The CDC's recommendation for the initial administration of HPV vaccine in males is:
age 11-12 years.
between 13 and 16 years.
between 13 and 26 years.
8-9 years of age.
The Correct Answer is A
Rationale:
A. The CDC recommends that the HPV vaccine series be initiated in males at ages 11–12 years for optimal immunogenic response and before potential exposure to HPV through sexual activity.
B. While vaccination between ages 13 and 16 is still effective, it is considered a catch-up period rather than the recommended age for routine initiation.
C. Ages 13–26 include catch-up vaccination for those who were not vaccinated earlier, but this is not the routine initial recommendation.
D. Age 8–9 is earlier than the recommended age for HPV vaccination and is generally not indicated unless specific high-risk factors are present.

Correct Answer is D
Explanation
Rationale:
A. The appearance of downy pubic hair occurs after the initial signs of puberty and typically represents Tanner stage 2–3 development.
B. Enlargement and lengthening of the penis usually occur after testicular enlargement, often a few months later, as puberty progresses.
C. Axillary and facial hair develop in later stages of puberty and are not initial indicators of sexual maturation in males.
D. Enlargement of the testicles and scrotum is the first and most reliable sign of puberty in males, generally occurring between ages 9 and 14. Testicular growth reflects activation of the hypothalamic-pituitary-gonadal axis, leading to increased testosterone production and the subsequent development of secondary sexual characteristics. Monitoring testicular size is therefore a key component in assessing the onset and progression of male puberty.
