An Australian woman claims an IVF clinic lost her last frozen embryo, ruining her hopes of motherhood.

The woman, said to be in her late 40s, alleges Melbourne IVF staff allowed her potential baby to be destroyed.

She claims to have paid storage fees for years to preserve on ice the last of 13 embryos created during infertility treatment in 2003 and 2004.

But the embryo allegedly couldn't be found for a final round of treatment in 2007.

The woman has launched legal action in the County Court against Melbourne IVF, which is expected to defend the claim.

Court documents filed by the woman's lawyers this week claim the would-be mom started IVF treatment in October 2003.

A total of 31 eggs were harvested and 13 of the resulting embryos were frozen, the suit says.

The woman alleges Melbourne IVF's Dr. Geoffrey Clarke assured her one embryo would be kept in storage for later use.

After unsuccessful attempts to get pregnant, the woman changed to another specialist — Melbourne IVF director Dr. Jim Tsaltas — in October 2006.
