Multiple embryos can emerge from a successful in vitro fertilization (IVF) session, and some people choose to freeze the additional embryos for future family formation.

Patients who undergo preimplantation genetic diagnosis (PGD) usually freeze their embryos following the test because the findings can take up to a week to arrive.

Freezing embryos is another method for preserving future fertility. Some people opt for this operation because they are having hormone therapy, cancer treatment, gender affirmation surgery, or another medical procedure that will affect their fertility.

In some cases, your doctor may propose freezing your embryos to reduce the risk of ovarian hyperstimulation syndrome, which can become more severe after pregnancy. It might also be suggested to help boost the chances of getting pregnant.
