Laser Assisted Hatching (LAH)

Overview

For many couples undergoing fertility treatment, every step that improves the chances of a successful pregnancy matters deeply. Laser Assisted Hatching (LAH) is an advanced laboratory technique used during IVF treatment to help embryos implant more easily into the uterus.

In natural conception, an embryo must break out of its outer shell before it can attach to the uterine lining. In some cases, this outer layer may be thicker than usual, making implantation more difficult. Laser Assisted Hatching gently creates a small opening in this outer layer, helping the embryo “hatch” and increasing the chances of implantation.

At leading fertility centers such as Milann Fertility & Birthing hospital, highly skilled embryologists use precision laser technology to perform this procedure safely and accurately. For many patients, LAH IVF treatment offers renewed hope by improving the possibility of embryo implantation and pregnancy.

What is Laser Assisted Hatching (LAH)?

Laser Assisted Hatching (LAH) is an advanced IVF laboratory procedure that helps an embryo break through its protective outer shell, known as the Zona Pellucida, before implantation.

Using a highly controlled microscopic laser, embryologists create a tiny opening in this shell, allowing the embryo to hatch more easily and attach to the uterine lining.

Why is Laser Assisted Hatching Done?

• Previous IVF failure
• Thick zona pellucida (outer embryo shell)
• Advanced maternal age (above 35)
• Frozen embryo transfer cycles
• Slow embryo development

Preparation for Laser Assisted Hatching

Medical Preparation

• Previous IVF outcomes review
• Embryo quality assessment
• Patient age evaluation
• Zona pellucida thickness evaluation

Laboratory Preparation

• Microscopic imaging systems
• Precision laser equipment
• Controlled IVF laboratory environment

What is the Process of Laser Assisted Hatching?

1. Embryo Development
   Embryos are grown in the IVF laboratory after fertilization.
2. Embryo Evaluation
   Embryologists assess embryo quality and growth.
3. Laser Assisted Hatching
   A microscopic laser creates a tiny opening in the zona pellucida to help the embryo hatch.
4. Embryo Transfer
   The embryo is placed into the uterus using a thin catheter.
5. Implantation
   The embryo may hatch and attach to the uterine lining.

Results / Post Procedure

After Laser Assisted Hatching and embryo transfer, hormone support is usually continued to support implantation.

• Progesterone medications may be prescribed
• Light activity is recommended
• Stress should be minimized

A pregnancy test is done 10–14 days after embryo transfer.

What Are the Risks of Laser Assisted Hatching?

• Rare embryo damage during procedure
• Multiple pregnancy (if multiple embryos are transferred)
• Implantation failure

What You Can Expect

• Advanced laboratory embryo care
• Microscopic laser precision procedure
• Embryo transfer after procedure
• Pregnancy monitoring and follow-up

When Should You See a Fertility Specialist?

• Trying to conceive for over 12 months
• Age above 35 with 6 months of unsuccessful attempts
• Repeated IVF failure
• Irregular menstrual cycles
• Known fertility conditions

Common Signs You May Need Fertility Testing

• Irregular periods
• Ovulation issues
• Hormonal imbalance
• Recurrent miscarriage
• Conditions like PCOS or endometriosis

Frequently Asked Questions (FAQs)

1. What is Laser Assisted Hatching used for?
It helps the embryo hatch from its outer shell to improve implantation chances.

2. Is LAH painful?
No. It is performed in the lab and does not cause pain to the patient.

3. Does it guarantee pregnancy?
No. It may improve implantation chances but cannot guarantee pregnancy.

4. Who needs it?
Patients with previous IVF failure, thick embryo shells, or advanced maternal age.

5. Is it safe?
Yes, when performed by trained embryologists using precision laser systems.

6. Does it improve IVF success rates?
It may improve outcomes in selected patients.
