Which of the following hormones triggers the production of testosterone?
A
Thyroid-stimulating hormone (TSH)
B
Prolactin
C
Luteinizing hormone (LH)
D
Follicle-stimulating hormone (FSH)
Verified step by step guidance1
Understand the role of each hormone listed in the options. Thyroid-stimulating hormone (TSH) primarily stimulates the thyroid gland to produce thyroid hormones, not testosterone.
Recognize that prolactin is mainly involved in milk production and has no direct role in testosterone production.
Identify the function of follicle-stimulating hormone (FSH). FSH is involved in the regulation of reproductive processes, but it primarily stimulates the growth of ovarian follicles in females and spermatogenesis in males, not directly triggering testosterone production.
Learn about luteinizing hormone (LH). LH is crucial in the reproductive system as it stimulates the Leydig cells in the testes to produce testosterone in males.
Conclude that luteinizing hormone (LH) is the hormone responsible for triggering the production of testosterone, as it directly influences the Leydig cells in the testes.
