Are there any similarities between male and female reproductive organs?

Question

Is it true that male has a female reproductive organ? Or vice versa?

I mean the physical similarity not the functional similarity. Please help me.

Answer 1

we are more similar than most realize, esp if we look at the embryological origins of these m-f tissues.

Internally both genders started out with NON-differentiated gonads. If the XX is present, this turns into an ovary in embryo USUALLY. If XY is present, then it turns into testes USUALLY.

In the embryo there are also BOTH sets of tubes: Wollfian ducts and Mullerian ducts. Wollfian ducts will become vas deferens. The Mullerian duct will become the oviduct-Fallopian tubes. Pseudohermaphrodites might not differentiate thoroughly.

Externally we all started out as an anatomical female. Essentially a guy is a closed up female. During embryo-fetal development the genitals of the baby are very confusing if you don't know what you are looking at. Essentially, the penis that grows is an enlarged clitoris. It has 3 erectile tissues in it, where as the clitoris has 2 erectile tissues. (clitoris does not have the urethra growing in it, so she does not urinate with a clitoris) Many people call the clitoris a small penis, but embryologically speaking it is the other way around. Both genders have labia in utero....the labia stay and persist in the female, but if it is an XY, the labia are supposed to close up. The seam seen on the underside of the scrotum (separating the scrotum into rt-lt halves-compartments to hold each testicle) and the underside of the penis (kinda looks like a scar, but it is NOT a circumcision scar, it is the seam where he closed up when his genitals were more female.

One of the most common birth defects found in the penis is hypospadius, where the underside of the penis has not closed up all the way and so the urine comes out the underside of the head of the penis instead of the tip of the penis where the normal urethral opening is, thus the penis is not completely masculinized and closed up. There is a rarer deformity called epispadius, but the urine hole is on the top of the head of the penis.

There are both true hermaphrodites and at least three kinds of pseudohermaphrodites in humans. True hermaphrodites have both ovary and testis. Pseudo have either or, but the other organs are all mix-match male and female combinations internally and externally.

During embryo development there are critical hormonal changes that help to masculinize the brain of males. If baby is an XX then the masculinizing hormones are not released and the baby's brain stays feminized. Mothers who take masculinizing hormones during pregnancy can masculinize their daughter's brains. They might also turn a normal genetic female into a anatomical male. (Happins in animals too, can get a whole litter to be males if masc hormones given at critical time of embryo dev.)

Also females transexuals who take testosterone as adults will go thru a male puberty and be very transformed a lot within 6 months. They will grow a lot more hair (beards, body, etc) they will grow a bigger larynx, muscles will get leaner-muscular, voice will deepen, their clitoris will grow to be about the size of a thumb and their sexual aggression with be peaked. Their family will not recognize them in 6 months.

Thus, males and females are a lot a like. It is easy to make a male to female transexual surgically because you are taking away the male structures that were ADDED at embryo development. When you make a male from a female transexual, stuff has to be ADDED to make the female.

Thus everyone starts out with the feminized brain, feminized genitalia, and BOTH sets of m-f tubes internally. We have structural homologies of all our organs (in the opposite sex) If all goes well, however, the genetic sex and the internal-external m-f traits all match, PLUS the sexual-gender identity will match the chromosomes and the genitals-gametes-gonads.

Answer 3

It is true that the testicles are similar in shape to ovaries, but that is where those similarities end. Males do NOT start as females. All humans start out the same, asexual. When hormones are introduced during development, the sexual organs form. If a female has too high of testosterone during development, they will be come a hermaphrodite and have what looks like both organs and same goes if males.

Answer 4

well I guess they produce gametes (sperm and eggs) as a result of meiosis and the testes and ovaries produce hormomes that are needed for secondary male and female characterisitics eg penis/scrotum growth, breasts, hair etc I guess that they each have a "gland" the ovary and testicle which pretty much runs the show and pciks up signals from the brain. Diffs I guess is that females are almost entirely internal while male is external the hormones produced are different (well ok males produce some oestrogen and females produce testosterone but in much smaller amounts) and females have more hormones involved eg progesterone, LSH, and a follicle releasing one.. females have a limited reproductive span (ending at menopause) while males have a longer one..ending in death! females have a cycle (menstrual cycle) while males have none, just "urges" I guess. Also while meiosis produces 4 cells, in females only 1 goes on to be an egg, while in males all 4 will become sperm and hence the "millions" produced while female will only produce around 400 and these began forming while the female was in the uterus!!!

Answer 5

Beyond similar-- they actually begin life as the same organ-- structurally anyway. That's why it's so difficult to tell the sex of a very young fetus-- they all have a phallus which becomes a penis in males and a clitoris in females. The gonads are all internal at that time. They become ovaries in females and descend and become testicles in males.

Answer 6

Sort of... we all start out as females, but at a certain point in male fetal development the genes kick in that 'morph' the forming genitalia into a penis and testicles.

Answer 7

They are both most sensitive at the tip/bottom. The vagina is most sensitive about 1 inch inside, and the man is most sensitive at the head. There's something like 20% of the whole body's nerves just in those couple square inches of skin (i forget the exact number). All the blood rushes there when aroused... And both contribute to pregnancy...

Only similarities I can really think of.

Answer 8

at one point (in the womb), males had the female reproductive organ until it was -BAM!- shot up with some testosterone and the peepee developed



something like that

Answer 9

Ovaries are like internal nuts

Answer 10

They share a common initial state in embryos.
