Why do males have nipples?

Will these windows change my original document?

All foetuses begin as females.

I don't know. I'm sure there's some biological/evolutionary reason. Someone also recently told me that there's some sort of female default thing with fetuses; not that they all start out as females, but that if something goes wrong then they often default to female. I'm not sure if that's true or how it works if it is, but I'll vote for that one.

They're mammals.

All fetuses begin as females (I believe).

I saw a show on Discovery or TLC or something a while back that was talking of men being able to breastfed. It happens a lot in tribes and stuff, where the only source of nutrition for a baby is breast milk. If the mother is unable to produce the milk, sometimes the father will get the "motherly" instinct or something and begin to produce milk. I thought it was strange, but I guess it could be true. *shrugs*

Sex toys of course. That's all that mine would ever get used for. Especially the pierced one

To have something extra for our girl-(or boy)-friends or ourselves to play with.

Gender isn't well defined in the early stages of development. Nipples develop before the sex differentiation DNA kicks in.

They're also great sex toys!

because they would look strange without them???

None of the above. It's to hold their shoulders down because they are always shrugging their shoulders because they don't know a damn thing.

to play with while having sex

I guess because the Y chromosome is not all that strong, is it now?

> All foetuses begin as females.


It really should be; "All foetuses begin sexless but having the equipment to become either one..."

conformity of appearances and sex toys. most definitely.

I think it's because all fetuses begin as female.
If not it has to be the conformity one.

all fetuses begin as females

Because we'd look weird without them.

Males have nipples because nipples develop on a fetus before the differentiation between male and female development occurs.

NEW YORK (Reuters) - Have you ever wondered why your teeth chatter when you're cold, or if you could really catch a disease from sitting on a toilet seat?

New York physician Billy Goldberg, pestered by unusual questions at cocktail parties and other social gatherings over the years, puts the public's mind at ease in his book "Why Do Men Have Nipples?" which hits the book stores on Tuesday.

"It's really remarkable how often you get accosted," said Goldberg, 39. "There are the medical questions from family and friends, and then there are the drunk and outrageous questions where somebody wants to drop their pants and show you a rash or something."

The book, subtitled, "Hundreds of Questions You'd Only Ask a Doctor After Your Third Martini," (Three Rivers Press), is co-authored by humorist Mark Leyner.

"People tend to know so little about their bodies as compared to their cars or their laptops," said Leyner, 49, of Hoboken, New Jersey. "When I worked in a pharmacy in Washington, D.C., people would ask me medical questions all the time. I was just a 22-year-old cashier at Rite Aid."

Chattering teeth is one way the body tries to generate heat.

When the body gets too cold, the area of the brain called the hypothalamus alerts the rest of the body to begin warming up. Shivering, the rapid muscle movement that generates heat, then begins. Teeth chattering represents localized shivering.

During the course of their research, Goldberg and Leyner found reports of gonorrhea, pinworm and roundworm found on toilet seats -- but catching something from it isn't common.

The authors discovered that an office setting might be worse for your health than toilet seats. Charles Gerba, a microbiologist at the University of Arizona, found the typical office desk harbors some 400 times more disease-causing bacteria than the average toilet seat.

Goldberg had compiled a list of nagging questions for several years before embarking on the book after meeting Leyner. The two met while working on a short-lived ABC-TV medical drama, "Wonderland," in which Leyner served as a writer, while Goldberg was its medical advisor.

BURNING QUESTIONS

Some of the burning questions answered in the humorous book include "What causes morning breath?" and "Why do beans give you gas?"

Goldberg says morning breath results from anaerobic bacteria, the xerostomia (dry mouth) or the volatile sulfur compounds (which are waste products from the bacteria). Other contributing factors to foul oral odor includes medication, alcohol, sugar, smoking, caffeine, and eating dairy products.

Beans contain high percentages of sugars that our bodies are unable to digest, Goldberg explains. When the sugars make it to the intestines, bacteria go to work and start producing large amounts of gas.

And if you're ever bitten by a poisonous snake, sucking at the bite to remove the poison, as often shown in the movies and on TV is not only ineffective, but could lead to an infection.

Instead, the bite should be washed with soap and water and immobilized. The bitten area should also be kept lower than the heart. Medical help should be sought immediately.

And why do men have nipples?

While only females have mammary glands, we all start out in a similar way in the embryo, the authors explain. The embryo follows a female template until about six weeks, when the male sex chromosome kicks in.

Men, however, have already developed nipples.

Now we know.

All fetuses begin as females.

To serve as pacifiers for babies when the mother is not available?

When you are being formed from an egg to a fetus you are not differentiated from male or female until after the nipples are formed. Women's hormones turns our chest into breast.

Sex toys.

To enjoy females!!!!

In fact, each male has some of female' hormones but in small quantity and vice-versa. So sometimes, there would be a genetic-fault, so males have small nipples, but it's not a big deal, because it can be treated by some medicines (antagonist hormones)!! But sometimes, males have extra-hormones of feminine hormones, here is the problem.

All fetuses don't begin as females, but before their gender is established, nipples are simply present as part of the common growth development process, as males in other animal species also develop non-functional nipples as well. It is doubtful that the human race will ever lose nipples in the Human Evolutionary Process. If anything males will develop the ability to nurse from their nipples, as more and more males are developing female-like chests in shape and fat deposits AND/or develop more than just two nipples.

The world could make a huge leap forward if we could just leave hermaphrodites alone, instead of genetically altering them as children "for comformity of appearance", We need genetic anomolies that aren't driving us back into the dark ages.

to twist when men annoy you

So they can cry like a baby when they are getting pierced.

I honestly have no idea about this one.

Sex toys I think! Most men love having their nipples stroked and sucked.

Honest!

Did you know that male rats don't have nipples?

I got a huge kick out of your answer.... I also loved mve17's answer about twisting them... Since everyone seems to know about the biological development thing, I was also thinking that they are for men to play with when they are in the doghouse and their woman isn't letting him near hers.

Glad you found me amusing. I like your Snoopy, BTW.

Thanks!

I put, "to serve as pacifiers for babies when the mother is not available" but I have absolutely no idea. It couldn't be that all fetuses begin as females, or to simplify sex change operations. I don't think its likely that early males could breastfeed, either.

Good question, though, it reminds me of Meet The Parents.

I don't know to look like a person??!?!?

It's pretty simple. Males are basically just modified females. All humans begin life in the womb as female. Anatomically speaking, this is Mother Nature's basic template for the human form. We all develop along the female pathway for much of the first trimester. If no Y chromosome is present, then the fetus will continue to develop as a girl. However, if a Y chromosome *is* present, then the hormone testosterone will be produced and alter the developmental pathway. Ovaries become testes. The labia fuse to form a scrotum. The penis is just an enlarged clitoris threaded by a urethra. However, nipples and the seam on the underside of a male's scrotum (where the labia fused) are left as remainders of the original female state.
