Supporting Embryo Implantation with Precision Technology
Laser Assisted Hatching (LAH) is an advanced micromanipulation technique used during IVF to help embryos implant more effectively into the uterine lining. This method involves using a precise laser to create a small opening in the zona pellucida—the outer shell of the embryo—to assist the embryo in “hatching” and increasing the chances of a successful pregnancy.
At IshwaIVF, we use state-of-the-art laser systems and skilled embryologists to perform LAH with utmost accuracy, especially in cases where previous IVF cycles have failed or when implantation is a challenge.
What is the Zona Pellucida?
The zona pellucida is a protective outer layer surrounding the embryo. For a successful pregnancy, the embryo must naturally break out (or “hatch”) from this layer and attach to the uterine wall. However, in some cases, especially with frozen or older embryos, this hatching process may be difficult or delayed.
Laser Assisted Hatching gently weakens or thins the zona to aid the natural hatching process, without damaging the embryo.
When is LAH Recommended?
- Women above 35 years of age
- Previous IVF failures
- Embryos with thick or hard zona pellucida
- Frozen-thawed embryos
- Embryos undergoing Preimplantation Genetic Testing (PGT)
- Couples with unexplained infertility
Benefits of Laser Assisted Hatching
- Improves implantation rate in selected patients
- Safe and precise—uses laser for accuracy and reduces human error
- Quick and controlled—takes only a few seconds under microscope
- Minimally invasive—no physical or chemical damage to the embryo
- Can lead to better IVF outcomes, especially in difficult or high-risk cases
How the Process Works at IshwaIVF
- Embryo Development
Embryos are developed in the lab up to Day 3 or Day 5 (blastocyst stage). - LAH Procedure
Using a microlaser under a high-resolution microscope, a tiny hole or thinning is made in the zona pellucida. - Embryo Transfer
The treated embryo is transferred to the uterus for natural implantation. - Follow-up and Support
Our team continues monitoring with early pregnancy support and care.
Frequently Asked Questions (FAQs)
1. Is laser hatching safe for the embryo?
Yes, LAH is considered safe when performed by experienced embryologists using controlled laser pulses. It avoids physical touching or chemical exposure.
2. Does LAH guarantee pregnancy?
While it increases the chances of implantation, especially in selected patients, it does not guarantee pregnancy. It is a supportive technique.
3. Is LAH performed in every IVF cycle?
No. LAH is used in specific cases based on patient history, embryo quality, and the doctor’s recommendation.
4. Does LAH affect the baby’s health?
No studies have shown any negative impact on the health of babies born through LAH. It’s a safe technique used worldwide in IVF labs.
