AB The  male  reproductive  system  consists  of  the  testes,  genital  ducts,  accessory  glands,  and  penis  (Figure  21–1).  Testes  produce  sperm  but  also  contain  endocrine  cells  secreting  hormones  such  as  testosterone,  which  drives  male  reproductive  physiology.  Testosterone  is  important  for  spermatogenesis,  sexual  differentiation  during  embryonic  and  fetal  development,  and  control  of  gonadotropin  secretion  in  the  pituitary.  A  metabolite  of  testosterone,  dihydrotestosterone,  also  begins  to  act  on  many  tissues  during  puberty  (eg,  male  accessory  glands  and  hair  follicles).
