Improving Embryo Implantation Success
For couples looking for the best IVF centre in Khan Market, finding advanced embryology solutions is key. An embryo is surrounded by a protective outer shell called the zona pellucida. To implant successfully into the uterine wall, the embryo must hatch out of this shell. However, in older women or those with frozen embryos, this shell can be abnormally thick or hard, preventing natural hatching. At Pravi IVF, we use Laser-Assisted Hatching (LAH) to create a tiny opening in the outer shell before transfer, helping the embryo hatch and implant successfully. Our clinic on Ring Road is conveniently located for Khan Market patients. To check directions, visit our Best IVF Centre in Khan Market page.
How Laser-Assisted Hatching Works
Under a high-powered microscope in our Class-100 cleanroom lab, our embryologist uses a computer-guided laser to deliver a micro-pulse energy beam to the outer shell. This thins a tiny section of the shell without touching the embryo cells. According to clinical consensus bulletins from the American Society for Reproductive Medicine (ASRM), laser hatching improves implantation rates in cases of advanced maternal age and repeated IVF failure. We combine this technique with our automated Electronic Witness System to ensure complete embryo safety.

Dr. Monica and our embryology team utilize laser hatching to support older maternal age and recurrent failure cases. We have shared a video of laser hatching under the microscope on YouTube (search "Pravi IVF Laser Assisted Hatching Demonstration") and share implantation success tips on Instagram (@PraviIVF).

Frequently Asked Questions (FAQs)
- What is Laser-Assisted Hatching (LAH)?
It is an advanced laboratory procedure that uses a precision laser to create a microscopic opening in the embryo protective outer shell to facilitate hatching and implantation. - Does the laser harm the embryo?
No. The laser energy is highly focused and applied only to the non-cellular outer shell (zona pellucida), leaving the internal cells untouched. - Who should consider laser-assisted hatching?
It is recommended for women over 37, couples with previous failed IVF cycles, or when transferring frozen embryos that have hardened shells. - Does laser hatching increase the chance of twins?
There is a very slight increase in the rate of identical twins due to the opening, but overall multiple pregnancy risks are managed by single embryo transfers. - Is this procedure performed on fresh or frozen embryos?
It can be performed on both, but it is highly beneficial for vitrified-thawed embryos because freezing can sometimes cause the shell to harden.
