The advantages and disadvantages of PGD

The advantages and disadvantages of pre-implantation genetic diagnosis (PGD)

Most potential parents who would like to plan their pregnancy are concerned about the overall condition and well-being of their next child, its future, and the pregnancy itself, or if they need to undergo any genetic disorder diagnostic testing, which one they should go for and what would be the pros and cons of that testing.


As per the research and studies conducted on PGD testing, the majority of couples are tempted to undergo PGD to diagnose genetic disorders if available, thus, they are concerned about the pros and cons of PGD in particular. As a result, they are looking for better opportunities and ways to prevent passing on genetic disorders to their offspring.


There are different ways of genetic diagnosis and screenings to avoid chromosomal abnormalities and passing on genetic disorders to offspring, such as pre-implantation genetic diagnosis (PGD) and pre-implantation genetic testing for aneuploidy (PGT-A) which is also known as pre-implantation genetic screening (PGS).


Besides, there are other diagnostic tests that, analyze and detect chromosomal abnormality and genetic disorders but cannot prevent them. These testing are only able to advise the parents to decide whether the embryo or fetus should be maintained or aborted, such as amniocentesis, chorionic villus tests, and other non-invasive prenatal testing (NIPT), these aforementioned tests are different from each other in application, performance, methodologies, costs, and results.


The majority of potential parents choose pre-implantation genetic diagnosis (PGD) to avoid passing on genetic disorders to the next child, therefore, they are curious to know about the advantages and disadvantages of the PGD procedure.


It’s worth mentioning that, every treatment has its pros and cons, thus, TEBMED Tourism is providing potential parents with in-depth information about the advantages and disadvantages of pre-implantation diagnosis (PGD) procedures to familiarize them with the treatment process, treatment planning, and how to better facilitate their overall treatment here in Iran.

Why PGD?

First of all, potential parents who are concerned about passing on hereditary genetic disorders to their offspring are highly recommended to undergo pre-implantation genetic diagnosis (PGD) testing to avoid the possible existence of malicious chromosomal abnormalities in the embryos, such confidence which comes out of undergoing PGD will positively impact the parents’ psychological wellbeing and assists the female partner to have a stress free pregnancy.

The second importance that why couples would like to undergo PGD is that, some family members would like to find a bone marrow donor of their own family, who is supposed to provide matching stem cells for the patient.

The third importance is the timeline, it’s the fastest and simplest assisted reproductive treatment (ART) that requires only a day or two to undergo the PGD procedure.

Although undergoing pre-implantation genetic diagnosis (PGD) testing is an add-on cost to the fertility treatment, it is still inexpensive compared to other prenatal tests such as pre-implantation genetic screening (PGS), next generation sequencing (NGS), amniocentesis, chorionic villus sampling and non-invasive prenatal test (NIPT) and it (PGD) deserves to pay for. Hence, compared to other genetic diagnosis testing, PGD is highly recommended for patients with an austerity treatment budget.  

Advantages and Disadvantages of PGD

As per medical ethics, it’s the absolute right of every patient to know about the advantages and disadvantages of his/her treatment to wholeheartedly decide on whether to undergo PGD testing or hold back. Because every treatment process has its pros and cons along with its possible risks.
Therefore, we have come up with prominent and common advantages and disadvantages of pre-implantation genetic diagnosis (PGD) to educate our dear readers and patients to decide about their treatment with peace of mind.

Advantages of PGD:

• PGD is a very short, concise, and swift process and can be performed along with the IVF cycle.

• PGD is inexpensive diagnostic testing compared to other preimplantation and prenatal tests.

• It’s an easy and complication-free procedure that does not require anesthesia.

• Avoids the transfer of embryos that has limited chances of implantation or conceiving.

• Avoids the transfer of embryos that will lead to miscarriage or delivery of children with single or multiple syndromes.

• Increases chances of timely conceiving and pregnancy.
• After performing NIPT tests during the initial stages of pregnancy, those embryos that are detected as malfunctioning or identified as genetically disordered embryos will be aborted.

• Reduces the financial burdens of post-treatment of a child with a genetic disorder and pregnancy complications, which emerge due to the existence of a variety of genetic disorders and chromosomal abnormalities in the embryos.

• PGD reduces the risk of having a child with a specific single known genetic disorder and particularly prevents Down syndrome which is a very common chromosomal abnormality. (how to prevent Down syndrome)

• PGD reduces the chances of unwanted miscarriages in women, particularly in women who had previous experience with single or multiple unexplained miscarriages.

• Positive impact on the psychological well-being of the couples particularly on the female partner.

• PGD reduces the risk of miscarriage in women over the age of 36 and increases the chances of transferring the healthy embryo to achieve pregnancy.

Disadvantages of PGD:

• PGD is an invasive procedure that requires the embryologist to take a biopsy from the embryo for analyzing genetic disorders and chromosomal abnormalities. This technique will interfere with the natural status of the embryo and may decrease its quality to some extent.

• For some couples with low incomes, undergoing PGD along with IVF procedures will be expensive. In some countries, the medical and healthcare insurance companies are not covering the cost of PGD, so we are suggesting our patients clarify and finalize this before their departure to Iran.

• Sometimes the frozen embryos may not survive the thawing process.

• Although PGD has pros, its cons may also make the couples decide on whether they undergo PGD or not. It’s a difficult decision, but they have to decide.
