Treatment

There is often no treatment for those who are healthy and just starting later than their peers. They will continue to be monitored.Other treatment depends on the cause. For those who have a chronic underlying disease, treatment is aimed at the specific condition. After the condition is treated, puberty often begins on its own.For others treatments may include:

Sex Hormone Replacement

Sex hormones will help begin sexual development. They may be given to those with chromosomal abnormalities. This can include Turner syndrome or Klinefelter syndrome. Hormones may also be given to teens who are severely delayed or overly stressed by their lack of development.Other medications may be added to sex hormone replacement medications. They may help increase height in children and young adults with constitutional delay of puberty.

Psychological Support

Counseling may be suggested for adolescents who are struggling with the delay. This may help the child cope with social pressures.

Ongoing Monitoring

Your child’s height, weight, and sexual development will continued to be monitored. This will help determine if any treatment has been effective.

Prevention

Most causes of delayed sexual development cannot be prevented. To help reduce the chance, make sure your child maintains a healthy lifestyle. This includes making sure your child is eating well and getting nutrients. Make sure any underlying illness is treated.
