A woman who lost her husband to brain cancer two years ago has won a legal battle to prevent his frozen sperm being destoyed.
Beth Warren, spoke to ITV's Daybreak programme earlier about how she may have to take her fight back to court again if an appeal is lodged.
Before the fertilisation watchdog announced it was to challenge the High Court ruling, widow Beth Warren had told ITV News she was "elated" at a judge saying she could preserve her late husband's sperm.
She said: "It's absolutely amazing. I knew it could go either way. I am elated.
"Warren's family and friends have told me how proud he would have been of me, and that means a lot.
"Warren was such a fighter, he fought the brain tumor as hard as he possibly could, he stayed positive. We tried and he taught me how to be a fighter."
A widow who won a High Court fight to preserve her late husband's sperm was tonight "downhearted" after the UK fertility regulator was given permission to try to overturn the ruling.
Physiotherapist Beth Warren, 28, from Birmingham, had been "elated" after a High Court judge ruled in her favour following a hearing in London.
But her mood changed when Human Fertilisation and Embryology Authority (Hfea) was given permission to take the case to the Court of Appeal.
"Oh dear," she said. "I thought it was all over."
Widow Beth Warren has won a High Court fight to preserve her dead husband's sperm.
Speaking during the verdict, Judge Mrs Justice Hogg said: "I have held that Mrs Warren has the right to decide to become a parent by her deceased husband.
"She fell in love with a man, cared for him and loved him. I wish her and Mr Brewster's parent well, and ultimately whatever her decision may be I wish her and the family much happiness after such a difficult and sad time".
Widow Beth Warren has said she is "elated" after winning a High Court fight to preserve her late husband's sperm.
Speaking outside the High Court, she said: "I am elated. Every good word in the dictionary. I hadn't dared to let myself believe it would happen."
Widow Beth Warren has won a High Court fight to preserve her late husband's sperm.
The High Court will decide if a widow fighting to stop the destruction of late husband's sperm can keep it in storage for longer than the limit set by the UK fertility regulator.
Physiotherapist Beth Warren, 28, from Birmingham, lost her husband to Warren to cancer two years ago, and placed his sperm in storage.
Mrs Warren, who uses her late husband's first name as her surname, has asked a High Court judge to rule that the sperm could stay in storage for a longer period.
"I have absolutely no idea what the ruling will be," said Mrs Warren. "I think the judge understood that my husband had signed every form he had to. It's all about whether she can find a lawful way to allow it."
The Attorney General's decision to block public disclosure of letters the Prince of Wales wrote to Government ministers was upheld by the High Court today.
Guardian newspaper journalist Rob Evans accused Dominic Grieve of going wrong in law and "overriding an independent and impartial tribunal".
But today the Lord Chief Justice, Lord Judge, sitting with Lord Justice Davis and Mr Justice Globe, refused to overturn Mr Grieve's veto last October on the release of correspondence between Charles and seven Government departments.
They ruled that it was "an exceptional case meriting use of the ministerial veto to prevent disclosure and to safeguard the public interest".
Mr Grieve, the Government's principal legal adviser, said his decision was based on his view that the correspondence was undertaken as part of the Prince's "preparation for becoming king".
Making the letters public could potentially damage the principle of the heir to the throne being politically neutral, and so undermine his ability to fulfil his duties when king, said Mr Grieve.
