Final answer:
FSH and LH are produced by gonadotropes in the anterior pituitary gland, which are stimulated by GnRH and regulated by a negative feedback mechanism involving sex steroids.
Step-by-step explanation:
The cells in the anterior pituitary that produce follicle-stimulating hormone (FSH) and luteinizing hormone (LH) are known as gonadotropes. In response to gonadotropin-releasing hormone (GnRH) from the hypothalamus and under the influence of a negative feedback loop involving sex steroids like androgens and estrogens, gonadotropes secrete these hormones.
FSH and LH are essential in regulating the gonads, stimulating gamete production and the release of sex hormones. In the context of the question, the correct answer to which cells produce FSH and LH in the anterior pituitary is (b) Gonadotropes.
