Verified step by step guidance1
Step 1: Begin by identifying the function of testosterone in the male reproductive system. Testosterone is the primary male sex hormone responsible for the development of secondary sexual characteristics and the regulation of spermatogenesis.
Step 2: Understand the anatomy of the testes. The testes contain two main types of cells involved in hormone production and sperm development: Leydig cells and Sertoli cells.
Step 3: Learn the specific roles of Leydig cells and Sertoli cells. Leydig cells, located in the interstitial space of the testes, are responsible for secreting testosterone. Sertoli cells, found within the seminiferous tubules, support and nourish developing sperm cells but do not produce testosterone.
Step 4: Eliminate the incorrect options. Beta cells and Alpha cells are not found in the testes; they are associated with the pancreas and are involved in insulin and glucagon secretion, respectively.
Step 5: Conclude that Leydig cells are the correct answer, as they are the specific cells in the testes responsible for secreting testosterone.
