Primary sex characteristics are those directly related to the sex organs . In males, the first stages of puberty involve growth of the testes and scrotum, followed by growth of the penis. [51] At the time that the penis develops, the seminal vesicles , the prostate , and the bulbourethral gland also enlarge and develop. The first ejaculation of seminal fluid generally occurs about one year after the beginning of accelerated penis growth, although this is often determined culturally rather than biologically, since for many boys first ejaculation occurs as a result of masturbation.
