A Welsh woman is calling for families in the UK to have the right to decide on the gender of their children. She had three boys and wanted a girl, so contacted a fertility specialist in America.
The gender selection treatment was a success and she now has a daughter. It's currently not legal in the UK, and we have disguised the mother's identity and voice for her protection.
Alexandra Lodge reports.
It's a secret Stacey and her husband have hidden for years.
After having three boys, they flew to America to have gender selection treatment - to guarantee their fourth child would be a girl.
Stacey paid around £20,000 for two cycles of Gendersure treatment with a fertility specialist in California.
Afer a couple of attempts, the treatment worked. In October 2010, Stacey fell pregnant with the baby girl she'd wanted.
Now she believes this procedure should be available in the UK so more parents are able to choose the sex of their children.
Treatment of this kind is still considered controversial by many, with critics arguing that 'playing God' or toying with nature could lead to gender discrimination
Stacey says the risk and the cost was worth it, and wants to treatment to be made available in the UK.
