A man’s entire world came crashing down when he discovered his wife of six years who he shares two children with was actually his sister. After being adopted immediately after birth, he explained he doesn’t know anything about his biological parents but part of his family history came to light when he underwent some medical tests, the Mirror reports

The man said his wife had fallen ill after their son was born and was in need of a kidney transplant but none of her relatives were a ‘match or a viable donor’. He learned that he was genetically related to his spouse when he decided to donate a kidney to her and discovered they shared an ‘abnormally high match percentage’.
Recalling the uncomfortable situation, he said: “I knew it would be a long shot so I decided to get tested to see if I could donate. I got a call the other day saying that I was a match.
“The doctor then said something about wanting to do additional testing due to some information from the HLA (human leukocyte antigen) tissue test results. I didn’t think much of it and agreed.”
However, the man was horrified to later discover that he was actually related to his wife who he had met while working away eight years ago. He said: “I was shocked and confused.
“He explained that because of how DNA information is passed down through generations a parent to a child could have at least a 50 per cent match and siblings could have a 0-100 per cent match. It was rare to have a high match as husband and wife.”

When the couple first met they had exchanged numbers and agreed to meet up every time the man travelled to her state with work until he was eventually given an opportunity to transfer his job there permanently.
Taking to Reddit to share the news, he wrote in a post: “I don’t know what to do moving forward but I know it may be wrong. She is my wife and the mother of our kids.” Other users rushed to the comments to advise him on how to handle the unfortunate situation.
One user replied: “I mean at this point you are married with children already – you can’t take that back so I don’t see much point in blowing worlds up, I guess.” Somebody else wrote: “You already have kids and they are assumedly healthy since you didn’t mention any crazy abnormalities.
If you’re happy, you’re happy. Donate the kidney to your sister-wife and continue being great parents to your children.”
A third user advised: “Everything’s been great this long, no point changing it.”
