"Because the law has changed, now they have stopped doing this procedure. Nobody in this country has had it done. In Europe and America it's being done successfully - but not here."
She commented: "It makes me angry because it's my tissue and I don't see why I have to fight so hard to have it back."
Miss Oliver had the ovary removed at the Leeds Centre for Reproductive Medicine, now part of Leeds Teaching Hospitals NHS Trust. It was taken out, the tissue separated and put into 20 separate vials. These were frozen, enabling the tissue to be stored indefinitely.
At the time the procedure was highly experimental. However, now it is fairly well established. At least 23 babies have been born across the world after ovaries have been re-planted, or ovarian tissue grafted back on.
Sherman Silber, the American surgeon who carried out the first whole ovary transplant, has even suggested all women looking to conceive in their late 30s or 40s should consider having a thin slice of ovarian tissue frozen in their 20s, to bank a batch of healthy eggs.
Miss Oliver first contacted the Leeds unit in 2009 anticipating it would take some time to set up the operation. The special needs teacher, who is single, said she wanted to get pregnant with donated sperm.
The following February her consultant told her she could have the operation in six to nine months, she said.
But she added: "Two years later I'm still waiting. They are trying to push it forward but I've been told there is still no progress as there is not a satisfactory unit in any hospital in this country to perform the procedure."
Procedures involving grafts or implantation of ovarian tissue are regulated by the Human Tissue Authority.
An HTA spokesman said British regulations in this area were tightened in July 2007, in response to the EU Tissue and Cells Directive. This directive, she said, "set out to establish a harmonised approach to the regulation of tissues and cells Europe".
As is often the case, however, European directives are interpreted in different ways in different countries. British authorities often err on the safe side, resulting in a more restrictive approach.
A spokesman for Leeds Teaching Hospitals said: "Like other trusts across the country, we don?t as yet have the facilities to meet the requirements set out in this legislation.
"This is a complex area which we are looking into further in the hope we can make progress on it soon as we can fully understand the frustration of Ms Oliver."
He was unable to explain exactly why the legislation prevented the operation from taking place.
