The fertility treatment with donor eggs is the treatment with the highest success rates of all regardless of the couple’s or single’s infertility problem. That is because the age of the eggs plays the biggest role in the success rates of any fertility treatment and is not curable.
The genetic background of a baby created with donor eggs will be determined by the genes of the egg and the sperm that have been used to create it. In case the recipient of donor eggs will use her partner’s sperm for the treatment then there is a high probability for the baby to look like his father. However, the manifestation of the genetic information on a human being is very complicated and there are many evidence-based ways that show that the intended mother can affect how the baby will look like.
Just because the baby did not receive any genes from the intended mother it does not mean that it will not look like his mother. How is this possible?
The baby will pass the first 9 months of his life in the uterus of the egg recipient. This organ during the pregnancy is normally filled with embryonic fluid which contains micro RNAs, which are DNA molecules that facilitate the communication between the mother and the baby during pregnancy. These micro RNAs do play a role not only in the physical but also in the personality traits of the baby. You will be surprised how many mothers that have used donor eggs to conceive, call us every day announcing how excited they are by how their child looks like them or someone from their family. Let’s not forget that the child also as soon as it is delivered by the intended mother recognizes immediately her smell and looks for her breast in order to receive milk, a bond created automatically by the newborn with his mother.
