Doctors in a Chinese hospital conducted a surgery in which a two-year old boy 'gave birth' to his twin brother.
Xiao Feng's parents revealed that they brought their son to the hospital as he was having difficulty in breathing due to an abdominal swelling.
However following extensive tests, the doctors at the hospital were shocked to find that he was carrying the undeveloped fetus of his twin inside his stomach.
The doctors diagnosed the condition as cryptodidymus, a condition linked to conjoined twins where one twin is concealed in the body of another. The doctors said that the fetus inside Xiao Feng was growing and had taken up two-thirds of his stomach, developing spine, fingers, and toes.
