Embryo freezing is a technique to freeze and store embryos for later use. An embryo is an egg that has been fertilized by a sperm. This process is a way to help people with fertility and reproduction

Who Might Consider Embryo Freezing?

1. Couples undergoing IVF who want to save extra embryos for future pregnancies

2. Individuals undergoing medical treatments (e.g., chemotherapy) that may affect fertility
3. People delaying pregnancy for personal or career reasons
Procedure Steps

1. Ovarian Stimulation – Hormonal medications stimulate the ovaries to produce multiple eggs.
2. Egg Retrieval – Mature eggs are collected via a minor surgical procedure.
3. Fertilization – Eggs are fertilized with sperm in a lab to form embryos.
4. Embryo Freezing (Cryopreservation) – Healthy embryos are frozen using:
    -   Slow freezing (gradual cooling)

    -   Vitrification (ultra-rapid freezing to prevent ice crystals)
5. Storage – Embryos are stored in liquid nitrogen (-196°C) for future use.

Success Rates

   -   Frozen embryo transfer (FET) success rates are similar to fresh embryo transfers.
   -   Studies suggest that frozen embryos may have better implantation rates because the uterus has time to recover from ovarian stimulation.
