Girls typically begin the process of sexual maturation, also known as puberty, between the ages of 8 and 13.
While there's no single "maturity age," this range represents the period when most girls start experiencing physical changes associated with puberty. This includes breast development, the start of menstruation (menarche), and changes in body shape.
Here's a breakdown:
- Typical Onset: 8-13 years old.
- Individual Variation: The exact timing varies greatly from girl to girl and is influenced by genetics, nutrition, and overall health.
- Puberty Duration: The entire process of puberty usually takes about 4 years to complete.
It's important to note that early or late onset of puberty can occur. If puberty begins significantly before age 8, it's considered precocious puberty and warrants medical evaluation. Similarly, if puberty hasn't started by age 13, it's advisable to consult a doctor to rule out any underlying medical conditions.
