Testosterone is primarily produced by the testes, specifically by Leydig cells within them ([1], [2], [3], [4], [5], [6], [7], [8]). The testes regulate testosterone output in response to hormonal signals from the brain and pituitary ([9], [10]). This production drives male reproductive development, puberty changes, and spermatogenesis ([11], [12], [13], [14]).

claimTestosterone stimulates the development of the Wolffian ducts in the male fetus, which differentiate into the testes, epididymis, vas deferens, and seminal vesicles.
claimLeydig cells in the testes produce testosterone, which is the primary driver of male reproductive development.
claimLH stimulates Leydig cells in the interstitium of the testes to produce testosterone from cholesterol.
claimWhile the majority of testosterone production in men occurs in the Leydig cells of the testes, the adrenal cortex also contributes to androgen production.
claimAdrenocorticotropic hormone (ACTH) stimulates the enzyme desmolase to convert cholesterol into pregnenolone in the adrenal glands, a process analogous to testosterone synthesis in the testes.
claimTestosterone is the major male androgen and is produced by Leydig cells located in the testes.
claimFSH and testosterone stimulate Sertoli cells, located in the periphery of the seminiferous tubules of the testes, to release androgen-binding protein (ABP), which provides testosterone to germ cells during spermatogenesis.
Reproductive Hormones endocrine.org Endocrine Society 5 facts
claimThe brain and the pituitary gland, located at the base of the brain, regulate the production of testosterone by the testes.
claimIn a fetus with XY chromosomes, the testes produce Anti-Müllerian Hormone (AMH), which causes the Müllerian ducts to disappear, and testosterone, which promotes the development of the male reproductive system.
claimThe testes are the organs responsible for producing testosterone in men.
claimDuring puberty, testosterone facilitates physical changes in boys, including growth of the penis and testes, development of facial, pubic, and body hair, deepening of the voice, increased muscle and bone strength, and height growth.
claimOvaries in females and testes in males are the primary production sites for the reproductive hormones estrogen, testosterone, and progesterone.
