D)decreased secretion of thyroid stimulating hormone.

Question

Quizplus · Accepted Answer

Increased circulating concentrations of testosterone would stimulate negative feedback on the hypothalamic-pituitary-gonadal axis, leading to decreased secretion of luteinizing hormone. Luteinizing hormone is responsible for stimulating the production of testosterone in the testes, so decreased LH secretion would help to prevent excessive testosterone production. However, testosterone levels would not affect the secretion of growth hormone, adrenocorticotropin, or thyroid stimulating hormone.
