How about the fertility capacity of frozen eggs?
11/20/2015 01:47:00 AM
Before we decide to cryopreserve our own eggs for the future use,
we must think about the impact of freezing.
According to many scientific articles, the risk of egg freezing is related to the maternal age, not the procedure itself. The findings are concordant to the report released by Stork Fertility Center in newest annual meeting of Taiwan Society of Reproductive Medicine.
Twins born through IVF "more likely to suffer problems"

Twins born through fertility treatment and their mothers are far more likely to suffer problems than single births, new studies show. Until recently fertility clinics implanted several embryos to increase the chance of conception, but the practise led to women regularly having more than one child.
Now new research has shown that even giving birth to twins through fertility treatment, such as IVF, substantially increases the risk to both mother and children. They were five times more likely to need a Caesarean section and 10 times more likely to be born prematurely.
Prof Barbara Luke, at Michigan State University, looked at the birth outcomes for 6,000 single pregnancies and 2,500 twins. "And what we found was that being a twin versus a singleton at birth increased the risk for all outcomes except for of course large for age," she said. Multiple pregnancy is the single biggest risk of fertility treatment, according to the Human Fertilization and Embryology Authority.
It increases the risk of stillbirth, neonatal death and disability in children born. It also increases the risk of dangerous complications to the mother, such as late miscarriage, high blood pressure and pre-eclampsia.
On average, one-in-five IVF pregnancies are a multiple pregnancy compared to one-in-80 for women who conceive naturally. UK guidelines advise that wherever possible a single embryo only should be transferred, but some clinics still put back more – sometimes because the patient wrongly thinks it improves their chances. However, the research suggests that it is safer to transfer single embryos.
Dr Rebecca Sokol, president of the American Society for Reproductive Medicine, said: "We have long known the dangers of high order multiple pregnancies.
"This research shows us how risky even twin pregnancies can be. Clearly, the trend toward using single embryo transfer needs to continue."
The research was presented at the American Society for Reproductive Medicine annual meeting in Honolulu, Hawaii.
