Explanation
1. Statement 1 is correct. Exercise stimulates the pituitary gland to release Growth Hormone (somatotropin). The production (release) of somatotropin goes up during and after physical exercise.
2. Statement 2 is incorrect. Men's testes primarily produce testosterone (an androgen). While they produce trace amounts of progesterone, it is not their main product; progesterone is primarily a female sex hormone produced by the ovaries and placenta.
3. Statement 3 is correct. While testosterone is the primary male sex hormone, women's adrenal glands (and ovaries) also secrete small amounts of androgens, including testosterone, which play roles in female physiology.
4. Statement 4 is incorrect. Stress triggers the 'fight-or-flight' response, causing the adrenals to release significantly *more* cortisol (a primary stress hormone), not less.
5. The question asks for correct statements, but the options (A, B, C, D) seem to be matching codes (like A-2, B-4...), which doesn't fit the question format 'Which of these statements are correct?'. Assuming the options refer to which statements are correct, and given the answer 'd', let's re-examine. If answer 'd' implies Statements '1 and 3' are correct (based on common option formats, though not shown here), this aligns with our analysis above. However, the options provided (A-2, B-4, C-3, D-1 etc.) suggest a matching format was intended but the question text is a statement verification type. Assuming the provided answer 'd' corresponds to a hypothetical option like '(D) 1 and 3 only' which is missing: statements 1 and 3 are correct. *Analysis based on reinterpreting the likely intended format corresponding to answer 'd'.*
