A nurse is teaching a group of parents about the role of testosterone in puberty for boys
To evaluate the group's understanding, the nurse asks, "What physiologic effects related to testoste-rone can you expect to see in your sons?" Which responses indicate an understanding of the role of testosterone in male puberty? (Select all that apply.) a. "It promotes skeletal muscle growth."
b. "It increases height and weight."
c. "It delays epiphyseal closure."
d. "It causes a high-pitched voice."
e. "It causes acne."
A, B, E
The physiologic effects associated with androgen therapy are promotion of skeletal muscle growth, an increase in height and weight, acceleration of epiphyseal closure, deepening of the voice, oily skin, and acne. Androgen therapy accelerates epiphyseal closure; it does not delay it. Androgen therapy deepens the voice rather than raising the pitch.
