A man in China has been shocked to learn he is intersex after seeking help for a recurring urinary problem for the last 20 years. Chen Li, 33, received the shock of his life after learning that he had ovaries and a uterus and that the persistent urinary problems he faced were actually menstruation, local Greek media reported.

Chen from China's Sichuan province, had surgery to correct irregular urination during puberty. Since then, for more than 20 years, he had experienced recurrent blood in his urine. Last year, during a medical check-up, Chen discovered the true cause of his condition. Chen had female sex chromosomes. His monthly experience of blood in his urine and abdominal discomfort were actually caused by menstruation, reported Greek Reporter.
