Here's how a gay man became the brother of his own son

A UK-based man has become the first single man to have a baby through surrogacy and the first to use his own mother as a surrogate.

Kyle Casson, who is gay and desperately wanted to be a father, turned to his 45-year-old mother Anne-Marie to carry a donor egg that he had fertilised after being turned away by surrogacy clinics across the country, the Daily Express reported.

The 27-year-old Casson welcomed son Miles into the world eight months ago, but in the eyes of the law, Casson is also Miles's brother because Anne-Marie gave birth to him.

The supermarket worker from Doncaster said that he understands that not everyone will agree with it, but they can have their opinions, adding that he has a son and he is very happy.

Casson noted that as long as people can provide a home, and they have the support, he doesn't see why anyone should be denied the right to be a parent, adding that he paid for it himself, it's not taxpayers' money, he owns his own home and is going back to work.

Anne-Marie said that when Casson first came to her and his dad, she thought "she could do it" and when some people found out, they said "urgh", but they don't understand that he is not biologically tied to her, other than he's her grandson.

She added that she love being a parent and for Casson to experience that, she would do that for him.

However, the baby is legally Kyle's mum and dad's, after a High Court adoption ruling said the woman who carried the child is the legal mother. Her husband is the father because he consented to the pregnancy.

The judge argued adoption would not break laws because the Miles and Kyle are legally related as brothers and social workers backed the adoption, saying it would "strengthen the bond the father and child already share.
