Artificial insemination succeeds by hatching technique

In vitro fertilization center of Van Hanh Hospital (Ho Chi Minh City) has successfully applied in vitro fertilized embryo transfer thanks to hatching support technique.

On June 25, Dr. Ho Manh Tuong said a month after being transferred to a cold-treated cryopreserved embryo, 42-year-old NMP patient was pregnant. Previously, in 8 years, she was 6 times transferred embryos in vitro fertilization by conventional methods but failed.

According to Dr. Tuong, the hatching support technique has been successfully implemented in the United States since 1989, to thin the shell around the embryo, to help the embryo escape easily from the membrane and cling to the endometrium for nesting.

This technique is particularly effective for a number of difficult cases, in which many cases fail with in vitro fertilized embryo transfer despite good embryo quality and cold embryo transfer. In the world, this technique is also widely used to increase the rate of pregnancy fertilization in vitro.

Officially implemented in vitro fertilization technique from July 2007, up to now IVF Fertilizer Center has performed more than 50 IVF cases using techniques to support hatching embryos, with pregnancy rate above 40%.
