Internal genitalia

Internal genitalia refers to the sex organs that are located inside the body. These organs play a crucial role in sexual reproduction and are typically differentiated between male and female organisms.

Male Internal Genitalia

The male internal genitalia primarily consist of the testes, epididymis, vas deferens, seminal vesicles, and prostate gland.

• The testes are responsible for the production of sperm and testosterone, the primary male sex hormone.
• The epididymis is a long, coiled tube that stores sperm and transports it from the testes.
• The vas deferens is a muscular tube that transports mature sperm to the urethra.
• The seminal vesicles and prostate gland produce seminal fluid that nourishes and protects the sperm.

Female Internal Genitalia

The female internal genitalia primarily consist of the ovaries, fallopian tubes, uterus, and vagina.

• The ovaries are responsible for the production of eggs and the female sex hormones estrogen and progesterone.
• The fallopian tubes transport the eggs from the ovaries to the uterus. Fertilization of the egg by a sperm typically occurs in the fallopian tubes.
• The uterus is a muscular organ where the fertilized egg implants and grows during pregnancy.
• The vagina is a canal that serves as the birth canal during childbirth and also as the conduit for menstrual flow from the uterus.
