THE PITUITARY HORMONE THAT STIMULATES SPERMATOGENESIS: Answer a. adrenaline b. progesterone c. estrogens d. follicle-stimulated e. luteinizing

## Step 1<br />The question is asking for the pituitary hormone that stimulates spermatogenesis. Spermatogenesis is the process of sperm cell production in the testes.<br /><br />## Step 2<br />The pituitary gland produces several hormones, including Follicle Stimulating Hormone (FSH) and Luteinizing Hormone (LH). Both of these hormones play a crucial role in the reproductive system.<br /><br />## Step 3<br />FSH is responsible for stimulating the growth of ovarian follicles in females and spermatogenesis in males. LH, on the other hand, triggers ovulation in females and stimulates the production of testosterone in males.<br /><br />## Step 4<br />Given the options, the hormone that directly stimulates spermatogenesis is FSH.
