Gynecologists who want to identify the sex of genitals will ask why they need to identify the sex of genitals, and they must be gynecologists at the level of top three hospitals, that is, top three hospitals. After signing, they need the official seal of the hospital, that is, they have to go to the higher authorities of the hospital to affix the official seal.
