Depends on the type of abortion. After an abortion, the physician or nurse is required to put the torn pieces back together again on a tray. This ensures 'they got it all' and prevents further infection.
A fetus in the 19th week of gestation would have an identifiable sex. The sex would be documented in the medical records as part of the documentation of the abortion procedure. As an adult, she is entitled to access her medical records or as a minor with legal counsel.
