However, the reason for the late puberty may be some diseases.

because oftumors of the brain damaging region in which there are the hypothalamus and pituitary.
- Chronic diseases such as diabetes, kidney disease and cystic fibrosis.
Diagnosis and treatment
In order to prevent the chromosomal abnormality in a child taking blood for chromosome study.
A blood test can detect diabetes, anemia and other diseases that can cause delayed puberty.

To identify brain tumors spend x-ray, computed tomography (CT) or
If delay sexual development is caused by a chronic disease, it is necessary to cure the boy from him, after which the rate of ripening completely back to normal.

If the reason for the delay of sexual development was a brain tumor, then surgery is required to remove it.
Treatment of this anomaly in the development of the cause involved in genetics, endocrinology, oncology, etc.
