At age 11, Jazz had a hormone blocker implanted in her arm to hinder the growth of her penis, according to the Daily Mail.
Because she didn't develop fully as a male, there wasn't wasn’t enough tissue in her genital area to construct a vagina. Instead, she likely underwent an “experimental” procedure that involved taking out her her peritoneal lining (a thin membrane that surrounds her stomach) to build the vaginal canal—something she discussed on YouTube in May before her surgery.
