Abstract
Complete physical examinations and bone age determinations are performed regularly in all children being followed longitudinally in our clinic. Boys approaching puberty are asked at each visit whether there has been a first ejaculation. A survey was made of 158 boys (97 normals (N), 36 with delayed puberty (DP) and 25 with cryptorchidism (Cr)) in whom it was possible to carry out an evaluation within an approximate 3 months of the first conscious ejaculation. Sixty four healthy school boys served as additional controls. The main findings were:
It is evident that the first ejaculation occurs within a narrow range of bone age although chronological age shows a much wider variance, as do testicular volume and secondary sexual signs. It is concluded that registration of the first conscious ejaculation may constitute an useful index of maturation in the male.
