When is LAH considered?

LAH may be offered for patients with previous implantation failure, older maternal age or thick zona pellucida.

The LAH procedure

Using a precision laser, a small opening is made in the zona pellucida to assist embryo hatching and potential implantation. Using a high-precision laser under microscopic control, embryologists create a tiny opening or thin the zona immediately before transfer. The process is very quick and safe when performed by experienced staff.

Benefits

May improve implantation rates for selected cases; discussed on an individual basis with your fertility specialist. LAH may improve implantation rates in the selected patient groups and is performed with modern laser systems to minimise risk.

Frequently Asked Questions

Laser Assisted Hatching is an advanced laboratory technique used in IVF (in vitro fertilization) where a small hole is made in the outer shell (zona pellucida) of an embryo using a precise laser. This helps the embryo hatch and implant more easily into the uterus.

LAH is generally recommended for women of advanced maternal age (typically over 37-38 years), patients with previous failed IVF cycles, embryos with a thickened zona pellucida, frozen-thawed embryo transfers (FETs), embryos of poor quality, and patients with high follicle-stimulating hormone (FSH) levels.

Yes, numerous studies and clinical observations suggest that LAH can lead to higher clinical pregnancy rates, especially in indicated patient populations. LAH allows the embryo to more readily interact and attach to the uterine lining, thereby increasing the chances of successful implantation.

Yes, LAH is considered safe for the embryo. Compared to older methods of assisted hatching (such as chemical or mechanical methods), laser technology offers unparalleled precision and control, minimizing the risk of damage to the embryo. Extensive research has confirmed that LAH does not increase the risk of congenital abnormalities or affect the healthy development of the baby.

While LAH can significantly improve the chances of successful implantation and pregnancy, it does not guarantee pregnancy. Individual results vary depending on various factors including age, overall reproductive health, egg quality, sperm quality, and the specific cause of infertility. LAH should be considered as one of several options to optimize IVF success rates.
