AN AUSTRALIAN MOTHER has given birth to non-identical twins which were conceived 10 days apart.
Brisbane couple Kate and Peter Hill only had sex once, but a medical phenomenon known as superfetation led her to become pregnant twice in ten days.
The couple told 7News that the baby girls were born at the same time, but were different sizes, weights and at different stages of gestational development.
They also have different blood types.
“We actually did not realise how special that (form of conception) was until they were born,” Kate told 7′s Today Tonight show.
“What makes this case even more rare, is that my husband and I only had intercourse one time – his sperm stayed alive for 10 days to fertilise the second egg released.”
Superfetation is so rare – there are only around 10 instances known in the world – the couple’s doctor had to Google it.
