We have noted that unusual boys may ejaculate as early as eight years of age. As we may expect, there are surprisingly late upper extremes as well.

There are of course sad cases of life-long ejaculatory impotence. But assuming that most men start ejaculating at some time in their lives what is the latest age for such a commencement? According to Kinsey the latest ages of first ejaculation reliably recorded "are 21 for two apparently healthy males, 24 for a religiously inhibited individual, and 22 and 24 for two males with hormonal deficiencies."
