Spermarche
Updated:Spermarche refers to the onset of sperm production in males, typically occurring during puberty. It marks the beginning of a male's ability to produce viable sperm and, consequently, the potential for biological fatherhood. This milestone usually happens between the ages of 11 and 15, though the exact timing can vary widely among individuals.
Additional Information
Spermarche is often accompanied by other physical changes associated with male puberty, such as the growth of body hair, voice deepening, and increased muscle mass. Unlike menarche (the first menstruation in females), spermarche is not always a noticeable event and may occur without the individual's awareness.
The production of sperm begins in the testicles, stimulated by hormonal changes during puberty. While spermarche indicates the start of sperm production, it doesn't necessarily mean that a male is immediately fertile. It may take several months or even years after spermarche for sperm production to reach levels capable of causing pregnancy.
