The term for a male's first ejaculation is spermarche, which usually occurs around the age of 13. While this event is a sign of beginning sexual development, it is not necessarily an indicator of complete sexual maturation, as puberty and sexual development occur over a period of years. Menarche, on the other hand, refers to a female's first menstrual period and is not applicable in this case.
