'Three-parent' baby born in Ukraine using new technique

• https://www.yahoo.com,

The boy was conceived using DNA from his mother and father but also from an egg donor in a technique called pronuclear transfer, said Valeriy Zukin, director of the Nadiya private fertility clinic in Kiev.

"It is the first delivery (using) pronuclear transfer all over the world," Zukin told AFP.

The clinic said in a statement that the 34-year-old mother gave birth to a healthy boy on January 5 after trying for a baby for more than 15 years and undergoing several failed rounds of IVF

This became possible after the woman's eggs were fertilised with her partner's sperm, but then their nuclei were transferred to a donor's egg which had previously been stripped of its own nucleus.

As a result of the procedure, the egg was almost entirely made up of genetic material from the couple, plus a very small amount (some 0.15 percent) of the female donor's DNA.

Zukin said he hopes the pronuclear transfer technique could help other women whose embryos stop developing at a very early stage of development during cycles of IVF.
