Laser Assisted Hatching (LAH) in Pune
Advanced embryo micromanipulation technique designed to support implantation in selected IVF cases at Embryonic Fertility & IVF Centre.
What is Laser Assisted Hatching?
Laser Assisted Hatching (LAH) is a laboratory procedure performed during an IVF cycle to help the embryo break through its outer shell (zona pellucida). A precise laser beam creates a small opening in the outer layer, which may assist the embryo in implanting into the uterine lining.
This technique is often considered in advanced reproductive protocols alongside procedures such as Blastocyst Transfer and Frozen Embryo Transfer (FET).
Why is Laser Assisted Hatching Recommended?
- Repeated IVF implantation failure
- Thickened zona pellucida
- Advanced maternal age
- Previously frozen embryos
- Suboptimal embryo hatching in prior cycles
Laser technology allows greater precision compared to older mechanical methods, improving procedural safety within modern embryology laboratories.
How the Procedure Works
After fertilization during an IVF treatment cycle, embryos are cultured in a controlled laboratory environment. Before embryo transfer, a specialized embryologist uses a laser system to thin or open a small section of the zona pellucida. The embryo is then transferred to the uterus for implantation.
Is Laser Assisted Hatching Safe?
When performed by experienced embryologists using modern laser systems, LAH is considered safe and controlled. The procedure is precise and minimally invasive, ensuring embryo integrity during manipulation.
Frequently Asked Questions
Does laser assisted hatching improve pregnancy rates?
In selected cases such as repeated implantation failure, LAH may support improved implantation potential.
Is laser assisted hatching necessary in all IVF cycles?
No. LAH is recommended selectively based on patient profile and previous treatment history.
Is the embryo damaged during laser hatching?
Modern laser systems are highly precise and designed to minimize any risk to the embryo.
Is LAH used with frozen embryos?
Yes, LAH is sometimes performed before a Frozen Embryo Transfer, particularly when the zona pellucida is thickened after thawing.
Who decides if LAH is required?
The embryology team evaluates embryo quality, patient history, and implantation patterns before recommending LAH.
