New technique could help cancer patients or women who want to delay childbirth

MONDAY, Nov. 10 (HealthDay News) — Scientists are reporting the ability to freeze and transplant ovaries, a development that could help preserve fertility in women facing cancer therapy.
"We can transplant ovaries without any loss of ovarian tissue or eggs, and it functions perfectly normally whether it’s fresh or frozen," said co-researcher Dr. Sherman Silber, director of the Infertility Center of St. Louis at St. Luke’s Hospital.
Silber said the technique could also be used by women who want to delay having children. He reported the findings Nov. 10 at the American Society for Reproductive Medicine annual meeting, in San Francisco.
In one paper, Silber reported that he and his colleagues had transplanted an ovary from one identical twin to her twin sister, allowing the twin with premature ovarian failure to conceive a child. One year after the transplant, the twin with the transplanted ovary had become pregnant.
But, Silber said, the ability to remove an ovary, freeze it and put it back into the same woman represents the real breakthrough. "We can freeze the ovaries of young women who are going to lose their fertility over time [...] Continue Reading…

Egg Freezing (Oocyte cryopreservation) has many potential benefits including improved efficiency of ART and as an alternative to embryo freezing for religious reasons and/or in compliance with certain legal statutes. Cryopreservation may lessen the severity of OHSS by avoiding embryo transfer in patients with excessive ovarian stimulation. Donor oocyte recipient patients may benefit, as would some in the treatment of congenital disorders or to prevent ovarian loss secondary to surgery, or chemotherapy/radiation. It may be a potential treatment of premature ovarian failure, where there is a significant familial component. While all of these potential indications are exciting and may give many patients great hope, oocyte cryopreservation should still be considered investigational in nature and only be done under the auspices of an [...] Continue Reading…

Fertility preservation is a hot service offered by many fertility clinics today. The most common and successful means to preserve fertility is through egg freezing (also known as oocyte cryopreservation). More than 500 babies have been born from this technique worldwide. Egg freezing is a process whereby eggs are stimulated in the woman’s ovaries and then harvested and stored for use at a later date. This can be done in the setting of a medical emergency, such as a newly-diagnosed cancer, or for personal reasons e.g. a woman who is not in a life situation currently conducive to childbearing.
With age, women’s eggs declines in both quantity and quality
It is important to understand that egg quality is best when a woman is in her reproductive prime, meaning between the ages of 16 and 28. Most women today are not looking to mother a child in their teens and quite frankly, our society has stigmatized childbearing at the age when women are most fertile. This leaves many young people looking for ways to protect themselves against pregnancy in their early prime years and then facing the choice of when childbearing is optimum. In some instances, this decision is easy – when [...] Continue Reading…

"Soon, IVF may be better than natural conception for many, perhaps most, couples, not just those who can’t make babies the usual way", writes Helen Joyce. Your grandchildren may not be conceived the way you were …
From INTELLIGENT LIFE magazine, Autumn 2008
It’s an unseasonably cold Saturday in July and I’m standing, shivering, in the grounds of Bourn Hall, a Jacobean manor house in Cambridgeshire. All around are happy families, chatting and taking photographs. It feels like a wedding, even down to the disappointing weather, but it is in fact a birthday. The guest of honour, Louise Brown, the world’s first "test-tube baby", is about to turn 30. When she was two, Patrick Steptoe and Robert Edwards, the doctors who helped her mother to bypass her blocked Fallopian tubes and conceive, set up the world’s first dedicated fertility clinic here. Invitations to the birthday party have gone out to IVF children born every year since. Steptoe died 20 years ago; Bob Edwards, frail but doing well for an 82-year-old, is holding up under the hugs and thanks of his creations. Many of the parents want pictures of Louise Brown with their offspring, and she is graciously obliging. About half [...] Continue Reading…
