Question

Quizplus · Accepted Answer

The male reproductive functions such as spermatogenesis and testosterone production are primarily controlled by hormones from the hypothalamus and the anterior pituitary gland. The hypothalamus produces gonadotropin-releasing hormone (GnRH) which stimulates the anterior pituitary gland to release luteinizing hormone (LH) and follicle-stimulating hormone (FSH) into the bloodstream. LH stimulates the Leydig cells in the testes to produce testosterone while FSH stimulates the Sertoli cells which aid in spermatogenesis. Therefore, the correct answer is option D - anterior pituitary gland and testes.
