Which hormonal change is linked to increased interest in sex during puberty?

• A. Increased testosterone leads to greater interest in sex.
• B. Decreased estrogen leads to more aggressive behavior.
• C. Hormonal changes have no effect on behavior.
• D. Growth spurts occur due to hormones.

Answer: (A)

During puberty, hormones surge and shape sexual development and interest. Testosterone rises significantly and is closely tied to sexual desire, so the idea that increased testosterone leads to greater interest in sex best captures what happens during adolescence. While girls also experience hormonal changes (estrogen and androgens) that influence sexuality, the strongest and most direct link taught about libido in puberty is the rise in testosterone. The other statements don’t fit as well. Estrogen levels don’t typically decrease in puberty to drive aggression, and hormonal changes do affect behavior and libido, so saying they have no effect isn’t accurate. Growth spurts are driven mainly by growth hormone (not sex hormones) and relate to height, not sexual interest.
