Assisted Hatching (AH) is a procedure used in conjunction with In Vitro Fertilization (IVF) to help embryos implant in the uterus.
Here’s how it works:
- The Zona Pellucida: Every embryo is surrounded by a protective shell called the zona pellucida. This shell is crucial for early development, but it can sometimes hinder the embryo’s ability to “hatch” and implant in the uterine lining.
- The Procedure: AH involves creating a tiny opening in the zona pellucida, most often with a laser.
AH may be considered in certain situations, such as:
- Previous Failed IVF Cycles: If previous IVF attempts were unsuccessful, AH might be explored as a potential solution.
- Thickened Zona Pellucida: In some cases, the zona pellucida may be thicker than usual, making it more difficult for the embryo to hatch naturally.
- Women 36 years of age or older. Some studies have shown higher implantation rates in this group with AH.
- When using frozen eggs or embryos as the freezing process can harden the zona pellucida.
