactation do not seem individually surmountable." Meaning we may yet see the dawn of the truly liberated household
May 4, 200618 yr Ohis Moment of Science will answer a question that must have been gnawing at you since you first noticed that human males have nipples. What genetic glitch left human males with female features? Male nipples aren't exactly a genetic glitch: they are evidence of our developmental clock. In the early stages of life from conception until about 14 weeks, all human fetuses look the same, regardless of gender. At the tender age of 14 weeks post-fertilization , genetically-male fetuses begin to produce male hormones including testosterone. These hormones turn the androgynous fetus into a bouncing baby boy. Here's where the developmental clock comes in. By 14 weeks, when the hormones turn on, the nipples have already formed. So, while our male fetus goes on to become a baby boy, he keeps his nipples, reminding all of us that people, male and female, started off the same way. In most men, the nipples really don't change after this point, but some men can develop a condition called gynecomastia. In gynecomastia, the fatty tissue around the nipple develops and eventually appears similar to a female breast. This can occur whenever the testosterone level is lowered by medications, such as those that treat prostate cancer, and by natural hormonal changes due to obesity, adolescence or aging. Luckily, most of us don't worry too much about male nipples, so men never have to worry about finding swimtrunks and a bikini top that fit. (straight up from a science site: http://amos.indiana.edu/library/scripts/nipples.html) BULLSHIT, we gave the bitches the nipples so we could look at them. We had them first, so the real question should be. Why do females have nipples. And i want my Rib back too. (omfg bible)

So you're saying little boys have vaginas until puberty?
May 4, 200618 yr So you're saying little boys have vaginas until puberty? lol^^ you kno the dudes with a vagina and a dick are the lucky ones.. lol imagine fingering yourself and wanking off at the same time!! :naughtyd:
May 4, 200618 yr BULLSHIT, we gave the bitches the nipples so we could look at them. We had them first, so the real question should be. Why do females have nipples. And i want my Rib back too. (omfg bible) hey man, dont blame the bible, this is science stuff. i dont think your soccalled "god" has anything to do with it
May 4, 200618 yr Actually you are wrong, the fetus sex is determined at the moment of conception. At 14 weeks the fetus of a male and female are exactly the same, however after this time the males hormones and females hormones begin to develop. Indeed, you are right, I did indeed mean to say what you just said, but either way, the point remains that the foetus grows as a girl until 14 weeks as you said. Chromosomes, the female egg carries XX chromosomes, sperm carries XX or YX. X = female Y = male Y chromosome is dominant, so the sex is chosen at birth depending on wether the sperm chromosomes are either XX or YX.
May 4, 200618 yr hey man, dont blame the bible, this is science stuff. i dont think your soccalled "god" has anything to do with it Maybe you should respect my beliefs because I'm respecting yours. If you don't believe in god, i don't give a fuck, don't tell me I'm wrong just because i don't believe in the same things you do, or don't.
May 4, 200618 yr lol^^ you kno the dudes with a vagina and a dick are the lucky ones.. lol imagine fingering yourself and wanking off at the same time!! :naughtyd: would they be able to get themselves pregnant? :X
May 4, 200618 yr why adds to the question.. Why does nihilarth or whatever his name is have huge nipples? Why is he covered in blubber? maybe for protection? Dun dun..!!!!!! Damn if I still had it i would post my edited pic.. I posted nih and then theres like scientists sucking his nipples :gaykeke: I don't mean the nih on this forum!! Or do I... DUN DUN DUN (again)!!
May 4, 200618 yr Maybe you should respect my beliefs because I'm respecting yours. If you don't believe in god, i don't give a fuck, don't tell me I'm wrong just because i don't believe in the same things you do, or don't. your right, i apologize :happysad:
May 5, 200618 yr Chromosomes, the female egg carries XX chromosomes, sperm carries XX or YX. X = female Y = male Y chromosome is dominant, so the sex is chosen at birth depending on wether the sperm chromosomes are either XX or YX. erh...we only get one chromosome from each parent; egg carries one X chromosome, and the sperm brings either one X or one Y chromosome. the rest is accurate though. bio knows his biology (kind of)!
May 5, 200618 yr would they be able to get themselves pregnant? :X No. Either one is fully developed, and the other isnt, or neither are developed.
May 5, 200618 yr erh...we only get one chromosome from each parent; egg carries one X chromosome, and the sperm brings either one X or one Y chromosome. the rest is accurate though. bio knows his biology (kind of)! Well yes, we do only get one from each, but there is 2 in each. Since Y is dominent, that chromosome gets chosen over the X.
