The success of IVF does not depend on fertilized eggs only. The fertilized egg or embryo
should be implanted on the uterus wall for a successful pregnancy. Failure of the
embryos to hatch and implant may result in IVF failure.
Your fertility doctor may
use modern-day technology laser-assisted hatching along with IVF to increase the chances
of an embryo’s successful implantation.
What is Laser-Assisted Hatching?
The doctor will keep your fertilized eggs in the laboratory for two to five days during
the IVF procedure. During this period, the eggs divide and become an embryo. Your
fertility doctor will place the healthy embryo into your uterus. A protective layer
called zona pellucida surrounds the embryo. This layer should break out naturally for
successful implantation. Sometimes, this outer layer hardens and does not break. It may
cause IVF failure.
In laser-assisted hatching, your embryologist creates a small crack in the embryo,
before placing the embryo in your uterus. It helps in breaking the outer protective
layer leading to successful implantation.
What are the indications of laser-assisted hatching?
Your doctor may recommend after laser-assisted hatching in the following conditions:
- History of the failure of IVF cycles
- Increased FSH level
- Poor quality of your embryo
- If your age is more than 38
- Infertility due to unexplained reasons
Your doctor may perform an LAH procedure on the 3rd day after the IVF cycle. Your doctor
may use a specialized laser to create a small crack in zona-pellucida when the embryo is
still in the laboratory.
Advantages of LAH
Accuracy: Laser-assisted hatching is more accurate when compared with other assisted
Safety: LAH procedure does not require any manual handling of your embryo, ensuring
the safety of the embryo. LAH can boost the success rate of your pregnancy.
Are there any risks associated with LAH?
LAH involves a similar risk as in IVF or ICSI procedures. Since it involves interference
with the natural hatching process; therefore there are some risks. Some of the risks
associated with LAH
Potential injury to the embryo leading to failed hatching
2.Multiple pregnancies: LAH procedure can increase the risk of multiple pregnancies.
LAH may not be a mandatory procedure needed for pregnancy. But if the embryo fails to
implant, LAH may be an option. LAH procedure can increase the chances of positive
pregnancy. At BabyScience IVF Clinics, our experienced fertility doctors may use
laser-assisted hatching to overcome the problem of thick-shelled embryos. LAH may
increase the chances of implantation and thus pregnancy
