What is the time during which a person reaches sexual maturnity?

Sexual maturity typically occurs during adolescence, which can range from around ages 10 to 19, depending on the individual and their biological sex. For girls, this stage often begins with the onset of menstruation, known as menarche, usually occurring between ages 11 and 14. For boys, sexual maturity is marked by the development of secondary sexual characteristics, such as increased muscle mass and facial hair, often occurring between ages 12 and 16. However, full reproductive maturity can vary, with some individuals reaching their peak fertility in their late teens to early twenties.
