To prevent the onset of male puberty (and the growth of beard or body hair), “I Am Jazz” star Jazz Jennings has been undergoing hormone therapy for some time.

Jazz uses blockers that do not allow beard growth and other male characteristics, as well as making use of estrogen to develop a female body.

Although the treatments are expensive (about $ 18,000), her parents support her unconditionally, as Jazz’s father Greg Scott tells ABC:

“We don’t encourage, we support. And we just keep listening to what she tells us.”
