Our internal and external genital organs change due to the influence of hormones in the different stages of life and have different tasks to fulfill. Find out what these tasks are, what role the hormones play in this and what diseases can occur on the genitals.
What matters to the genitals?
We all have external and internal sexual organs which we need for sexual union and reproduction. The reproductive organs produce the semen and ova under the influence of hormones, form sex hormones and produce secretions in order to positively influence the reproduction. In genitals, a distinction is made between an inner and an outer part.
The internal female genitalia include the vagina, uterus, fallopian tubes, ovaries and bartholin glands, the pubis include the pubic mound, labia, clitoris and vaginal entrance.
The internal male reproductive organs include the testes and epididymis, the vas deferens and spermatic cord, and the prostate gland, the seminal vesicles, and the cowper glands. The external sex organs are scrotum and penis.
The sexual organs are the primary sexual characteristics, the secondary features include the changes that develop during puberty, such as beard growth and the pronounced change in the tone of voice in men and the growth of breasts in women. Tertiary sexual characteristics are the differences between female and male physique and body size, as well as the different sex-typical behaviors.
What function do the sexual organs have?
The sexual organs are needed for both sexual union and reproduction. There was a long uncertainty about the exact function of the sexual organs: until the 17th century, on the one hand, there was the theory that an embryo develops from a female egg and is only stimulated by the male sperm, and the other thesis is that the embryo originates from the Seed thread of the man develops and the female egg represents only a food depot. It was not until the 19th century that chromosomes were discovered to transmit the genetic information and the exact processes of fertilization.
Function of the sex organs in the woman
The ovaries are already present in an unfinished form in the ovaries before birth. As of puberty, some cells mature each month via intermediate stages to at least one fertile egg cell, which is then transported via the fallopian tubes into the uterus, where it is implanted in the event of fertilization.
The uterus consists of strong musculature, is usually plum-sized and lined with a mucous membrane layer inside. It surrounds the growing child during a pregnancy, makes the mother cake and can reach pumpkin size.
The uterus protrudes into the vagina with its neck - this is the connection between inner and outer sex organs. Their glands produce secretions that make it difficult for germs to spread and contribute to the sexual activity of the sexual organs during intercourse.
The external female genitalia, with its erogenous zones, clitoris and glands, plays an important role in sexual stimulation, which is aimed at sexual union.
Function of the genital organs in men
In the testes and epididymis deposited on them take place the development, maturation and storage of sperm cells (sperm). During ejaculation, sperm are thrown into the urethra via the muscular vas deferens.
Shortly before the discharge of the sperm duct into the urethra, a secretion from the prostate (prostate gland), seminal vesicles and cowper glands is added to the sperm cells, which improves sperm motility and offers them some protection against vaginal secretions. This semen, the semen, is released during ejaculation and can contain up to 500 million sperm.
In sexual arousal, the erectile tissue of the penis fill with blood, so that an erection occurs. Most ejaculation occurs as a culmination of sexual arousal, while the semen is transported by involuntary contractions of the muscles of the vas deferens, urethra and penis from the male body.
