Step 1: Understanding the Concept:
Puberty is the stage of development when adolescents undergo physical and hormonal changes leading to sexual maturity. Hormones play a vital role in regulating these changes.
Thyroxine: Controls metabolism and growth but not puberty.
Estrogen: Female hormone responsible for female reproductive development.
Testosterone: Male hormone responsible for secondary sexual characteristics during puberty.
Step 2: Detailed Explanation:
Among these, testosterone is the main hormone responsible for controlling the symptoms of puberty in male adolescents, such as deepening of voice, facial hair growth, and muscle development. Estrogen controls puberty in females, but since the question asks generally, testosterone is considered the key hormone.
Step 3: Final Answer:
The hormone that controls the symptoms of puberty in adolescents is Testosterone.
