$\begin{array}{cc}\text{A. FSH}& \text{1. Stimulates Leydig cells of}\\ & \text{testes}\\ \text{B. Luteinizing hormone}& \text{2. Responsible for the release of FSH, LH}\\ \text{C. Gonadotropin releasing hormone}& \text{3. Stimulates spermatogenesis}\end{array}$

• A. A-1, B-2, C-3
• B. A-2, B-3, C-1
• C. A-2, B-1, C-3
• D. A-3, B-1, C-2

Answer 1

The correct option is D A-3, B-1, C-2

Gonadotropin releasing hormone (GnRH) is produced by hypothalamus and it stimulates the anterior pituitary gland. It causes the secretion of LH (luteinizing hormone) and FSH (follicle stimulating hormone) from the anterior pituitary. FSH and LH are called gonadotropins as they stimulate the testes (gonads). In males, LH stimulates the interstitial cells (Leydig cells) of the testes to produce testosterone that is responsible for development of male sexual characters and the FSH stimulates spermatogenesis.
