Male and female reproduction organs

Sexually, men and women present different organs, but those work almost after the same rules. For example, the female clitoris corresponds to male penis, corpora cavernosa is the homologous of female clitoris, corpus spongiosum- of the labia minora, and scrotum- of the labia majora. The explanation of all those similarities is that, embryologically, all came from the same tissue.

male reproductionThe external sexual organs at men are penis and scrotum. Talking about those, we are implicitly mention about:

  • -glans- a very sensitive gland covered by the prepuce, connected to the penis through the corona
  • -corona and frenum- pieces of flesh that connects the shaft and head of the penis
  • -prepuce (foreskin)- a ply of skin that envelopes the head of the penis
  • -urethra- a tube at the tip of the penis that allow urine and semen abstraction
  • -scrotum- a sack that hang on behind and below penis, having the function to maintain testes at 34 C temperature ( the one that makes producing of sperm most effectively)
  • -smegma- a substance secreted by glands on each side of the frenulum

On the other side, internal sexual organs are testicles- glands that produce sperm and testosterone, that contains seminiferous tubules. Each testicle produces daily approximately 150 million sperm. The mature sperm goes to epididymis, where it stays until ejaculation. The epididymis is connected to seminal vesicles through vas deferens.

In testicles also exist:

  • -seminal vesicles- they produce semen, a fluid that protects the sperm after ejaculation
  • -the prostate gland- prevents urine mixing with the semen
  • -corpa cavernosa- two spongy bodies that cause the erection
  • -corpus spongiosum- traversed by the urethra
  • -ejaculatory ducts- ducts that transports the semen during the ejaculation
  • -Cowper’s glands- secrets a pre-ejaculate fluid before orgasm

female reproductionIn women, the external sexual organ is vulva. Talking about it, we also mean:

  • - mons Veneris- a tissue that covers the pubic bone between the abdomen and labia, protected it from the impact of the intercourse
  • - labia majora- lips of vulva, tissue that wrap around vulva between mons and perineum; it is usually covered with pubic hair and contain oil glands
  • - labia minora- the inner lips of vulva that protects the vagina, urethra and clitoris. It is very sensitive to touch and pressure
  • - clitoris- a small white spongy tissue, extremely sexually sensitive; sexual excitement can extend it
  • - urethra- the passage of the urine
  • - hymen- a very thin membrane at the enter of the vagina, usually the symbol of the virginity
  • - perineum- a short stretch of skin between the bottom of the vulva and anus

The internal sexual organs are vagina, uterus, ovaries and G-spot.

  • -vagina- it is the receptacle for the penis during the intercourse; it is also the canal through which the baby passes. It extends from the vaginal opening to the cervix.
  • - Bartholin’s glands- produce a lubricating fluid to keep moist labia minora during sexual excitement.
  • - G-spot- the most sexually sensitive part of the body
  • - cervix- the opening to the uterus
  • - uterus- the main female internal reproductive organ, lined with strong muscles that help pushing the child out during labor
  • - ovaries- they product estrogen and progesterone and ova. At birth, ovaries contain almost 400 000 ova. Eggs that are not fertilized are eliminated during menstruation.

In life, all those glands and organs changes their dimensions, lengths, and, sometimes, even the functions.
