TY - CHAP M1 - Book, Section TI - The Male Reproductive System A1 - Mescher, Anthony L. PY - 2018 T2 - Junqueira’s Basic Histology: Text and Atlas, 15e 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).
