(a) If a marriage is dissolved before placement of eggs, sperm or embryos, the former spouse is not a parent of the resulting child unless the former spouse consented in a record that if assisted reproduction were to occur after a divorce, the former spouse would be a parent of the child.

(b) The consent of a woman or a man to assisted reproduction may be withdrawn by that individual in a record at any time before placement of eggs, sperm or embryos. An individual who withdraws consent under this section is not a parent of the resulting child.
