When couples begin an IVF journey, they often hear many new medical terms. IVF, ICSI, embryo freezing, blastocyst culture and genetic testing can all sound complicated, especially when you are already dealing with the emotional side of infertility. One term that frequently raises questions is PGD. Many intended parents ask, “What exactly is PGD?”, “Do we really need it?”, and, of course, “How much does PGD Cost in Nigeria?” The answer depends on the type of genetic testing required, the number of embryos being tested, the laboratory used, and whether additional genetic work is needed for a particular inherited condition. It is also worth noting that medical terminology has changed. What was traditionally called PGD (Preimplantation Genetic Diagnosis) is now commonly discussed under the broader term PGT (Preimplantation Genetic Testing). PGT-M is generally used when testing embryos for a specific inherited single-gene disorder, while PGT-A looks for chromosome-number abnormalities. For couples considering IVF in Nigeria, understanding these differences is important because the cost and purpose of testing can be very different. Current Nigerian cost information suggests that PGT can add a substantial amount to an IVF budget. One 2026 Nigeria fertility-cost guide estimates PGT-A/PGT-M at approximately ₦7 million to ₦10.5 million, excluding the underlying IVF treatment. These are planning figures rather than universal clinic prices. So, before you make a financial decision, it is important to understand exactly what the testing includes. What Is PGD? PGD stands for Preimplantation Genetic Diagnosis. In simple terms, it is a genetic testing approach used during an IVF cycle to examine embryos for certain genetic conditions before an embryo is transferred to the uterus. Today, the terminology is more commonly grouped under Preimplantation Genetic Testing (PGT). For example: The exact test recommended depends on the medical and genetic situation of the couple. This is why a fertility specialist or genetic counsellor should determine whether testing is appropriate rather than choosing it simply because it is available. Why Is PGD Used During IVF? Imagine that a couple is known to carry a particular inherited genetic condition. During IVF, several embryos may be created. Without genetic testing, doctors may not know whether an embryo carries the specific condition being investigated. With an appropriate PGT approach, cells from embryos can be tested in a specialized laboratory before a suitable embryo is considered for transfer. The goal is to provide additional genetic information that can help doctors and intended parents make informed decisions about embryo selection. However, PGD/PGT does not guarantee a pregnancy or a healthy baby. It is a testing tool, not a guarantee of outcome. PGD Cost in Nigeria The PGD Cost in Nigeria varies considerably depending on the type of test and the laboratory performing it. For 2026 planning purposes, one Nigerian fertility-cost guide estimates PGT-A/PGT-M at approximately ₦7,000,000–₦10,500,000, with IVF costs excluded. Other Nigerian sources give lower estimates for some forms of PGT, demonstrating how widely prices can vary between providers and testing arrangements. Therefore, it would be misleading to tell every patient that PGD has one fixed price in Nigeria. Does PGD Cost Include IVF? Usually, you should not assume that it does. This is one of the most important things to understand when calculating the total treatment budget. PGT/PGD is performed on embryos created through IVF. Therefore, the complete treatment may involve separate costs for: So if a clinic tells you that genetic testing costs a particular amount, ask whether that figure covers only the genetic laboratory component or also includes embryo biopsy and related laboratory procedures. What Factors Affect PGD Cost in Nigeria? 1. Type of Genetic Test The type of PGT required can significantly affect the price. Testing for a specific inherited disorder may require a different laboratory process from chromosome screening. For example, PGT-M is designed around a particular single-gene condition, while PGT-A examines chromosome number. 2. Number of Embryos Tested Another major factor is the number of embryos requiring testing. If more embryos are biopsied and tested, the laboratory cost may increase depending on the provider’s pricing model. This is why couples should ask whether their quotation is: 3. Genetic Condition Being Investigated If the family has a known inherited disorder, the genetic laboratory may need specific information about the condition before testing can begin. The complexity of the test can therefore influence the overall price and preparation time. 4. Laboratory Used PGT requires specialized genetic laboratory facilities. Some fertility centres may coordinate testing with an external genetics laboratory. This can affect: How Does PGD Work? The process usually begins with IVF because embryos need to be created before they can undergo embryo biopsy and genetic testing. Step 1: Fertility Consultation The fertility specialist reviews your reproductive history and determines whether genetic testing may be appropriate. Step 2: Genetic Assessment If there is a known inherited condition, genetic counselling may be recommended to understand the condition and determine which test is appropriate. Step 3: IVF Eggs are collected and fertilized in the laboratory. Step 4: Embryo Development The resulting embryos are monitored as they develop. Step 5: Embryo Biopsy A small number of cells are carefully removed from an embryo for genetic analysis. Step 6: Genetic Testing The sample is sent for the appropriate genetic test. Step 7: Embryo Freezing In many PGT programmes, embryos are frozen while genetic testing is completed. Step 8: Results The genetic laboratory provides a report indicating the findings relevant to the test performed. Step 9: Embryo Transfer Based on the medical plan and available results, an appropriate embryo may later be selected for frozen embryo transfer. Is PGD Necessary for Every IVF Patient? No. This is an important point. PGD or PGT is not automatically required for everyone undergoing IVF. A fertility specialist may recommend genetic testing when there is a specific medical reason. For example, PGT-M may be considered when one or both genetic parents are known to carry a particular inherited condition. PGT-A is a different test with a different purpose and should not simply be described as the
