Laser Assisted Hatching (LAH) is an advanced IVF technique that uses a precise laser beam to create a small opening in the outer shell (zona pellucida) of an embryo. This helps the embryo hatch more easily and attach to the lining of the uterus, increasing the chance of successful implantation.
In natural conception, the embryo hatches on its own before implanting. However, in some IVF cases, especially where the outer shell is thick or hardened, this natural process may be disrupted. LAH helps facilitate this critical step, supporting a successful pregnancy.
At Zemya IVF & Fertility Clinics, we offer Laser Assisted Hatching (LAH) as part of our advanced IVF services to help improve embryo implantation and pregnancy outcomes.
Our fertility specialists may recommend LAH at Zemya IVF & Fertility Clinics when there is a concern about implantation failure due to embryo hatching issues. We use state-of-the-art laser technology, handled by experienced embryologists in our advanced embryology lab.
LAH is especially considered for:
LAH aims to improve implantation potential, particularly when embryo hatching is suspected to be a limiting factor. Our team assesses each IVF case carefully to determine whether LAH will provide additional benefits.
Embryos are cultured in the lab up to day 3 or day 5 (blastocyst stage). The embryologist assesses their quality and development.
Each embryo is carefully placed under the laser-equipped microscope. The embryologist ensures the embryo is correctly oriented for safe hatching.
Using a computer-controlled laser, a small opening (usually around 10–20 microns wide) is made in the zona pellucida.
After hatching is complete, the embryo is transferred into the uterus using a thin catheter under ultrasound guidance—just like in a standard embryo transfer. LAH does not require anesthesia, and the patient is discharged shortly after the procedure.

Yes. In selected patients, especially those with a history of implantation failure or older age, LAH can improve implantation and pregnancy rates by helping embryos hatch more efficiently.
Yes. The procedure uses a non-contact, precision laser that creates a small hole in the shell without damaging the embryo. At Zemya IVF & Fertility Clinics, LAH is done by trained embryologists in a controlled lab environment.
LAH is usually performed on day 3 or day 5 embryos, and is especially useful for frozen-thawed embryos, which tend to have harder outer shells. However, it is only done when medically indicated.
No. The procedure is performed on the embryo in the lab. The embryo transfer, which follows LAH, is painless and non-surgical.
Not directly. However, if more than one embryo is transferred and both implant successfully, twin pregnancy may occur. LAH does not affect the number of embryos transferred unless combined with single embryo transfer planning.
Your fertility specialist will assess your age, embryo quality, IVF history, and lab findings to determine whether LAH is appropriate for you.
