The UK Daily Mail:

A married woman whose husband donated sperm without her knowledge is calling for clinics to be forced to ask for a wife's consent.

The unnamed mother-of-one from Surrey said she feared that children fathered with the sperm – who would be half-brothers or sisters of her son – may one day 'disrupt' the family by getting in touch.

She has written to the Human Fertilisation and Embryology Authority calling for guidelines on sperm donation to include the spouse's views – and says the sperm should be treated as a joint 'marital asset'.

A controversial ruling in 2005 meant all children born through sperm donation – up to ten families are allowed per donor – have the right to trace their biological father when they reach adulthood.

In her heartfelt letter to the fertility watchdog, she told how her husband had donated sperm against her wishes after suffering Post Traumatic Stress Disorder following the birth of their child.

But if the children he fathers – to help infertile couples or single women – contacted her in the future, she would 'not feel able to push them away'.

The businesswoman said: 'I am personally in this situation with my husband having donated sperm against my wishes when he was suffering from PTSD.
