Egg cell was frozen in liquid nitrogen for 14 years - woman becomes mother
Some women who want to have children postpone their plans to later years because, for example, they want to have enough time for their careers. You can freeze egg cells to fulfill your desire to have children later. An Argentine woman also used this opportunity. She became a mother thanks to a frozen egg cell for 14 years.
Postpone having a child until later
There are more and more women who want to have children, but postpone their plans to later years, for example to have enough time for their careers. So-called “social freezing” is becoming increasingly popular. With the help of this method, the desire to have children can be created in ice. In the process, egg cells are removed from the woman and frozen. Years later, they can be thawed again, fertilized in the laboratory and used for women. A woman from Argentina has also fulfilled her desire to have children with this method. With an egg cell that had been frozen for 14 years.
Method for cancer patients
The method was originally developed for cancer patients. This enables patients to have egg cells removed before chemotherapy so that they are protected against the destructive chemicals.
In the meantime, however, more and more healthy women are using the procedure and postponing their family planning to a later date. The method has become a widespread trend in the United States. Some young women even organize “egg-freezing parties” there.
Freeze eggs for a long time
The then 25-year-old Mónica Coronel from Argentina also decided in 1999 to freeze six of her eggs after she had not become pregnant despite medical treatment, reports the dpa news agency.
Shortly before, the research team led by doctor Carlos Quintans at the Halitus Clinic in Buenos Aires had developed a new method for freezing eggs over a longer period of time.
In 2013 - around 14 years later - Coronel contacted the clinic again and had a fertilized egg cell inserted. She had previously given birth to a boy who was born naturally.
Egg cell in liquid nitrogen for 14 years
In 2014, the journal “Journal of Assisted Reproduction and Genetics” reported on “the birth of a healthy girl”. At that time, the experts wrote: "This case represents the longest known storage period of frozen human egg cells, which led to a live birth."
Now the Halitus Clinic commemorates the unusual case of the baby, which emerged from an egg cell that had been frozen in liquid nitrogen for 14 years.
The name of the three-year-old girl, Yanina, means "full of grace". "She fills us with joy every day and makes me forget what I had to go through to have a child," said the mother.
Since artificial insemination had never been successful after such a long time, the case was included in the Guinness Book as a world record, as was confirmed a few days ago.
German expert not surprised by record
As the dpa report states, however, Georg Döhmen from the Lower Rhine fertility center is not particularly surprised by the record. According to him, the problem-free use of frozen egg cells after such a long time is not unusual.
“The egg cells are stored in liquid nitrogen, there are no aging processes.” In the case of artificial inseminations, there is often the case that surplus fertilized egg cells are frozen and used years later when there is a renewed desire to have children.
However, the Guinness book justified awarding the world record to the Halitus Clinic by saying that a successful pregnancy after 14 years has so far been unique.
Age limit of 50 years
According to Döhmen, who is also a board member of the German Society for Reproductive Medicine (DGRM), the period of storage will play less of a role in the future. "The limitation is more the age of the woman," said the expert.
The risks of pregnancy are too high for women from a certain age. In addition, there are ethical aspects regarding the child's well-being.
The Fertiprotekt network, an association of centers from Germany, Austria and Switzerland, set an age limit of 50 years for artificial insemination. (ad)
