66-year-old man goes to the doctor, finds out he's a woman

It happened in Hong Kong, where the man went to see a doctor for a swollen abdomen, which actually turned out to be a cyst on his ovary.

The subject suffered from two rare genetic disorders, one of which, congenital adrenal hyperplasia, increases male hormones meaning they had a beard and a "micropenis", the Hong Kong Medical Journal reported.

The other - Turner Syndrome - affects peoples X and Y chromosomes.

The patient, who grew up as an orphan, was found to have no testes, and stopped growing after puberty at the age of 10.

The Vietnam-born Chinese patient decided to continue "perceiving himself as having a male gender with the possible need of testosterone replacement."
