The egg donation process consists of four phases.
- In the first phase, ovarian hyperstimulation, donors receive a series of hormonal drugs to produce multiple mature eggs.
- During phase two, egg retrieval, mature eggs are removed from the donor through a surgical procedure.
- The next step is about fertilizing the donated eggs with the sperm of the future father.
- At the final phase, the resulting embryos are transferred to the receiving woman after a period of five days.
