Egg donation can create a family while also building relationships that may remain relevant long after fertility treatment ends. A medical concern involving a donor-conceived child may raise questions about how those relationships should be managed. A diagnosis may leave parents wondering whether they can contact their egg donor for additional family or genetic health information.
In California, the answer depends heavily on the original egg donation arrangement, including whether the donor was known or unidentified and what the parties agreed to before the donation occurred. Medical necessity may provide a strong reason to seek information, but it does not automatically erase privacy boundaries established between the parties.
An egg donation agreement may determine how contact occurs
A properly prepared egg donation agreement can address more than compensation and parental rights. It may establish whether future communication is permitted and how requests for updated medical information should be handled.
For example, an agreement might require communication to go through the fertility clinic, egg donation agency or another designated intermediary rather than allowing parents to contact the donor directly.
This difference becomes important when a child develops a condition that may have a hereditary component. The parents may want information about newly diagnosed illnesses within the donor’s biological family, changes in the donor’s health or genetic conditions that were unknown when the initial screening occurred.
Therefore, parents should review the agreement before attempting direct contact. Circumventing an agreed communication process could create unnecessary privacy and contractual concerns.
For parents facing a child’s medical diagnosis, reviewing an existing donation agreement can help clarify the appropriate next steps. A legal professional familiar with assisted reproduction agreements can examine the contract and explain the available options. If communication with the donor is appropriate, it can then occur in a manner that respects a child’s medical needs and the boundaries established during the donation process.
