With reference to the human body consider the following statements: 1. The production of somatotropin goes up when a person exercises 2. Men’s testes produce progesterone 3. Women’s adrenal glands secrete testosterone 4. Stress causes the adrenals to release very less amount of cortisol than usual Which of these statements are correct?

Result
Your answer: —  ·  Correct: B
Explanation

Statement 1 is correct: growth hormone (somatotropin) is released in pulses and levels rise after exercise, trauma and sleep, so exercise increases GH secretion [1]. Statement 2 is incorrect: testes primarily secrete testosterone (and not progesterone) and are the main source of androgens in males [2]. Statement 3 is correct: in women the adrenal cortex produces androgenic precursors (e.g., DHEA, androstenedione) that serve as sources for peripheral testosterone; adrenal glands thus contribute to female testosterone levels [3]. Statement 4 is incorrect: stress provokes increased cortisol release from the adrenals (not markedly reduced release). Therefore only statements 1 and 3 are correct.
