men DO reach their physical peak at age 18 give or take a year or two so i dont understand why you had a problem with that answer..i thought this was common knowledge??? men 18, women late 20's--its always been a topic of discussion as to why the 2 sexes have such a wide gap between their peaks.here is no age for that. It's all over the board. Some men are in the best shape of their life at 40 health wise and physical wise. I'm 19 and the time my body was at my best was 16. So it's all over the place there is no average for all men.
Usually the capability to ejaculate semen comes about one to two years after puberty starts -- often about the time pubic hair begins to grow and a boy begins his growth spurt. The average age for starting puberty is 11 1/2. This makes the average age to ejaculating semen around the age of 13. But this is only an average. Puberty in boys is considered normal if it starts as early as 9 or as late as 16. Hence, some boys, even though they are normal, will not gain the ability to ejaculate until they are nearly 18 years of age or they may start as soon as 10. Usually when a boy begins to develop too early, it is an indication of problem.
