Verified step by step guidance

Understand the role of interstitial cells (Leydig cells) in the male reproductive system. These cells are located in the testes and are responsible for producing testosterone, a key hormone in male physiology.

Review the function of Luteinizing Hormone (LH). LH is secreted by the anterior pituitary gland and plays a critical role in stimulating the interstitial cells to produce testosterone.

Compare the roles of the other hormones listed: Follicle-stimulating hormone (FSH) primarily stimulates spermatogenesis in the testes, Adrenocorticotropic hormone (ACTH) regulates cortisol production in the adrenal glands, and Prolactin is involved in milk production in females.

Identify that LH specifically targets the interstitial cells in the testes to promote testosterone secretion, making it the correct answer in this context.

Conclude that understanding the specific functions of each hormone is essential for determining their roles in physiological processes, such as testosterone production.
