How do androgens support sperm production and the male reproductive tract?

Androgens, which are steroid hormones secreted by the testes, are essential for the maintenance of spermatogenesis and the functional integrity of the male reproductive tract.1

Role in Sperm Production

Spermatogenesis is the process by which sperm cells are produced within the seminiferous tubules of the testes. This process is stimulated by testosterone—the principal androgen—acting locally within the testes, in conjunction with follicle-stimulating hormone produced by the pituitary gland. Within the reproductive tissues, testosterone is often converted into 5α-dihydrotestosterone, a more potent androgen that further supports these processes.21

Role in the Reproductive Tract

Beyond sperm production, androgens are responsible for maintaining the tissues of the male reproductive tract in a fully functional state. They play a critical role in the development of male secondary sex characteristics and the overall regulation of the male reproductive system. By maintaining these tissues, androgens ensure the environment necessary for the maturation, storage, and eventual transport of spermatozoa through the epididymis and spermatic ducts.123
