A healthy baby girl weighing 3.3kg was born from an embryo frozen for more than a decade.

(Dan Tri) - On August 27, the Central Maternity Hospital informed about the case of a pregnant woman giving birth to a healthy baby, from an embryo frozen in 2014.

Prof. Dr. Nguyen Duy Anh - Director of the Central Maternity Hospital said that after the surgery on August 22, both mother and child are healthy.

Previously, in 2014, Ms. VA (born 1988, Hanoi ), performed in vitro fertilization at the National Center for Reproductive Support and gave birth to her first baby boy.

The remaining embryos were deposited at the center. At the time of deposit, the doctor informed that the embryos would be safely preserved for 5 years, 10 years or more.

Earlier this year, Ms. VA returned to the center with the hope of having a second child. The archived records showed that all embryos were still intact, with full information and quality as the first day they were sent to the archive room.

Ms. VA said that when she saw the intact embryo, she was both excited and touched, but also very worried because the embryo had been stored for 11 years.

When the doctor explained that the embryo was healthy and the quality was maintained, Ms. VA was determined to place the embryo to give birth.

During the first embryo transfer after 11 years, Ms. VA became pregnant. This special pregnancy was closely monitored by Professor Nguyen Duy Anh, because he understood that this was not just a normal pregnancy management case, but a vivid demonstration of the power of modern embryo preservation technology.

"The embryo was frozen for 11 years in a freezer, after being removed, transferred into the mother's uterus on the first successful attempt. The patient was initially very worried, thinking that after all these years the embryo might have been damaged and unusable, and creating a new embryo at this age would be very difficult.

But in reality, embryos stored properly in the freezer of the National Center for Reproductive Support - Central Obstetrics Hospital still ensure quality after more than a decade. We used only one embryo, transferred it successfully and the results were as expected," said Professor Anh.

On the morning of August 22, a 3.3kg baby girl cried loudly in the delivery room, extremely healthy and rosy.

Professor Anh said that the National Center for Reproductive Support is currently storing hundreds of thousands of embryos using advanced technology and machinery according to international standards, ensuring safety, helping mothers, even at an older age, to get pregnant with embryos stored when they were young. The survival rate of embryos after thawing is 99-100%.
