Human reproductive system

The urethra (: urethras or urethrae) is the tube that transports urine from the bladder to the urethral meatus of the penis or vulva in placental mammals. In males, it also transports semen through the penis during ejaculation.

A gonad, sex gland, or reproductive gland is a mixed gland and sex organ that produces the gametes and sex hormones of an organism. Female reproductive cells are egg cells, and male reproductive cells are sperm. The male gonad, the testicle, produces sperm in the form of spermatozoa. The female gonad, the ovary, produces egg cells. Both of these gametes are haploid cells. Some hermaphroditic animals (and some humanssee Ovotesticular syndrome) have a type of gonad called an ovotestis.
