Comments from Zeng's roommates in college and information sought on the Internet encouraged the student to seek medical attention to validate her inner and outward appearance. As a result, Zeng and her mother attended a scheduled doctor’s appointment at Southwest Hospital where Dr. Lu Gensheng discovered that Zeng was born as a hermaphrodite.
Doctor Lu revealed to Zeng and her mother that Zeng has small breasts, small testis, no uterus, a vagina and a small penis.
Doctor Lu also shared that the student has the option to reshape her body into either male or female, but in either case she would never be fertile - meaning she cannot have children.
