Accepted Answer

Spermatogenesis is a primary sex characteristic in males because it directly involves the production of sperm, which is essential for reproduction. Other options like growth of facial hair, body hair, muscle development, and increase in length of vocal cords are considered secondary sex characteristics, which differentiate the sexes but are not directly involved in reproduction.
