Urogenital system anatomy in 3D:
male

The male urinary and reproductive organs within the pelvis, with their vessels and nerves.

The kidneys lie in the retroperitoneum, and the ureters descend to the bladder; the male urethra passes through the prostate and the penis. The testes produce sperm and testosterone, and the sperm travel through the epididymis, ductus deferens and ejaculatory ducts, with secretions added by the seminal vesicles and prostate.
