Gets His DNA Test Results And Finds Out He’s Dating His Half-Sister


An unnamed man took to Reddit to share his dismay after the results from his and his girlfriend’s genetic test revealed they share the same father.

In a detailed post, he explained that the pair were both conceived by in-vitro fertilisation via sperm donors meaning the results claim they are the children of the same male liquid donor.

“Christmas day rolls around, and Sarah had bought the both of us 23andme DNA kits. The thing is, is that we were both conceived by in-vitro fertilisation via donors,” he explained.

“Both of our fathers were infertile so our parents had no choice. Deep down, the both of us were hoping to find our biological fathers through the service.”

The pair finally got their results and “all was well until we arrived at the “DNA relatives” section.” The results had his girlfriend’s name at the top and claimed she was his half-sister, with the pair sharing 27% of the same DNA. He then explained how the outcome could be true, surmising that both their mothers must have been inseminated with the same man’s sample.


“What are the odds, right? The fact that we’re from the same town certainly increased the odds but still.”

He told Reddit users that the news had left him and Sarah in complete shock and feeling “traumatised” at the knowledge that their year-long relationship. Some readers were quick to share their thoughts and revealed their sadness for the couple.

“I think you should definitely talk to a professional with this traumatising situation to help you understand that it wasn’t anyone’s fault. You simply didn’t know,” one wrote.

“Makes you wonder if this service should continue to be provided. A company basically created a large number of half-siblings in upcoming generations, which is basically on a large scale. Most likely women or couples chose male liquid from a limited number of men,” another mused.
