Abstract
The age of occurrence of the 1st conscious ejaculation was registered in 263 boys belonging to 2 categories. One group of 128 boys (70 normal controls, 22 boys with unilateral cryptorchidism with normal puberty and 36 boys with delayed puberty) was under regular follow-up throughout puberty; all underwent a complete physical examination at intervals of 3-6 mo., and in most a wrist X-ray was made within 3 mo. of the 1st ejaculation. A group of 135 boys examined and questioned at their school served as additional controls. Of these, 80 reported ejaculations. Despite a wide range in the chronological age at occurrence of the 1st conscious ejaculation, the mean bone age in all groups, including that with delayed puberty, was 13 1/2 .+-. 1/2 yr (SD), with a range from 12 1/2-15 1/2 yr. There was no correlation between the age at 1st ejaculation and testicular volume, pubic hair or penis length. It is proposed that the age at the 1st conscious ejaculation be used as an index of maturation in male puberty.
