Laser-Assisted
1.Laser-Assisted Hatching:
Purpose: To help embryos implant into the uterine lining.
Process: After an embryo is cultured in the lab and before implantation, the outer layer of the embryo (the zona pellucida) can be very tough. Using a laser, embryologists create a small opening in this outer layer to facilitate easier implantation into the uterine wall.
Advantage: It can improve implantation rates and increase the chances of successful pregnancy, especially in cases where the zona pellucida is unusually thick or if the embryo has had difficulty hatching naturally.
2.Laser-Assisted Embryo Biopsy:
Purpose: To perform genetic testing on embryos (Preimplantation Genetic Testing or PGT).
Process: A laser is used to create a small hole in the zona pellucida to extract a few cells from the embryo. These cells are then analyzed for genetic abnormalities or specific traits.
Advantage: This technique allows for the selection of embryos that are free of genetic disorders, potentially improving the chances of a healthy pregnancy and reducing the risk of genetic diseases.
3.Laser-Assisted Egg Retrieval:
Purpose: To assist in the retrieval of eggs from the ovarian follicles.
Process: Lasers can sometimes be used to help break down the follicle walls and facilitate the extraction of eggs.
Advantage: This technique may improve the efficiency of egg retrieval in certain cases.
4.Laser-Assisted Sperm Injection:
Purpose: To enhance the ICSI (Intracytoplasmic Sperm Injection) procedure.
Process: A laser may be used to facilitate the injection of a single sperm into an egg by making it easier to penetrate the egg’s outer layer.
Advantage: This can improve the chances of successful fertilization, especially in cases where sperm quality is a concern.
Overall, laser technology in IVF helps enhance the precision and effectiveness of various procedures, potentially leading to higher success rates and better outcomes for patients undergoing fertility treatments.
