Understand Laser Assisted Hatching (LAH)- Improve Your IVF Success Rate
The journey of infertility treatment can be daunting and emotional for couples. At Newlife Fertility Centre, Siliguri, we empathise with such patients and provide customized treatment options. Laser Assisted Hatching (LAH) can be the advanced course of treatment if you have suffered an uncountable number of failed cycles of In-Vitro Fertilisation (IVF) or are using frozen embryos. This can be the advanced support that you need for a successful pregnancy.
A micromanipulation technique using a state-of-the-art method that is designed to guide the embryo to naturally go through the process of 'hatching'. The zona pellucida, or the outer layer of the embryo, is weakened, or a tiny hole is created for easy implantation of the embryo.

What is Laser Assisted Hatching?
For a successful implantation, the embryo must hatch out from the shell, which is called the zona pellucida, which can sometimes be unnaturally thick or hard, especially in cases when:
- Frozen embryos
- Poor embryo development
- Previous failed IVF attempts
- Women over 35 years of age
A small opening is created to weaken the shell through precise laser use, by the technique of Laser Assisted Hatching. This assists the embryo to get implanted and hatch safely.
When is LAH Recommended?
For every IVF case, LAH is not recommended. The following conditions demand this treatment:
- Advanced maternal age (35+)
- Embryos with thick zona pellucida
- Use of frozen-thawed embryos
- Previous failed IVF or ICSI attempts
- Embryos showing slow growth or poor quality
- Cases where Preimplantation Genetic Testing (PGT) is done
LAH will only be advised to you based on your fertility health and medical history by your fertility specialists.
How is Laser Assisted Hatching Done?
A team of skilled embryologists at Newlife Fertility Centre carries out the LAH treatment with precision and expert care. Advanced laser micromanipulation systems are used, and the steps are broken down below:
- Embryo Stabilization: The embryo is gently held in place under a high-resolution microscope using a holding pipette.
- Laser Application: A finely controlled laser pulse is used to make a tiny opening or thin out a section of the zona pellucida (outer shell).
- Post-Hatching Handling: Once the procedure is complete, the embryo is cultured for a short time and then transferred to the uterus during the IVF cycle.
To make sure that the embryo viability is maintained, this procedure is performed in a sanitised, temperature-controlled laboratory environment. A painless and quick procedure, it just takes a few seconds per embryo.

Benefits of Laser Assisted Hatching
- Increased Implantation Chances: Helps embryos hatch and attach more easily to the uterine lining, improving success rates.
- Boosts Pregnancy Rates: Especially beneficial in IVF cases with previous failures, poor embryo quality, or advanced maternal age.
- Enhances Frozen Embryo Transfer Outcomes: Thawed embryos with hardened shells benefit significantly from assisted hatching.
- Safe & Minimally Invasive: The laser creates a precise opening without damaging the embryo, making it a low-risk procedure.
- Expertly Performed: Conducted by skilled embryologists using high-end laser technology in a controlled lab environment.
LAH and IVF: A Powerful Combination
Though it does not assure the chances of pregnancy, LAH sure provides notable advantages when used correctly. This assists the embryo to implant successfully, especially for couples who have experienced failure in the past through IVF procedures.

Frequantly Asked Questions
Will the embryo be safe in Laser Assisted Hatching?
Yes. There are minimal risks associated with LAH, which is considered to be safe to the embryo when performed by experienced specialists and embryologists.
Can LAH increase my chances of pregnancy?
It does not guarantee pregnancy but has been shown to increase implantation rates in selected patients.
Is LAH done on all embryos?
No. Upon close study by the specialists, LAH may be advised for particular cases of IVF by clinical recommendation.
Will I need LAH in every IVF cycle?
Not necessarily. It depends on factors such as embryo quality, age, and IVF history.
