Sperm production. Coloured scanning electron micrograph (SEM) of healthy spermatozoa (sperm,pink) passing along a tube in the rete testis of a testis. The testes are the male organs that produce sperm,the male gametes (sex cells). The rete testis is a network of tiny tubes that links the seminiferous tubules,where the sperm are formed,to the efferent ducts (vasa efferentia). These ducts carry the sperm to the epididymis,a structure behind the testis where the sperm mature and are stored ready for ejaculation. Magnification unknown | |
