Australian first: pregnancy using frozen ovarian tissue

Doctors at Monash IVF implanted ovarian tissue into a 43-year-old Melbourne woman, six years after she beat breast cancer.

The tissue was removed from the woman in 2005 before she underwent cancer treatment and in April this year it was implanted, allowing natural ovulation to resume.

Monash IVF director Professor Gab Kovacs presided over the process, telling AAP the woman was now six and a half weeks pregnant.

He said it was only the 20th pregnancy worldwide using the method.

"Fertility doctors all see young women with cancer who want to preserve their fertility,” Professor Kovacs said.
