Question:

What is correct about the hormones that stimulate male and female organs to produce male and female sex hormones?

A The hypothalamus stimulates the pituitary gland’s secretion of male and female hormones.
Explaination

In both females and males, the brain’s hypothalamus stimulates the pituitary gland to secrete luteinizing hormone (LH) and follicle-stimulating hormone (FSH). In females, these two hormones stimulate the ovaries to produce estrogen; in males, they stimulate the testes to produce testosterone. Hence, both female and male organs are stimulated by the same hormones, not each by female or male hormones (A). LH and FSH, the hormones that stimulate the male and female sexual organs, are not the same as estrogen and testosterone, which respectively stimulate the male and female organs to produce these sex hormones (B). The pituitary gland does not secrete these (D); it secretes LH and FSH.
