Sex organs

Some people are under the false impression that the sexual organs are the only organs involved. However, the human sexual response is not restricted to a few particular organs, but is a response of the entire body. Thus the mouth and the skin, for example, are also “sexual” organs because they transmit and receive sexual stimulation.

Female genital organs

They consist of two parts:

1) the internal genitalia, located in the pelvis: the ovaries, the fallopian tubes, the uterus and the vagina, and

2) the external genitalia (the female vulva or pudendal), including the labia majora, labia minora, clitoris, and hymen.

Ovaries

These are two organs where female cells (the ovum) develop and mature and female sex hormones are made. They are located in the minor pelvis on both sides of the uterus, they have an oval shape with a weight around 5 to 6 g.

Two layers of substances are distinguished in the ovary: medullary and cortical substance . In the medulla we see connective tissue through which the vessels and nerves enter. In the cortical we find the ovarian follicles that develop together with the ovule and with their maturation they pass to the fallopian tube (or uterine tube), where the follicle breaks and the ovule leaves in what is called ovulation . If it is not fertilized mature, menstruation occurs.

Fallopian tube

Peer organ, which enables propulsion from the ovary to the uterus. Its walls are composed of three layers, mucosa, muscle, and a serous, the muscle is composed of smooth muscle tissue that is responsible for the propulsion of the egg.

Uterus

Muscular organ, intended for maturation, containment and expression of the fetus. It is located in the minor pelvis between the bladder and the rectum. It has a neck (cervix) that goes into the vagina. The uterus is movable: when the bladder is full it moves back, and when the rectum is full it moves forward.

Vagina

It consists of several parts.

  • internal part or endometrium: when the egg is not fertilized, it detaches and its blood vessels rupture and menstruation occurs.
  • middle part or myometrium: composed of smooth muscle tissue that facilitates the exit of the fetus.
  • external part or perimeter: it covers and protects the uterus.
  • greater pudency lips.
  • minor pudency lips.

Clitoris

It has two cavernous bodies that facilitate its arousal and a large number of nerve endings.

Male genital organs

Male genital apparatus.

The male genitalia comprise the testes with their robes, the vas deferens with the seminal vesicles, the prostate, the urethral bulb glands, and the penis, made up of the corpora cavernosa.

Testicles

They are contained in the scrotum. In them, the production of sperm occurs and the sex hormones are produced. It presents the epididymis, located in its posterior part, which continues with the vas deferens with a length of 40 to 50 centimeters, which allows the passage of semen. In the inguinal canal it forms the spermatic phonicle where nerves, blood vessels and lymphatics enter.

Seminal vesicle

It is an even organ of 4 to 5 centimeters in length located at the bottom of the urinary bladder and the rectum, they are the reservoir of semen. Then we find the ejaculatory duct that allows the passage of semen into the urethra .

Prostate

It is located attached to the bottom of the bladder, secreting a substance that enters the composition of the spermatic fluid.

Bulbourethral gland

It is the gland that is responsible for secreting the lubricating liquid before ejaculation, which also prevents the exit of waste along with semen, such as urine remains, etc.

Scrotum

It is a cutaneous pouch that serves as a deposit for the testicles and their appendages.

Penis

It is composed of head or glans, body and root, in the glans the external hole of the urethra is located. This presents a large number of cavities or small cells that during excitation fill with blood and cause their erection.
