Oocyte Freezing As more and more women opt for fertility preservation through egg retrieval, British gynecologists warn about the risk of failure, underestimated by women.
This is an option that more and more women are seriously considering. Oocyte freezing, after ovarian stimulation and puncture, appears as an ideal approach to maintaining fertility, and being sure to be able to get pregnant when the time is right.
With a career and difficulty in finding a stable relationship, many women find themselves reluctant to have a pregnancy between the ages of 20 and 35, the age group where female fertility is highest.
As a result, to increase their chances of having a baby spent 35-40 years, some have their eggs frozen, especially in Spain.
However, freezing eggs does not guarantee pregnancy. Although frozen oocytes in their thirties will be of better quality than eggs in a 40-year-old woman, the IVF challenge remains. Mature embryos must survive and develop to the blastocyst stage and then be implanted. There, it is necessary that an implantation takes place so that the pregnancy begins.
British gynecologists have discussed this difficult topic, and reported on their discussions in the BJOG International Journal of Obstetrics and Gynecology.
"The success rates of egg freezing have improved dramatically in recent years, giving women the opportunity to freeze their eggs for social reasons. But if women are to be supported in their choices, they must also be informed of relatively low success rates, high costs and side effects, "said Professor Adam Balen of the Royal College of Obstetricians and Gynecologists. The latter states that the best time to freeze his eggs is in his twenties, and certainly not after 37 years.
A fertility preservation measure that indirectly encourages late pregnancies
For her part, Dr. Timothy Bracewell-Milnes of the Imperial College of London believes that most women take measures to preserve their fertility at an advanced age. Instead of being a planned and thoughtful choice, oocyte freezing is more of a last-minute option, and oocyte quality is reduced by 35 years. Obstetric gynecologists also believe that egg freezing indirectly encourages women to have children in old age, which significantly increases the risk of medical complications during pregnancy (pre-eclampsia, premature labor, gestational diabetes, etc.). .
To hope to become pregnant, a woman in her late thirties should freeze 30 oocytes, which requires on average three cycles of ovarian stimulation, and which has a considerable cost to society, say doctors. The latter therefore invite women concerned by this approach to learn well in advance, to know their real chances of success, and plan their preservation of fertility accordingly.
