3 parents: baby is born with DNA from 2 mothers and 1 father

Having children is a common desire of many people.

However, married or single, some find it difficult to invest in maternity or biological paternity due to infertility or other problems.

So, in some cases, the option is called in vitro fertilization , which basically promotes the fertilization of an egg and a sperm in the laboratory.

The technique is not so recent, since the first baby conceived by in vitro fertilization was born in 1978. Since then, it is estimated that about 8 million births were the result of a procedure performed in the laboratory.

Now a recent in vitro fertilization experiment, carried out at the Institute of Life in Greece, called attention to the result: a baby with 3 DNAs.

Two moms and a dad

The case in Greece gave rise to a healthy baby who will be able to count on two mothers and a father, that is, the egg donor, the mother (supplier of genetic material) and the father.

The scientists managed to make the couple overcome the problems of infertility, using a method slightly inverted to in vitro fertilization .

It is the transfer of the maternal spindle, a procedure in which the egg of a female donor is filled with genetic material from the mother and is then fertilized through another method, called assisted reproduction.

According to the researchers, this was only possible due to the action of the donor’s mitochondria (structures that produce energy and have their own genetic material).

Since mitochondria contain their own genetic material, they were removed from the first mother and transferred to the eggs of the second mother.

Then, the egg was fertilized with the father’s sperm, using the in vitro technique and returned to the first mother’s uterus, to continue the pregnancy.

The baby’s first mother, aged 32, had already undergone 4 rounds of IVF , but to no avail. And only with the new method tested, it was possible for her to become pregnant.

Still according to the authors of the study, the finding suggests that the technique used can be used for infertility treatments or pregnancy difficulties.

New treatments and techniques help people who wish to experience maternity or biological paternity.

So it is important that new discoveries happen to allow infertility problems to decrease as soon as possible.
