Women can delay menopause indefinitely with ovary transplants

Women can remain fertile indefinitely after successful ovarian transplants lead to births and delay the menopause doctors have told a conference.Women can delay menopause indefinitely with ovary transplantsA technique to remove pieces of ovary, store it for decades and then replace it with delicate surgery could effectively put a woman’s menopause ‘on ice’, doctors said.

The only thing preventing them from having babies into their old age would be their physical ability to carry a pregnancy, they said.

The controversial notion would allow career women peace of mind with a fertility insurance policy so they can find a partner, settle down and become financially secure before starting a family.

By delaying the menopause they could also avoid the increased risk of osteoporosis and heart disease that come with the end of their fertile life but may raise the risk of breast and womb cancer.

A conference heard how 28 babies have been born worldwide to patients who either had their own ovarian tissue removed before treatment that would have left them infertile and replaced afterwards or twins where one donated tissue to the other.

Most of the children have been conceived naturally without the need for IVF for drugs.

Dr Sherman Silber, an American surgeon, has been involved in transplants for 11 women at St Luke’s Hospital in St Louis, Missouri, US, said: “A woman born today has a 50 per cent chance of living to 100. That means they are going to be spending half of their lives post-menopause.”

“But you could have grafts removed as a young woman and then have the first replaced as you approach menopausal age. You could then put a slice back every decade.  Some women might want to go through the menopause, but others might not.”

That would mean women would not have to “watch their body clocks”, he said, and would only be physically limited by their ability to carry a baby and give birth.

Transplants carried out eight years ago are still working showing the technique is ‘robust’ and it should no longer be considered experiemental, he said.

One transplant from one 38-year-old to her identical twin, has lasted seven years so far without failing.  In that time the recipient has had two healthy baby boys and a baby girl, all without IVF, conceiving the last aged 45.

Originally it was thought the transplants would only last months, or a few years at most, giving the women just a brief chance of conceiving. But Dr Silber said early hopes had been surpassed.

In Belgium, a woman has given birth after her ovarian tissue was frozen for decade, and in Italy a woman has just had a healthy baby girl after her tissue was frozen for seven years.

He and European colleagues have presented their findings this week at the European Society for Human Reproduction and Embryology (ESHRE) in Istanbul.

They wrote: “All modern women are concerned about what is commonly referred to as their ‘biological clock’ as they worry about the chances of conceiving by the time they have established their career and/or their marriage and their financial stability.

“Most of our cured cancer patients, who have young ovarian tissue frozen, feel almost grateful they had cancer, because otherwise they would share this same fear all modern, liberated women have about their ‘biological clock’.”

The first operation, conducted on Oudara Touirat in Belgium in 2003, led to a pregnancy and successful birth a year later.

Strips of her ovarian tissue were removed before chemotherapy for Hodgkin’s lymphoma and were replaced after she was given the all clear.

The majority of women who have undergone the procedure have had cancer but doctors said it is now time to extend it to others.
