What are the principles in Israeli law behind the use of eggs or sperm that are not from the intended parents when a surrogate mother is used to help a childless couple become parents?

Answers

Firstly, the child cannot be created using an egg from the surrogate mother, whose role is to offer the services of her womb during pregnancy. Either the egg or the sperm must be from the intended parents. For example, the intended mother can supply the egg, in which case the sperm must come from the intended father, or a donor. Alternatively, the intended father can supply the sperm, in which case the egg must come from the intended mother, or be donated.
