Premature sexual development in girls can have significant impacts on their future, with one of the most common issues being effects on height. Premature sexual development can cause bone age to advance much earlier than in peers, which can lead to premature closure of the growth plates and result in a shorter stature. Additionally, it can have profound impacts on the individual's psychological and emotional well-being, leading to issues such as low self-esteem and anxiety. Premature sexual development can also cause early breast development and early menstruation, which may lead to premature romantic relationships and other early maturation behaviors. Therefore, it has a substantial effect on both the physical and mental development of girls. For such patients, it is crucial to detect, diagnose, and treat the condition early.
