male and female reporductive organs

this is a thought i got last night out of the blue (i love thoughts that just pop into my head, but some get me into trouble). well this one was about male and female reporductive organs and how, even though one is inside and one is outside, when compared they look very similar.

what i mean is that the male has a penis and a scrotum and a female has the uterus and her vaginal passage, and if you compare them they look almost the same (except for the obvious differance).

what is your collective thoughts on this?

well i would figure it comes from male and female fetus's not having a specific sex for the beginning of the pregnancy...

We are all female when we are initially formed in the uterus.

When the sex hormones kick in, for males at least, we grow skin that represents the scrotum and the sensitive part of our new organ then becomes the glans of the penis. If you are female, that piece of skin forms the clitoris.

I cannot say for sure that the skin of the "uterus" becomes the shaft of the penis (if you become male) , but it certainly is an intriguing theory.

/me is not a biologist by any stretch of the imagination.

wow Jstride....I didnt know that....I thought it happened upon conception (lol and I've had a baby) I had to look it up because I didnt belive you (no offense) here's some info incase there are others like me.

All embryos are identical in external appearance for the first eight weeks of gestation, and then several factors nudge the infant toward male or female development. In the seventh week, the embryo has both male and female primordial ducts. In the normal female fetus, the millerian duct system then develops into oviducts and a uterus. In the normal male fetus, the wolferian duct system on each side develops into the epididymis and vas deferens. The external genitalia are similarly bipotential until the eighth week (The reproductive organs and genitals associated with "female" or "male" arise from the same initial (fetal) tissue). Thereafter, the urogenital slit disappears and male genitalia form or alternatively, it remains open, and female genitalia form.

If the egg was fertilized with the x chromosome then the female structures continue to mature, the default system.

However if the y chromosome fertilized the egg then a hormonal switch happens,,, two genes are activated and the female structures are completely dissolved and destroyed and the male organs take their place.

wow cool didnt know that. learn something new everyday.

theres a lot on that in the "why do men have nipples thread"

to tease babies with and to chafe when irritated by thick-stranted tshirts (nature's self defense mechanism)

(edited to note this is about the nipples, not the reproductive organs' similarities ... :p )

A fetus' sexual organs start in what we can call a sexually-indifferent stage (up to week 5 or 6). This formation has the ability to develop either into the male or female reproductive organs. Various factors then kick in and then the organs begin to develop - thus they will have anatomical similarity due to the same starting origins.

Damn... Don't do that to me! The thought of having an inverted vagina makes me green in the face, but if it was a normal one, then thats another story.
