A 24-year-old has become the first in the world to have a baby after having part of her ovarian tissue frozen before the onset of puberty. Researchers at the University of Leeds carried out the procedure to freeze the tissue.

Professor Adam Balen, Chair of the British Fertility Society said:

“This development is wonderful news. Recently scientists from the University of Edinburgh announced that a woman from Edinburgh had become the first in the UK to give birth to a healthy baby boy following a transplant of her ovarian tissue that had been frozen for 10 years. Here in Leeds this is the first baby born from frozen ovarian tissue taken from a girl before she reached puberty and re-implanted as an adult. 

“This is a ground-breaking step in this area of fertility preservation and has the potential to help many young people who face cancer treatment preserve their fertility chances in the future. Storing ovarian tissue was pioneered 20 years ago and now the results are coming through.

“Chemotherapy and radiotherapy can have serious side effects on the reproductive organs. Storing ovarian tissue and more recently storing testicular tissue is becoming more mainstream but we need more centres providing this service and it is important that a multi-disciplinary team of experts is involved to ensure young people in particular are offered this as an option.”
