What Is Laser-Assisted Hatching?
In IVF treatment, not only the quality of the egg and sperm but also the successful implantation of the embryo into the uterus is one of the most critical factors determining success.
Laser-assisted hatching is an advanced laboratory technique designed to facilitate embryo implantation by performing a precise, micron-level procedure on the embryo’s outer membrane, known as the zona pellucida.
The zona pellucida is a natural protective layer that normally thins and opens spontaneously before implantation. However, in some embryos, this process may be insufficient. In such cases, a small opening is created in the zona pellucida using laser technology, allowing the embryo to hatch more easily and attach to the uterine wall.
At FertiJin IVF Center, this procedure is performed safely using a non-contact laser micro-drilling method, ensuring the embryo is not physically touched or damaged.
Laser-assisted hatching helps improve implantation potential and may increase the likelihood of achieving a healthy pregnancy.

What Is Assisted Hatching?
Assisted hatching is a laboratory procedure in which the outer membrane of the embryo (zona pellucida) is carefully weakened, or a microscopic opening is created.
The goal is to increase the chances of implantation by helping the embryo hatch and attach more easily to the uterine lining.
This procedure is typically performed between day 2 and day 5 of embryo development and is especially recommended in the following cases:
- Maternal age over 35
- History of multiple failed IVF attempts
- Embryos with a thick zona pellucida
- Slow-developing embryos
Thanks to this method, many couples have successfully achieved pregnancy even after multiple IVF attempts.
How Is Laser-Assisted Hatching Performed?
Laser-assisted hatching is a highly precise microscopic laboratory procedure.
Steps of the procedure:
- The embryo is monitored in the laboratory until it reaches the appropriate developmental stage.
- Under a microscope, a laser device is precisely focused on a specific area of the zona pellucida.
- A micron-sized opening is created in the zona pellucida.
- This helps the embryo hatch more easily and improves its ability to implant in the uterine wall.
There is no physical contact with the embryo during the procedure. Thanks to non-contact laser technology, the process is safe, painless, and quick.
After the procedure, embryos are prepared for transfer and placed into the uterus.
Who Is Laser-Assisted Hatching Suitable For?
This technique is especially recommended for:
- Women aged 35 and older
- Couples with repeated IVF failures
- Embryos with a thick zona pellucida
- Patients with previous unsuccessful ICSI or IVF cycles
It may also be beneficial for younger women when a thick zona pellucida is observed.
At FertiJin IVF Center, laser-assisted hatching has contributed to successful pregnancies even after multiple IVF attempts.
💡 Laser-assisted hatching is one of the most advanced embryo support technologies offered at FertiJin IVF Center in Istanbul.
Advantages of Laser-Assisted Hatching
- Increases the chance of embryo implantation
- Offers new hope after unsuccessful IVF cycles
- May improve the likelihood of a healthy pregnancy
- Particularly beneficial in advanced maternal age or thick zona pellucida cases
- Non-contact laser technology does not harm the embryo
Frequently Asked Questions (FAQ)
Does laser-assisted hatching harm the embryo?
No. The embryo is not directly touched. The laser creates a highly precise, micron-level opening without causing damage.
Who is recommended for laser-assisted hatching?
It is recommended for women over 35, those with multiple failed IVF attempts, or embryos with a thick zona pellucida.
Does laser-assisted hatching increase pregnancy rates?
At FertiJin IVF Center, this technique has been shown to significantly improve implantation and pregnancy rates in selected patients.
