Laser-Assisted Hatching
Advanced technique to improve embryo implantation rates
How It Works
Before implantation, an embryo must hatch from its outer shell (the zona pellucida). Laser-assisted hatching uses a precise infrared laser to create a small opening in the shell, helping the embryo hatch and implant into the uterine lining more easily. The entire procedure is performed by an embryologist under a microscope and takes less than 10 minutes.
Who May Benefit
- Women over 35
- Multiple failed IVF cycles
- Embryos with thick or irregular zona pellucida
- Elevated FSH (diminished ovarian reserve)
- Frozen-thawed embryo transfers (FET)
- Poor-quality embryos
When Is Laser Hatching Applied?
Day before transfer
Typically performed the day before embryo transfer, giving the embryo time to recover and prepare for implantation
Day 5-6 blastocyst
Laser hatching is most effective on day 5-6 blastocysts when the embryo is fully developed
Frozen-thawed embryo
Frozen embryos may have a slightly hardened zona after thawing — laser hatching helps overcome this
Frequently Asked Questions
Is laser-assisted hatching safe? Can it damage the embryo?
Laser-assisted hatching is a clinically established, safe technique used for over 20 years. The infrared laser creates only a tiny opening in the zona pellucida (the outer shell) — it never contacts or damages embryo cells. Extensive research shows no difference in congenital anomaly rates between children born from laser-hatched embryos and those who did not receive hatching. The procedure is performed by licensed embryologists under strict quality control.
Does every IVF cycle require laser-assisted hatching?
Not every patient needs it. Laser hatching is an elective adjunct that physicians typically recommend in specific circumstances: multiple failed transfers, embryos with thick or irregular zona pellucida, older patients (generally ≥ 37), and frozen-thawed embryo transfers. For first-time IVF patients who are young with good-quality embryos, laser hatching is usually not necessary. Your physician will make a personalized recommendation based on your embryo evaluation results.
How much does laser-assisted hatching cost?
Laser hatching is typically an add-on to the IVF cycle, with an additional cost of approximately $500–$1,500 depending on the clinic. While modest relative to overall IVF costs, it is best chosen only when there is a clear medical indication rather than routinely. Confirm exact pricing with your HRC coordinator at your first consultation.
