Function: varies over the lifespan, (cid:271)ut for adults it"s to produce sperm and testosterone; males have some estrogen too. *seven up: seminiferous tubules to epididymis, vas deferens, ejaculatory duct, n/a, urethra, penis; order of sperm through the testes. Site of hormone and sperm production, so the most important reproductive system in the male. Located inside the scrotum (found externally in humans) Encased within a fibrous capsule for protection; within the capsule there are lots of tubes (seminiferous tubules) Sperm moves from the seminiferous tubules to the epididymis and then out the body via the vas deferens. Leydig cells make and release testosterone to get to sertoli cells, muscle tissue and to reproductive structures (i. e. the prostate: endocrine signalling; paracrine signalling.
