If testosterone secretion from the testes is low, which effect is more likely in an adolescent boy?
Answer and explanation
Correct answer: Development of secondary sexual characteristics may be slower
Testosterone is an androgen secreted mainly by the testes. During adolescence it supports male secondary sexual characteristics, including facial and body hair, deepening of the voice and development of muscles and reproductive tissues. If its secretion is low, these changes may be delayed or slower, so option A is correct. Blood glucose is chiefly regulated by insulin and glucagon, while C and D concern plants.
