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.

What are the benefits of Non-Invasive Genetic Screening (NIGS)?
NIGS is a non-invasive, safe, and effective method for screening embryos, reducing the risk of miscarriage and birth defects.
Does embryo screening affect the chances of a successful pregnancy?
Embryo screening increases the likelihood of a successful pregnancy by selecting genetically healthy embryos.
Can embryo screening reveal the gender of the embryos?
Yes, embryo screening can determine the gender of embryos, which may be important for couples with specific genetic concerns.
Can all embryos be screened, or are there specific criteria?
Typically, all embryos created through IVF can undergo screening. However, it is usually recommended for patients with specific concerns, such as advanced maternal age or previous genetic issues.
How long does it take to receive the screening results?
Screening results are typically available within a few days, allowing for the timely selection of embryos for transfer.
Is Invasive PGT more accurate than NIGS?
Yes, Invasive PGT is more accurate as it directly analyzes the embryo's DNA. However, it involves a small biopsy, which some patients may prefer to avoid.
Are there any risks or side effects associated with embryo screening?
Both NIGS and Invasive PGT are safe procedures with minimal risks. Invasive PGT may carry a slight risk of damage during the biopsy.
How much does embryo screening cost, and is it covered by insurance?
The cost of embryo screening varies, and insurance coverage depends on the specific policy. Patients should consult with their healthcare providers for detailed pricing.
Are there any ethical concerns related to embryo screening?
Some individuals or religious groups may have ethical concerns about embryo screening. It is essential to discuss any ethical considerations with your healthcare provider.
Can embryo screening be performed with frozen embryos?
Yes, both NIGS and Invasive PGT can be applied to frozen embryos, ensuring that previously frozen embryos are free from genetic abnormalities.
