Assisted hatching is a technology which helps embryos to hatch from its outer protective shell and attach to the womb of the woman. Pregnancy cannot occur unless the human embryo hatches. The unfertilized egg is surrounded by a shell called zonapellucida which ensures that only one sperm cell enters and thus fertilizes the egg. After fertilization of the egg, zonapellucida keeps the cells of the embryo together. Laser assisted hatching is one out of several methods to help the fertilized egg to hatch and attach to the uterus. It requires less handling of the embryo and is faster than the other assisted hatching methods.
If you are undergoing IVF, that does not mean you will be recommended LAH. Experts believe that LAH might bring successful pregnancy in certain types of couples. After analyzing all your medical records and infertility history, your fertility doctor can determine if LAH can help you.
Generally, in the following conditions, assisted hatching may improve the pregnancy rate.The zona pellucida, or outer shell, of older women’s eggs tends to be thicker. Women with high follicle-stimulating hormone (FSH) levels experience the same issue. In certain situations, the egg will not hatch and will not connect to the womb. All of these cases of infertility can benefit from assisted hatching.
Additionally, research indicates that frozen or thawed embryos have a hard zona pellucida, making it challenging for them to hatch and implant. A hole in the outer shell will be made via laser-assisted hatching, which will make it simple to implant the embryo.
LAH procedure is carried out on the 3rd day after the IVF cycle when the embryo is still in the lab. In this technique, a specialized laser is used to create a breach in zona pellucida. Laser technology allows a more controlled approach and is the safest and most effective technique. Though making a small crack in the zona pellucida sounds like a simple technique, it involves precise procedures and a skilled technician to perform it. The embryology lab needs to have specialized instruments to perform this advanced technology. The whole process is fairly quick and takes only a few seconds.
In this process, laser shots are used that softens the zona pellucida, which helps to create an opening. The laser will not come in direct contact with the embryo and is performed with utmost delicacy and precision. This procedure ensures the safety of the embryo.
It is crucial to understand that embryos usually implant in the womb during IVF procedures and that hatching is a natural process. A contemporary strategy could be required because failure to hatch is a rare cause of infertility. Additionally, it’s crucial to talk over the benefits and drawbacks of receiving LAH treatment with your reproductive specialist. You should also think about the extra cost associated with this operation.
