Puberty Is Not Synonymous with Sexual Maturity

Puberty in the male is when he is first able to produce suf- ficient numbers of sperm to impregnate a female. For prac­tical reasons, for bulls, boars, rams, and stallions, this could be defined as the age when the ejaculate contains 50 ? IO⁶ spermatozoa, of which 10% or more are motile. It must be remembered that puberty is not synonymous with sexual maturity, which can occur months to years later, depending on the species.
