A Team Approach to Compassionate Care
Treating children and teens with non-conforming gender expression, genetic variations in the X and Y chromosomes, or those with differences in genital development can be complex and often requires a team of caregivers. Our board-certified endocrinologists understand the specialized expertise and multidisciplinary approach needed to care for your child.
CHOC specialists work together with you and your child to determine the best course of treatment. Your team may include CHOC experts from our many other specialties, such as cardiology, audiology, adolescent medicine, psychiatry, psychology and social work, plastic surgery and urology and more.
Turner syndrome affects only females, and results when one of the X chromosomes is missing or partially missing. Dr. Mark Daniels discusses Turner syndrome and how it is treated in children and teens.

Transgender Awareness
Transgender and gender non-conforming youth are often socially isolated and at increased risk for depression, substance abuse and suicide, according to Dr. Terez Yonan, adolescent medicine specialist at CHOC. When they are respected, supported and cared for, these risks decrease significantly. In this article, Dr. Yonan offers five ways to support transgender and gender non-conforming family members, friends, classmates, teammates and neighbors.
