Petition Legalise gender selection in specific circumstances

If a couple have had 3 or more of the same sex children and suffer from gender disappointment it should be legalised as it is in other countries for couples to seek free help and treatment from the NHS to be able to finally get the other sex they want

Many women and men suffer from mental health issues due to wanting a specific sex child after having more than 3 of the same. I believe that giving women or couples that freedom of choice and help will also help with mental health issues later on in life which in turn can completely distroy there life, if it is legalised here in the UK less couple's could suffer from gender disappointment, depression and in turn would result in happy healthy relationships and families.
