Gay couple's joy as they can both be biological dads to their twins
Twins born to a gay couple have two different biological dads after both men were able to successfully fertilise an embryo.
Simon and Graeme Berney Edwards travelled to Canada from London to avail of an advanced IVF treatment that allowed them to fertilise an embryo each.
These embryos were then implanted in surrogate Meg Stone's womb. Nine months later, she gave birth to Calder and Alexandra.
The babies, despite being born at the same time, are technically half-siblings because they both have different fathers.
Mail Online reports that both dads are grateful to Meg for helping them achieve their "dream."
"It really is amazing that Graeme and I have been able to father one of our twins each," said Simon.
"Meg did an amazing job - and it meant that she was actually pregnant by two men at the same time. It's thanks to the wonder of IVF that we have been able to achieve our dream."
The 43-year-old explained that even though Calder and Alexandra are half siblings, they are still classed as twins because they were born from the same womb at the same time.
The couple said that they couldn't decide who they wanted to be the biological father of their twins and were surprised when a doctor outside of the UK said that it could be both of them.
"When we spoke to the doctor at the clinic he stunned us with his reply," said Simon.
"They said that we could have half the embryos fertilised with my sperm and then half with Graeme's sperm."
The twins recently celebrated their first birthday back home in the UK.
Meg, their "tummy mummy" flew over to visit too.
