What is Laser-Assisted Hatching?
In natural conception, embryos must "hatch" from their shell to successfully implant in the uterus. Sometimes, embryos created through IVF have a thicker or harder zona pellucida, making hatching difficult. Laser-Assisted Hatching (LAH) uses a highly focused laser beam to gently thin or open the zona, increasing the chances of successful implantation.
This technique is especially useful in older women, patients with repeated IVF failures, or embryos with slow development.
