Final answer:
Sexual arousal capacity develops during puberty, which is the stage when individuals become sexually mature, typically occurring between ages 12 to 18 for males.
Step-by-step explanation:
The capacity for sexual arousal is not something that is fully developed at birth but rather emerges significantly during a period known as puberty. While infants may display initial physiological differences in reproductive organs, these do not encompass the full context of sexual arousal and maturity that develops later in life.
Sexual Development in Males specifically follows a predictable sequence that begins subtly in childhood and culminates during the adolescent years. Both males and females undergo hormonal changes during puberty, involving a release of hormones from the hypothalamus, anterior pituitary, and the gonads that stimulate the development of secondary sex characteristics and maturation of reproductive systems. For males, this period typically ranges from ages 12 to 18.
Therefore, puberty is when individuals develop a capacity for sexual arousal, which becomes apparent due to hormonal triggers and the subsequent physiological changes. As such, the correct answer to the student’s question would be C) Develops at puberty. This is when the male reproductive system which forms before birth, becomes capable of reproduction, marking the onset of sexual maturity.
