Consider these cases:
1. A man donates sperm and later wishes to know his biological children
2. A woman donates an egg and then wishes to meet her child
Now let's make it more interesting. Let's say a husband and wife donated an egg and sperm which were fertilized into a zygote. This zygote was to be implanted into another woman (let's say the wife was unable to safely give birth). Now imagine that the doctor accidentally implanted the wrong zygote during this procedure. The baby will not be genetically related to the mother or father. Do they have a right to know that they are not genetically related to the baby?
"In Great Britain, when two children were born after IVF treatment, and were apparently created using the wrong sperm, their parents sued.The children have darker skin than their white parents and, according to their mother, have been subjected to ridicule and name-calling. However, a judge ruled that the case had no merit and that "the children had no legitimate expectation other than being born healthy and well."He also stated, "The presence of persons sufficiently misguided and cruel as to issue racist comments directed to these children is no basis for a conclusion that they are somehow damaged."Thus the parents will not receive remuneration for personal injury even though the wrong sperm was used."
