Frozen Egg Pregnancy is First for Kansas City
A 31-year-old woman from Kansas City, Missouri, has become the first woman in Kansas or the Kansas City area to have her eggs frozen in a rare procedure, then later have the eggs thawed and fertilized, resulting in a pregnancy.
The woman had all the procedures performed in the Kansas City metropolitan area by Sam Kim, MD, who heads the Reproductive Endocrinology and Infertility Clinic of The University of Kansas Hospital and The University of Kansas Physicians.
Dr. Kim said the successful procedure opens many doors for women in terms of reproductive options.
“First, a woman who wants to delay pregnancy because of career, marital status or other life situation can have her eggs frozen at a younger age to increase chances of a successful pregnancy later in life. Most importantly, a woman facing a health challenge such as cancer can have her eggs frozen before beginning treatment, and then when she is cancer free, she can use the frozen eggs even if the treatment has damaged her ovaries,” said Dr. Kim.
While frozen sperm and frozen embryos are common, Dr. Kim said eggs are more delicate, requiring a lot more sensitive work to freeze them properly. That is why there have only been a few instances of successful pregnancies using frozen egg technologies. The success rates with egg freezing have improved with the introduction of the new technology called vitrification, which Dr. Kim modified in his clinic to make it more efficient.
In this instance, the patient had her eggs frozen for personal reasons while she and her husband debated pregnancy options. When they decided a few months later, the stored eggs were used and the patient became pregnant in late August, 2011.
Dr. Kim’s clinic is the only one in the region capable of freezing eggs and successfully replanting them. Dr. Kim also performed the area’s first ovarian tissue transplant in 2010.
