Which organs produce sperm and male sex hormones?

• A. Testes
• B. Ovaries
• C. Thymus
• D. Adrenal glands

Answer: (A)

Sperm production and male sex hormone secretion occur in the testes. Within the testes, the seminiferous tubules carry out spermatogenesis to produce sperm, while the nearby interstitial or Leydig cells produce testosterone in response to LH from the pituitary. Testosterone supports both the development of sperm and male secondary sexual characteristics, linking the production of gametes with hormone signaling. Ovaries, by contrast, produce eggs and female hormones (estrogen and progesterone). The thymus is involved in immune cell maturation, and adrenal glands release various hormones, including some androgens, but they are not the primary site for making sperm.
