• Urethra is the tube that carries urine from the bladder to the outside of the body and is also the passageway of the sperms out of the male's body.
• Testicles (testes) are oval-shaped organs that lie in the scrotum.
• Epididymis is a long, coiled tube that rests on the backside of each testicle.
• The testes are responsible for generating sperm and making testosterone the primary male sex hormone.

• Uterus (womb) is a muscular organ shaped like an inverted pear and it houses the developing baby.
• Ovaries are a pair of small glands that produce the female hormones, such as estrogen and progesterone.
• Fallopian tubes (oviducts) are two very fine tubes leading from the ovaries into the uterus.
• Fallopian tube allow passage of the egg from the ovary to the uterus.
