A new study shows improved rates for vitrification, a newer reproductive choice.

Though egg freezing is still considered experimental by the American Society for Reproductive Medicine, the good news is that the technology involved is improving every day. Doctors at the Northwest Center for Reproductive Sciences, released part of a study this month showing that frozen eggs can be as effective as fresh eggs in helping women achieve an IVF pregnancy.
Though the study is ongoing and has yet to be published, the part that was released -- of egg donors between the ages of 24 and 28 -- found that 85 percent of the eggs survived the thaw after being frozen through the vitrification method instead of the more traditional slow freeze method. As a result, subsequent in vitro fertilization of those eggs generated a 67percent fertilization rate, which was as good as the average success rate for fresh eggs. According to Dr. Gerard Letterie, NCRS's founder, the average fertilization for fresh oocytes in an infertile couple will range from 50 percent to 85 - 90 percent depending on any number of variables such as poor sperm or poor quality oocytes among other issues.
What to do with unused embryos, a byproduct of a booming fertility business, is a question patients are rarely prepared to deal with. They have several choices: finding a research program or fellow patient to accept a donation, discarding the extra embryos, or doing absolutely nothing.
UC Irvine to Pay Another $4.23M in Fertility Cases, Total Now Tops $24M
Two doctors at the center of a medical malpractice case have reportedly fled the country to avoid prosecution for allegedly stealing eggs and embryos from some female patients of a California fertility clinic and giving them to other patients.

Stories of couples making these tough decisions
Experts estimate that hundreds of thousands of embryos have accumulated in fertility clinics throughout the country, some awaiting transfer but many literally frozen in time as parents ask themselves questions few among us ever consider with such immediacy: When does life begin? What does "life" mean, anyway? In a recent survey of 58 couples, researchers from the University of California in San Francisco found that 72 percent were undecided about the fate of their stored embryos.
One of the problems of infertility treatments has been the difficulty of freezing and thawing human eggs. Learn more about why egg freezing has been problematic and how Dr. Terry Schlenker is using a promising new technique to freeze them.

Most Oncologists Fail to Address Fertility Issues with Patients
Researchers conducted a national survey to evaluate knowledge, attitudes, and patterns related to fertility preservation for patients of childbearing age. Of 1,979 oncologists identified, 613 completed the survey. The survey was designed to determine how many oncologists were following the ASCO guidelines for fertility preservation, which suggest that oncologists discuss the risks of infertility and refer all patients of a childbearing age to a fertility-preservation specialist.
"Social egg-freezing" has become more widespread over the past five years as techniques for egg-freezing have improved. Increasing numbers of women in their 30s are opting for a treatment originally designed for those facing fertility-damaging cancer therapies.
