Sukupuolielimissä

Sukupuolielimet, also known as genitalia, are the external and internal organs that are part of the reproductive system. They play a crucial role in sexual reproduction and the production of sex hormones. The anatomy and function of these organs differ between biological sexes, though variations exist.

In individuals typically assigned male at birth, the external genitalia include the penis and scrotum. The penis is responsible for delivering sperm into the female reproductive tract during intercourse and also for urination. The scrotum is a sac of skin that holds the testes, where sperm and testosterone are produced. Internal male reproductive organs include the testes, epididymis, vas deferens, seminal vesicles, prostate gland, and bulbourethral glands, which all contribute to sperm maturation, storage, and transport, as well as the production of seminal fluid.

In individuals typically assigned female at birth, the external genitalia, collectively known as the vulva, include the labia majora, labia minora, clitoris, and vaginal opening. The clitoris is a highly sensitive organ primarily for sexual pleasure. The vagina is a muscular canal that connects the vulva to the internal reproductive organs and serves as the birth canal and the pathway for menstrual flow. Internal female reproductive organs include the ovaries, fallopian tubes, uterus, and vagina. The ovaries produce eggs and hormones like estrogen and progesterone. The fallopian tubes transport eggs from the ovaries to the uterus, where fertilization can occur. The uterus is where a fertilized egg implants and a fetus develops.

The development of reproductive organs is influenced by genetics and hormones, particularly during fetal development and puberty. Beyond reproduction, genitalia are also a source of sexual sensation and are integral to sexual activity and intimacy.
