Embryo Biopsy for PGS/PGD is a highly specialised laboratory technique performed during an IVF cycle to evaluate embryos for genetic or chromosomal irregularities before they are transferred into the uterus.
During the biopsy, a skilled embryologist removes a few cells (usually 5–8) from the trophectoderm, the outer layer of the blastocyst that later forms the placenta. The inner cell mass — the portion that develops into the baby — remains untouched.
Why It Matters
Every human embryo should contain 46 chromosomes (23 from the mother and 23 from the father). If there is an extra or missing chromosome (aneuploidy), implantation failure or miscarriage may occur. Similarly, when either parent carries defective genes, there is a risk of transmitting serious inherited disorders.
Embryo biopsy and genetic testing enable the selection of embryos that are both chromosomally balanced and genetically healthy. This significantly enhances the likelihood of a successful pregnancy and a healthy child.
Scientific Perspective
Over the past two decades, embryo-testing technology has evolved from basic FISH (Fluorescence in Situ Hybridisation) to aCGH (Array Comparative Genomic Hybridisation) and now to NGS (Next Generation Sequencing). At KIC Delfinium, we use NGS, the gold-standard method, offering accuracy above 98% in detecting chromosomal and genetic irregularities.
Not every IVF patient needs embryo biopsy. Our fertility experts recommend it when specific risk factors are present.
Women aged 35 and above have a higher likelihood of producing eggs with abnormal chromosome numbers. PGS helps detect embryos with normal chromosomal composition, improving implantation rates and reducing miscarriage chances.
Repeated pregnancy loss often points to chromosomal anomalies. PGS identifies embryos with correct chromosome sets, giving couples a stronger chance at carrying to term.
Couples who are carriers of genetic diseases such as thalassemia, cystic fibrosis, Huntington’s disease, sickle cell anaemia, or muscular dystrophy benefit from PGD. It ensures only unaffected embryos are transferred.
After several unsuccessful IVF cycles, chromosomal or genetic issues may be suspected. PGS reveals these hidden causes and guides the transfer of the most viable embryos.
In some couples, infertility persists even when all other parameters seem normal. Embryo biopsy can reveal subtle chromosomal imbalances affecting embryo development.
Abnormal sperm morphology or DNA fragmentation can lead to genetic errors in embryos. PGS ensures selection of embryos with the highest genetic integrity.
If one partner carries a balanced chromosomal translocation, PGD helps identify embryos without these structural rearrangements, preventing implantation failures or miscarriages.

The female partner receives tailored hormonal stimulation to produce multiple mature eggs. Follicular growth is closely monitored through ultrasound and blood tests. Once ready, the eggs are collected through a short, minimally invasive outpatient procedure.
The retrieved eggs are fertilised with sperm using either standard IVF or ICSI (Intracytoplasmic Sperm Injection). Embryos are cultured in a nutrient-rich medium under precise temperature and pH conditions for five to six days until they reach the blastocyst stage.
At the blastocyst stage, a laser is used to create a microscopic opening in the outer shell (zona pellucida). A few trophectoderm cells are gently aspirated. This technique avoids touching the inner cell mass and preserves embryo viability.
The biopsied cells are transported to a partner genetic laboratory.
• For PGS: NGS or aCGH is used to analyse all 23 chromosome pairs for aneuploidy or translocations.
• For PGD: DNA from the biopsied cells is examined for specific gene mutations using PCR (Polymerase Chain Reaction) or NGS panels.
After biopsy, embryos are rapidly frozen using vitrification, a technique that prevents ice-crystal formation and maintains structural integrity. They remain stored in liquid nitrogen while results are awaited.
Once results are ready (typically 7–10 days), our specialists identify chromosomally normal or disease-free embryos. A comprehensive report is shared with the couple, explaining which embryos are suitable for transfer.
In a later cycle, the selected embryo is thawed and transferred into the uterus using a thin catheter. This is a painless, outpatient procedure requiring no anaesthesia.
After 12–14 days, a blood β-hCG test confirms pregnancy. Our care team continues hormonal and ultrasound monitoring to ensure stable implantation and foetal development.
Although often used interchangeably, PGS and PGD serve distinct purposes:
| Aspect | PGS (Pre-implantation Genetic Screening) | PGD (Pre-implantation Genetic Diagnosis) |
| Primary Goal | Detects chromosomal number abnormalities (aneuploidy) | Detects specific inherited gene mutations |
| Use Cases | Advanced maternal age, recurrent miscarriage, multiple IVF failures | Family history of single-gene disorders |
| Techniques Used | NGS / aCGH / FISH | PCR / NGS targeted panel |
| Conditions Detected | Down’s (Trisomy 21), Edwards (Trisomy 18), Turner’s (X0) etc. | Thalassemia, Cystic Fibrosis, Sickle Cell, Huntington’s |
| Outcome | Identifies chromosomally normal embryos for transfer | Selects embryos free of known genetic mutations |
| Time to Results | 7–10 days | 10–14 days (depending on test type) |
Both techniques ultimately improve IVF outcomes by ensuring that only genetically competent embryos are used for implantation.
By transferring only chromosomally normal embryos, success rates per cycle increase dramatically. Couples experience higher implantation rates and fewer cycle cancellations.
PGD allows couples with inherited genetic risks to have children free from the disease, eliminating the need for post-conception screening or medical termination.
Many miscarriages result from chromosomal abnormalities. PGS reduces this risk by ensuring only viable embryos are implanted.
Healthy embryos identified early reduce the number of treatment rounds needed, saving time, cost, and emotional strain.
Embryos confirmed as genetically normal are more likely to develop into healthy full-term babies with reduced pregnancy complications.
With detailed genetic data, couples can make confident, informed choices regarding embryo transfer and family planning.

An embryo biopsy is a laboratory procedure performed during an IVF cycle where a few cells are carefully removed from a developing embryo. This sampling allows genetic testing without harming the embryo. The process is carried out using advanced microscopes and laser precision to ensure embryo safety. The collected cells are analyzed for chromosomal or genetic abnormalities, helping embryologists identify healthy embryos for transfer. It’s a key step in ensuring higher IVF success rates and reducing the risk of inherited disorders.
An embryo biopsy is performed to identify chromosomal or genetic abnormalities in embryos before implantation. The main purpose is to select healthy embryos that have the highest potential to develop into a successful pregnancy. This process also helps reduce the risk of passing hereditary diseases to the child. By detecting abnormalities early, the clinic ensures that only genetically normal embryos are transferred to the uterus, improving success rates and promoting healthy pregnancy outcomes for couples undergoing IVF.
PGS (Preimplantation Genetic Screening), now known as PGT-A, is a test that checks embryos for chromosomal abnormalities before they are implanted. It helps detect conditions like missing or extra chromosomes that may cause miscarriage or genetic disorders. The screening is performed on biopsied cells from the embryo without harming it. PGS enables embryologists to transfer only chromosomally normal embryos, improving the chances of a healthy pregnancy and reducing the risk of implantation failure or early miscarriage.
PGD (Preimplantation Genetic Diagnosis), now referred to as PGT-M, is used to detect specific genetic diseases or mutations in embryos before implantation. It’s particularly beneficial for couples who have a known family history of inherited disorders like thalassemia, cystic fibrosis, or sickle cell anemia. During PGD, cells from the embryo are tested to ensure they are free from specific mutations. This allows couples to prevent passing genetic diseases to their child, ensuring a healthier pregnancy and baby.
An embryo biopsy is typically performed at the blastocyst stage, which is around the fifth or sixth day of embryo development. At this stage, the embryo has grown enough to allow safe removal of a few cells from the outer layer (trophectoderm) without disturbing the part that forms the baby. Performing the biopsy at this time ensures accurate results and minimal impact on embryo viability, allowing doctors to select the best embryos for transfer after testing.
Yes, when performed by skilled embryologists using advanced micromanipulation tools, embryo biopsy is a safe procedure. The technique involves removing only a few cells from the embryo’s outer layer, which later forms the placenta, not the fetus itself. Modern technology ensures that the biopsy does not interfere with normal embryo development. The embryos are closely monitored after biopsy to confirm their continued healthy growth before being transferred or frozen for future use.
With advanced technology and experienced professionals, embryo biopsy rarely causes any harm. The process is done under controlled conditions using laser-assisted methods to minimize stress on the embryo. Only a few cells are removed, which does not affect its ability to implant or grow into a baby. Studies have shown that embryos that undergo biopsy and genetic testing develop normally, and the risk of damage is minimal when handled by an expert embryology team.
Embryo biopsy is recommended for couples who are at risk of passing on genetic disorders, have experienced recurrent miscarriages, or have had multiple failed IVF cycles. It is also beneficial for women over 35, as the risk of chromosomal abnormalities increases with age. Additionally, couples with a family history of inherited diseases or carriers of genetic mutations can opt for embryo biopsy to ensure the health of their future child through early genetic screening.
Yes, embryo biopsy combined with PGS/PGD testing can significantly improve IVF success rates. By selecting embryos that are genetically normal and free from abnormalities, the chances of successful implantation and a healthy pregnancy increase. It also reduces the likelihood of miscarriage and prevents the transfer of affected embryos. This approach helps couples achieve pregnancy more efficiently and safely, making IVF outcomes more predictable and emotionally reassuring for intended parents.
PGD can detect a wide range of inherited diseases caused by specific gene mutations. These include thalassemia, cystic fibrosis, sickle cell anemia, Huntington’s disease, muscular dystrophy, and hemophilia, among others. By identifying these conditions at the embryonic stage, couples can prevent passing on serious genetic disorders to their children. The test ensures that only unaffected embryos are selected for transfer, greatly reducing the emotional and medical risks associated with genetic illnesses in offspring.
PGS, also known as PGT-A, checks for chromosomal abnormalities like missing or extra chromosomes (aneuploidy). Such abnormalities are a leading cause of implantation failure, miscarriage, or birth defects. The test provides vital insights into embryo health and helps embryologists select embryos with the correct number of chromosomes for transfer. By identifying chromosomally normal embryos, PGS increases IVF success rates and reduces the emotional strain of repeated failed cycles or pregnancy loss.
Yes, embryos that have been previously frozen can be biopsied after proper thawing. The procedure is performed using the same precision techniques as fresh embryos. Once the biopsy is completed, the embryo can either be refrozen (vitrified) until the results are available or transferred immediately depending on the treatment plan. This flexibility allows couples to test stored embryos and ensures that only genetically healthy ones are selected for transfer in future cycles.
No, anesthesia is not required for an embryo biopsy because the procedure is performed in a laboratory, not inside the patient’s body. The biopsy involves handling the embryo under a microscope using micromanipulation tools, which causes no pain or discomfort to the patient. The process is entirely external and managed by embryologists. The couple’s role is limited to providing eggs and sperm during IVF; the biopsy itself is a scientific, pain-free laboratory procedure.
Yes, embryos that have undergone biopsy can be safely frozen using a technique called vitrification. This ultra-rapid freezing process prevents ice crystal formation and preserves the embryo’s cellular structure. After testing, only genetically healthy embryos are selected for freezing, ensuring optimal quality for future transfers. When thawed, these embryos maintain high survival rates and implantation potential. Freezing biopsied embryos also allows couples to plan future pregnancies with convenience and confidence.
The results of embryo biopsy guide fertility specialists in selecting the healthiest embryos for transfer. If an embryo is found to be chromosomally normal or free of genetic disease, it is prioritized for implantation. Abnormal embryos are not transferred, preventing potential miscarriages or genetic disorders. The findings also help doctors plan future IVF cycles and advise couples about genetic risks, increasing the likelihood of a healthy and successful pregnancy outcome.
Yes, embryo biopsy with PGS/PGD testing helps prevent miscarriages by identifying embryos with chromosomal or genetic abnormalities before transfer. Many miscarriages occur due to such abnormalities, which lead to failed implantation or early pregnancy loss. By transferring only normal embryos, the risk of miscarriage drops significantly. This process provides couples greater confidence and emotional relief, ensuring a safer pregnancy journey and better chances of bringing home a healthy baby.
After the biopsy, embryos are carefully cultured and monitored for development. They are either frozen until genetic test results arrive or transferred immediately if results are available. The removed cells are sent to a specialized genetic laboratory for analysis. Throughout this process, strict lab protocols ensure embryo safety and viability. The embryos are stored in temperature-controlled incubators, and their development is tracked using time-lapse imaging to ensure their continued health and growth.
While embryo biopsy offers valuable insights, it’s not necessary for every IVF patient. It is mainly recommended for couples with genetic risks, older maternal age, recurrent miscarriages, or failed IVF attempts. For younger couples with no family history of genetic disorders, standard IVF without biopsy is usually sufficient. The decision should always be made after thorough consultation with fertility specialists, who assess individual medical conditions and advise whether the procedure is beneficial.
PGS and PGD tests are highly accurate, typically offering results with 95–99% reliability. Advanced genetic testing techniques analyze embryo DNA to detect abnormalities or specific mutations. However, while extremely precise, no test is 100% foolproof. Factors such as sample quality or mosaicism (mixed cell types) may slightly affect results. Despite this, these tests remain among the most effective tools for improving IVF outcomes and ensuring healthier pregnancies for aspiring parents.
Embryo biopsy combined with PGS/PGD testing offers multiple benefits — it improves IVF success rates, reduces the risk of miscarriage, and helps prevent genetic diseases. By identifying healthy embryos, couples experience fewer failed cycles and more predictable outcomes. It also allows single-embryo transfers, reducing the risk of multiple pregnancies. This advanced screening ensures better family planning and peace of mind, making the IVF journey safer, more efficient, and emotionally reassuring for couples.
