Spermarche
Spermarche, also known as semenarche, is the time at which a male experiences his first ejaculation.
Age of occurrence
Research on the subject has varied for the reasons stated above, as well as changes in the average age of pubescence, which has been decreasing at an average rate of three months a decade.[6] Research from 2010 indicated that the average age for spermarche in the U.S. was 12–16.[7] In 2015, researchers in China determined that the average age for spermarche in China was 14.[8] Historical data from countries including Nigeria[9] and the United States also suggest 14 as an average age.[10]
Context
Various studies have examined the circumstances in which first ejaculation occurred. Most commonly this occurred via a nocturnal emission, with a significant number experiencing semenarche via masturbation, which is very common at that stage. Less commonly, the first ejaculation occurred during sexual intercourse with a partner.[11][9]
