What determines the formation of a penis, penis shaft and scrotum instead of clitoris, labia minor and major?

the presence (or absence) of a "y" sex chromosome.  If the "y" chromosome is present, male genetals develop.  Otherwise (two "x" chromosomes), the genetals will develop as female.  The sperm (male sex cell) has the "x" and the "y" possibilities.  (each only gets one).  The female sex cell (egg) only has the possibility of an "x" chromosome for the sex.  There is a possibility that an egg can form incorrectly and have two "x" chromosomes.  If the sperm for this type of egg is a "y" sperm, it will still develop as male.

Basically the same thing, only the "penis" is a clitoris, gets hard and swells, lubricants are produced and the vagina opens.

That is such a brilliant question!\n\nFor a man:\n1 an*l sphincter\n1 sphincter on the penis\n2 'earholes'\n2 nostrils\n1 mouth\n=7 in total\n\nWoah there!! It's not the same for women! They have 8: the vagina and urethra are separate holes (unless it's true that babies grow in the bladder and not the uterus...)\n\nThere are millions if you count sweat glands and the holes where hair follicles grow...\n\n[Edit: I wouldn't go so far as to say there were an infinite number!]\n[Edit: Hmmm.. what ARE the 9 holes, Foolsbane?]

Clitoris is the most sensitive area of a female it is part of female genitals where the outer labia meet .It is like a male penis but not developed .It is sensitive to touch and when a female is aroused it becomes a bit big.\nNo two females clitoris will be alike .Check the website below for different types of clitoris

There are cases of two penises, or a penis and a vagina.  But I have never heard nor seen of two vaginas, or 2 penises and a vagina.  Could be a case of misidentification of organs.

According to sexologist by bending the knees or holding their legs up, they change the relation to the pelvis(the female symphysis)and the inserted penis. The clitoris is not only seized between the pelvis of the man and the woman for maximum stimulation. This position allows for full penetration into the woman. All the way to the back of the vaginal cavity to a point where the cervix is pushed aside. Other than the woman on top position this is said to be the best position for those trying to conceive and for women to achieve orgasm.

Frenulum Linguae is the right answer. To be accurate, you \nmust add Linguae.\nThere are many Frenulum tissues in the body, eg frenulum clitoridis (for clitoris), frenulum labiorum pudendi (for labia minora), frenulum preputii penis (for penis prepuce...lower side), frenulum labii superioris and frenulum labii inferioris for upper and lower lips respectively.

One unusual feature of the hyena is that females have an enlarged clitoris called a Pseudo-penis. Female hyenas give birth, copulate, and urinate through their protruding genitalia, which stretches to allow the male penis to enter for copulation, and it also stretches during birth. The anatomical position of the genitalia gives females total sexual control over who is allowed to mate with them. Researchers originally thought that one of the things that causes this characteristic of the genitals is androgens that are expressed to the fetus very early on in its development. However, it was discovered that when the androgens are held back from the fetus, the development of the female genitalia was not altered.

It is NOT where your pee comes out...that is your urethra.  The clitoris (sometimes called clit) is the female version of a penis.  It has many nerves and when stimulated can cause an orgasm.  A woman has a clitoris, urethra (urine), vagina(periods, sex, babies) and rectum/anus (feces/bowel movement).

The basic mammalian body plan is female - and both genders go through similar early embryo development (including the development of nipples). Later in embryonic growth, genes on the X and Y chromosomes turn-on. These produce the various sex hormones that form the genitals and, in females, mammary glands.

little people have penises that are proportionate to their size, just like "normal" sized men. I have known a little person who has had a penis that was larger than "normal"

because while you are developing intruterine, you r sex could go either way, until the correct signal is interpreted that now tells you whether you will be male or female.\nthat is when the body parts start to differentiate....\npenis becomes clitoris, testicles do not descend and become ovaries, the scrotum stays split and becomes the labias...nipples will stay, they will not just disappear

The penis of males is not prehensile (prehensile means able to grasp), but it's long and extremely mobile thanks to the muscles attaching it to the reduced pelvic bones. Normally it's retracted inside the body cavity, but duriig courtship the penis is evaginated and inserted in the female reproductive tract. This is accomplished with both animals more or less alongside each other (which is not so easy in water).

The clitoris is the key to sexual pleasure for the majority of women. Only women are endowed with an organ that has no other purpose than to give them intense pleasure. A good understanding of the clitoris is essential to the sexual health and emotional happiness of women. The clitoris is often overlooked and neglected. While there are billions of women, it is extremely hard to locate factual information about how the clitoris functions and contributes to the pleasure of women. The size of the body of the clitoris varies from zero to about two inches. The size of the average clitoral body is about three quarters of an inch, making the average body and glans an inch in length. This is the portion of the clitoris you will be able to touch and feel with your fingers, beneath the prepuce. The crus are each about three inches in length making the average clitoris four inches in length; a lot bigger than most people realize.
