Big Brother star Chantelle Houghton has been told that she has little chance of conceiving a baby naturally after years of extreme dieting.
The 27-year-old reality TV star said she had decided to speak out to raise awareness of her condition.
Chantelle said she went to a gynaecology and fertility clinic after getting pain in her left ovary.
She told Heat magazine: "I was at home and had no idea they (the results) were going to arrive in the post.
"I opened it and saw numbers and a graph and there were all these words like 'low' and 'diminished'."
Chantelle, who went to see her doctor two days later, said: "He told me that I'd never be able to conceive naturally... that I had low fertility and that if I wanted to have a baby, I'd have to have IVF.
"He said that if I'd waited another three years, I would never be able to have children at all. I wouldn't have any eggs left."
She added: "There's always the chance I could miraculously fall pregnant naturally, but it's so remote."
Chantelle, currently dating Alex Reid, said: "Ultimately it's my fault."
She added: "Because of my obsession with food and my crash dieting when I had bulimia, I've ruined my chances of having a baby naturally."
