Result
Your answer: —  ·  Correct: A
Explanation

The correct statements are 1, 2, and 3.

  • Statement 1 is correct: Somatotropin (Growth Hormone) production increases during physical exercise as the body requires it for muscle growth and fat metabolism.
  • Statement 2 is correct: In the male reproductive system, progesterone is synthesized in the Leydig cells of the testes. It serves as an intermediate in testosterone biosynthesis and is also secreted into the blood.
  • Statement 3 is correct: In females, the adrenal glands produce about 25% of the body's testosterone.
  • Statement 4 is incorrect: Under stress, the adrenal glands release increased amounts of cortisol (the body's primary stress hormone) via the HPA axis; levels do not go down.
