BIOXI22: CHEMICAL COORDINATION AND INTEGRATION

341071 Growth of facial and axillary hair in males is a function of

1 Adrenal androgens

2 Progesterone

3 Testosterone

4 1 and 3

BIOXI22: CHEMICAL COORDINATION AND INTEGRATION

341072 Increased secretion of which hormone starts the process of sperm formation at the time of puberty?

1 GH

2 TSH

3 PRL

4 GnRH

Explanation:

Gonadotropin-releasing hormone $(GnRH)$ is released from the anterior pituitary. GnRH activity is very low during childhood, and is activated at puberty or adolescence. At the puberty increased secretion of GnRH start the process of sperm formation.
