If you are in the country or having treatment, a donation treatment, in a country that the doctor needs to select the donor for you or must according to regulations, then what they usually do is take a full characteristics of both intended parents and then try and match to the phenotypic characteristics of the donor as much as possible, for example, hair colour, eye colour, skin tone and the body build. These will, of course, be quite subjective and therefore there is an element that may or may not lead to the same characteristics you would expect in the baby.
Can facial resemblance be something more than subjective? The answer is yes. We talk about facial resemblance when we see that a child and you decide that there is a resemblance to one of their parents. Facial resemblance nowadays is more than subjective because there are tools that are developed to measure the resemblance. These tools, like Fenomatch, are based on biometrics and they measure the facial resemblance and give you a score. Fenomatch, in this case, uses AI, to measure more than 12,000 facial biometrics and we help doctors and embryologists to decide on the best egg/sperm donor for the patient. So, here, we can be more than subjective and based the donor selection decision on scientific arguments.
