The earliest ejaculation remembered by any of the "apparently normal males" surveyed by
Kinsey was at the age
of eight: this age was noted by three males. The history was also taken of one unusual boy, a
Negro interviewed
when he was 12, who reckoned he first ejaculated at the age of six. A clinician had diagnosed
the boy as
"idiopathically precocious in development." In the literature- Kinsey quotes three cases - there
are clinical
instances of still younger ages. Non-motile sperm have been detected in urine after prostate
massage at four and
half years. Kinsey opts for eight as the earliest reliably recorded ejaculation .
