Which hormone is the primary male sex hormone?

• A. Estrogen
• B. Testosterone
• C. Glucagon
• D. Insulin

Answer: (B)

Testosterone is the primary male sex hormone. It is produced mainly in the testes and drives the development and maintenance of male reproductive organs, along with secondary sexual characteristics such as facial hair, a deeper voice, and increased muscle mass. It also supports sperm production in the testes as part of the male reproductive system. Estrogen is the main female sex hormone (though present in males in smaller amounts), while glucagon and insulin regulate blood glucose rather than sexual characteristics.
