Embryo screening, also known as pre-implantation genetic testing (PGT), is a groundbreaking procedure offered by Aster CMI Hospital's IVF department. It plays a pivotal role in the world of assisted reproductive technology, providing couples with the opportunity to screen embryos for genetic abnormalities before implantation. This article explores the significance of embryo screening, the process it involves, and answers ten frequently asked questions regarding this advanced fertility treatment.
Understanding Embryo Screening
Embryo screening, which encompasses both Non-Invasive Genetic Screening (NIGS) and Invasive PGT, is designed to identify genetic anomalies within embryos created through in vitro fertilization. The primary objectives of embryo screening include:
Genetic Health: Ensuring that the embryos selected for transfer are free from genetic disorders, increasing the likelihood of a successful pregnancy and a healthy child.
Improved Pregnancy Rates: Enhancing the chances of a successful pregnancy by selecting embryos with the highest genetic potential.
Reducing the Risk: Reducing the risk of implanting embryos with genetic abnormalities, which can result in miscarriages or birth defects.
The Embryo Screening Process
The process of embryo screening at Aster CMI Hospital involves a series of carefully coordinated steps:
Ovulation Stimulation: The patient undergoes controlled ovarian hyperstimulation with hormone medications to produce multiple eggs.
Egg Retrieval: Mature eggs are retrieved through a minor surgical procedure under ultrasound guidance.
Fertilization: Sperm is used to fertilize the retrieved eggs, creating embryos in the laboratory.
Screening Options:
- Non-Invasive Genetic Screening (NIGS): This technique involves the evaluation of embryo cell-free DNA using a simple blood sample from the mother. It provides a non-invasive method for identifying genetic abnormalities such as aneuploidy (abnormal chromosome numbers).
- Invasive PGT: In this method, a small biopsy is taken from the embryos, and their DNA is analyzed for genetic abnormalities. This is the most accurate form of genetic screening.Embryo Selection: Based on the screening results, only embryos free from significant genetic anomalies are chosen for transfer.
Cryopreservation: If there are excess healthy embryos, they can be cryopreserved for future use.
Embryo Transfer: The selected embryos are transferred into the woman's uterus during a carefully timed procedure.
Conclusion
Embryo screening, whether through Non-Invasive Genetic Screening (NIGS) or Invasive PGT, has revolutionized the world of fertility treatment, providing couples with the ability to select genetically healthy embryos and increase their chances of a successful pregnancy. Aster CMI Hospital's IVF department specializes in this cutting-edge procedure, ensuring the highest level of care and expertise for individuals and couples on their journey to parenthood.
