Nuclear transfer — is a unique approach to the treatment of infertility: it gives hope to give birth to a genetically native child to couples, to whom the reproductive medicine previously could only offer donor eggs.
For today, 2 types of nuclear transfers have been successfully implemented — at the stage of the spindle (John Zang, 2016) and the pronuclear transfer (clinic Nadiya, 2017).
The third way — the transfer of genetic material before the time of full maturation — is in the active stage of the scientific experiment and we hope in the near future to be able to help many women at the age above 42 years old and the birth of a healthy native child without donation of eggs.

On September 17, 2018, an interview was conducted on the channel UA:Pershy with the participation of Executive Director of “Darwin Life-Nadiya” Dmytro Mykytenko, MD, D.Sc. and Embryologist of the Clinic of reproductive medicine “Nadiya” Pavlo Mazur. The interviewers discussed the top theme about the newest method of infertility treatment - Nuclear transfer.

This is the first baby to be born using a particular “3-parent-baby” technique to treat infertility.
The girl was born on 5 January in a fertility clinic in Kiev, Ukraine. “With the help of this method, a 34-year-old woman who had suffered from infertility for more than 15 years gave birth to a healthy baby that’s genetically her own,” said a statement from the Nadiya clinic
Thousands of British couples who are struggling to have children could benefit from a new “three-parent” IVF technique that has enabled a previously infertile woman to give birth. Doctors announced yesterday that a healthy boy had been delivered after the world’s first operation of its kind, but some scientists warned that the treatment could be unsafe and could give women false hope.

Doctors in Kiev used a method called pronuclear transfer in what is a world first. It is, however, not the first child born with DNA from three parents. The baby girl, born on 5 January, is thought to be the world's second "modern three-parent baby" - another child was created using a slightly different method in Mexico last year.

Darwin Life-Nadiya is a united team of US and Ukrainian scientists who have combined experience in molecular genetics, embryology and human reproduction to develop the newest methods for achieving the pregnancy with a healthy baby in women with the high risk of mitochondrial pathology in their offspring, as well as in complicated cases of infertility forms with high genetic risk. Experimental technology of the nuclear transfer allows:
