What's Causing Early Puberty in Girls?



On the January 8th edition of Your Call, we'll have a conversation about why girls are entering puberty earlier than ever before? On the next Your Call, we’ll talk with Doctors Louise Greenspan and Julianna Deardorff, authors of The New Puberty: How to Navigate Early Development in Today's Girls. Just a generation ago, fewer than 5 percent of girls started puberty before the age of 8; today that percentage has more than doubled.  Why is this happening, and what can we do to help girls through this major transition? It's Your Call, with Rose Aguilar, and you.


Dr. Louise Greenspan is a pediatric endocrinologist, focusing on puberty, who works at Kaiser Permanente and is on the faculty at UC San Francisco. 

 Dr. JuliannaDeardorff is a licensed clinical psychologist specializing in adolescent health and an associate professor at UC Berkeley.
