Testis anatomy. Cutaway artwork showing the internal anatomy of the human testis (testicle), part of the male reproductive system. The testes are where the male sex cells (spermatozoa) are produced. This process, called spermatogenesis, occurs in the seminiferous tubules, seen coiled in the main body of the testicle. An expanded view of the inside of a seminiferous tubule and the production of spermatozoa is at lower right (see also C021/7891). The coiled structure on top of and adjacent to the testicle is the epididymis. This carries the sperm to the spermatic duct (vas deferens) that ascends to top left into the abdomen.
