Verified step by step guidance

Understand the roles of Leydig and Sertoli cells in the male reproductive system. Leydig cells are primarily responsible for producing testosterone, a key hormone in male development.

Recognize the location of Leydig cells. They are found in the interstitial tissue surrounding the seminiferous tubules, not within the tubules themselves.

Identify the function of Sertoli cells. These cells are located within the seminiferous tubules and play a crucial role in supporting and nourishing developing sperm cells.

Clarify the hormonal functions: Sertoli cells do not produce testosterone; instead, they assist in the process of spermatogenesis and secrete factors that regulate the function of Leydig cells.

Understand the role of luteinizing hormone (LH): LH stimulates Leydig cells to produce testosterone, but Sertoli cells do not secrete LH.
