erotinjärjestelmä

The erotinjärjestelmä, also known as the genital system or reproductive system, refers to the organs responsible for sexual reproduction in humans and other animals. It encompasses both the external and internal structures that facilitate the production of gametes (sperm and eggs) and their union to create a new organism.

In males, the erotinjärjestelmä includes the testes, which produce sperm and male hormones, the epididymis and vas deferens for sperm transport, the seminal vesicles and prostate gland which produce seminal fluid, and the penis for copulation. The primary function is the production and delivery of sperm.

In females, the erotinjärjestelmä consists of the ovaries, which produce eggs and female hormones, the fallopian tubes for egg transport, the uterus where a fertilized egg implants and develops, the cervix, and the vagina which serves as the birth canal and receives sperm. The primary functions include the production of eggs, fertilization, gestation, and childbirth.

The development and function of the erotinjärjestelmä are regulated by hormones, primarily sex hormones like testosterone, estrogen, and progesterone. These hormones are crucial for sexual maturation during puberty and for maintaining reproductive capabilities throughout adulthood. The erotinjärjestelmä plays a vital role in the continuation of species.
