A man who went to hospital with stomach ache was told it was period pains and that he is in fact a woman. The 44-year-old known as Chen from Zhejiang province, China, was discovered to have full female reproductive organs as well as a penis – which had kept him and his wife happy for the past 10 years, according to odditycentral.com.

Being ‘intersex’ affects one in every 2,000 births in the United Kingdom according to researchers. At the moment, there are roughly 30,000 intersex people living in different parts of the UK. People with this rare condition may be genetically female, but physiologically male. Some, in fact, will be pure hermaphrodites, producing both eggs and sperm.

The Chinese man visited his doctor with his wife in Yongkang, where a CT scan showed he had both uterus and ovaries. A further examination revealed he had a pair of female sex chromosomes. Therefore, genetically, Chen is in fact a woman. Doctors however, said it was too late for him to seek medical solution to the problem.
