Hello, it is normal for an 11-year-old child to begin puberty; this does not fall within the definition of precocious puberty. Precocious puberty refers to the onset of secondary sexual characteristics before age 8 in girls and before age 10 in boys. In girls, secondary sexual characteristics typically include breast development, axillary hair growth, changes in external genitalia, menarche (first menstrual period), and pubic hair. The entire process generally takes 1.5 to 6 years, with an average duration of about 4 years. In boys, secondary sexual characteristics first manifest as an increase in testicular volume, followed by penile thickening and lengthening, axillary and pubic hair growth, voice deepening, and the development of masculine physical features such as facial hair. This process usually takes more than 5 years. We hope the above information is helpful to you. Wishing you a happy and healthy life!
