Laser Assisted Hatching (LAH)

Laser Assisted Hatching (LAH) is a microsurgical IVF adjunct that can improve embryo implantation in selected patients. At Conceive Fertility IVF in Bangalore, Dr. Anne Marie offers evidence-based LAH as part of individualized treatment plans.

Laser Assisted Hatching (often abbreviated LAH) uses a precise laser to thin or make a small opening in the embryo's outer shell (the zona pellucida). This helps the embryo escape the shell and attach to the uterine lining during implantation.

How the LAH Procedure Works?

LAH is performed in the IVF laboratory by an embryologist using a focused infrared laser under the microscope. Key steps include:

Selection of the embryo to be hatched (usually day 3 or day 5/6 embryos depending on lab protocol).

Stabilization of the embryo in a micro-drop of culture medium under oil to maintain temperature and pH.

Application of the laser to thin or create a small opening in the zona pellucida; the action is measured in milliseconds and under strict safety controls.

Return of the embryo to culture or immediate transfer, based on the treatment plan (fresh transfer or frozen embryo transfer — FET).

Who May Benefit from LAH?

LAH is not routine for every IVF cycle. Candidates who may benefit include:

  • Women aged over 35 years, where zona hardening is more common.
  • Patients with previous unsuccessful IVF cycles despite good-quality embryos.
  • Couples using frozen embryos (FET), where cryopreservation can thicken the zona.
  • Embryos with a thick or irregular zona pellucida as assessed by the embryologist.
  • Certain cases of unexplained implantation failure after thorough evaluation.

Our offer assistance with activities such as:

Comprehensive Fertility Assessment

Detailed review of your medical history, previous IVF outcomes, age, and embryo quality to determine if LAH is suitable.

Advanced Embryology Laboratory

The procedure is performed using precision laser technology by experienced embryologists in a controlled IVF laboratory to ensure embryo safety.

Personalized Treatment Planning

Laser-Assisted Hatching is recommended only for patients who are most likely to benefit from the technique based on clinical indications.

Embryo Quality Evaluation

Each embryo is carefully assessed before the procedure to determine whether assisted hatching may improve implantation potential.

Frequently Asked Questions

1. Does LAH increase the chance of pregnancy for everyone?

No. LAH is beneficial in selected situations (older patients, frozen embryos, prior implantation failures). It is not recommended as a universal addition for all IVF cycles.

When done by trained embryologists using validated laser systems, LAH is considered safe with a low complication rate. Conceive Fertility IVF follows strict laboratory protocols to protect embryo viability.

Costs vary by clinic and whether LAH is bundled with IVF or FET. Conceive Fertility IVF provides transparent pricing during consultation — please contact the clinic for a detailed estimate.

Not always, but cryopreservation can harden the zona pellucida. Embryologists evaluate thawed embryos and recommend LAH if it appears beneficial.

There is no separate patient preparation for LAH itself. Follow your IVF or FET cycle instructions provided by Dr. Anne Marie and the clinic staff regarding medications, bed rest, and follow-up.

LAH itself does not increase the risk of congenital abnormalities. Multiple pregnancy risk depends primarily on the number of embryos transferred. Single embryo transfer policies combined with LAH are commonly used to reduce multiple pregnancy risk while optimizing implantation.
