  1. Girls mature earlier because of hormonal changes. Girls start puberty at 9-10 years old while boys usually reach puberty at 12-13 years old. In addition to that, girls develop faster than boys. As soon as they hit puberty, girls start growing breasts and developing pubic hair. Boys also grow facial hair and begin to develop muscles.

    As soon as they turn 15, girls begin menstruating. They also start experiencing mood swings and emotional instability.

    When you talk about hormones, they play a major role in making girls mature faster. For example, estrogen helps stimulate breast development. Testosterone stimulates muscle growth. And progesterone makes them gain weight.

    Hormones affect both genders equally. But, the differences lie in the timing of the onset. Girls tend to mature faster than boys.

    You might ask why girls mature faster than boys. Well, the answer lies in genetics. Boys and girls have different genes which determine their physical appearance.

    For instance, boys have XY chromosomes whereas girls have XX chromosomes. X chromosomes contain genes responsible for determining traits such as height, body shape, and bone structure. On the contrary, Y chromosome contains genes responsible for determining characteristics such as size of testicles, penis length, and sperm count.

    This is one reason why boys mature later than girls. Their bodies take longer to produce testosterone. Therefore, they don’t experience the effects of testosterone until they’re older.

    The Biological Reasons Girls Start Menstruation Early

    Girls begin menstruating at age 12, on average, according to the National Institutes of Health (NIH). This means that most girls enter puberty between ages 11 and 13. The reason behind this phenomenon is still unknown.

    However, there are several theories regarding why girls mature earlier than boys. One theory suggests that estrogen plays a role in the development of female secondary sex characteristics, including breast growth and pubic hair. Another theory states that testosterone may play a role in the development and progression of puberty.

    Regardless of the cause, it’s important for parents to be aware of the signs of puberty in order to help guide their daughters through this process safely.

    The Psychological Reasons Girls Start Menstruating Early

    Girls begin menstruating at age 9, whereas boys typically reach puberty between ages 11 and 13. The reason for this difference is unknown, although there are several psychological reasons girls mature earlier than boys.

    One theory suggests that girls’ bodies are programmed to produce estrogen at a younger age because it helps them develop faster. Another theory suggests that girls may be biologically predisposed to become sexually active sooner than boys.

    Regardless of the cause, the fact remains that girls mature earlier than boys, and that means girls need to start thinking about sex earlier too.

    The Social Reasons Girls Start Menstruatin Early

    Girls begin menstruating at age 10, and most women reach menopause between ages 45 and 55. This means that most women experience menarche (the onset of menstruation) during puberty, when they’re still children.

    This makes sense because girls’ bodies are not fully developed until they’ve reached puberty. So, there must be some biological reason behind this phenomenon.

    One theory suggests that girls develop earlier than boys because they need to catch up after being out of school for several years. Another theory says that girls mature faster because they spend more time playing outside and participating in sports.

    Whatever the reason, it’s important to understand why girls mature early. The sooner we learn why girls mature early, the better prepared we’ll be to help them through this transition.


    Most girls will begin their menstrual cycle by age 11, with some starting earlier than this. This means that many girls will experience puberty before they reach the legal drinking age.
