Final answer:
Testosterone is produced by Leydig cells, also known as interstitial cells, which are located between the seminiferous tubules in the testes, not within the tubules themselves.
Step-by-step explanation:
The hormonal product of the testis, testosterone, is an androgen, which is a type of steroid hormone. This hormone is produced by Leydig cells, also known as interstitial cells. Leydig cells are found between the seminiferous tubules within the testes. The seminiferous tubules, on the other hand, are the site where spermatogenesis occurs, which is the process of sperm production. Leydig cells begin to secrete testosterone by the seventh week of male embryonic development, reaching peak concentrations during the second trimester, which leads to the anatomical differentiation of the male sexual organs.
Testosterone is critical for initiating and maintaining sperm production and is also vital for developing secondary sex characteristics during puberty.Testosterone is produced by Leydig cells, also known as interstitial cells, which are located between the seminiferous tubules in the testes, not within the tubules themselves.
