There are many types of egg donations. One may use a known person, like a friend or family member to undergo IVF on her behalf. The donor’s eggs are fertilized with the partner’s sperm and the embryo transferred to the intended mother. A couple interested in more privacy may choose an anonymous egg donor through an agency. Others may prefer the cost saving appeal of purchasing frozen eggs from an egg bank. The donors are anonymous (sometimes with pictures provided) but are tested extensively for genetic and infectious diseases.
