Laser Assisted Hatching (LAH) is an advanced embryology technique used during IVF treatment to improve embryo implantation. In this procedure, a precise laser is used to create a small opening or thinning in the outer shell of the embryo (zona pellucida), helping the embryo to hatch and implant more easily into the uterine lining.
During natural conception, embryos hatch on their own before implantation. However, in certain cases, the zona pellucida becomes thick or hardened, reducing implantation potential. Laser Assisted Hatching helps overcome this barrier and enhances pregnancy chances in selected patients.
Who can benefit from Laser Assisted Hatching?
Fertility specialists may recommend LAH in the following situations:
Repeated IVF Failure
Patients with multiple failed IVF cycles may benefit from improved implantation potential with LAH.
Advanced Maternal Age
Women above 35 years often have embryos with thicker zona pellucida, making hatching more difficult.
Frozen Embryo Transfer (FET)
Frozen-thawed embryos may develop hardened outer shells, where LAH can improve implantation rates.
Thick Zona Pellucida
Embryos identified with a thick zona pellucida during lab assessment are ideal candidates for LAH.
Step-by-step Laser Assisted Hatching procedure
Laser Assisted Hatching is a quick, safe, and highly controlled laboratory procedure.
Embryo Assessment
Embryologists evaluate embryo quality and zona thickness under high-resolution microscopes.
Precision Laser Application
A focused laser beam creates a microscopic opening in the zona pellucida without damaging the embryo.
Embryo Transfer
The assisted embryo is transferred into the uterus under ultrasound guidance.
Success rates & expert embryology care
Laser Assisted Hatching does not create embryos but enhances implantation potential. In selected patients, LAH may improve pregnancy rates by 10–15%, especially in cases of repeated IVF failure or frozen embryo transfers.
Advanced Laser Technology
Highly precise, computer-controlled lasers ensure safety and accuracy.
Expert Embryologists
Procedures are performed by experienced embryology specialists.
Individualized Decision Making
LAH is recommended only when clinically beneficial for the patient.
