Greetings from Amma Bear,
If you've ventured into the world of IVF, you might have come across the term PGT or Preimplantation Genetic Testing. This advanced genetic screening is often hailed as a beacon for hopeful parents, but as with all things medical, it's layered. Today, I aim to shed light on the intricacies of PGT, helping you understand its merits, limitations, and the spectrum of medical opinions surrounding it.
Benefits of PGT
Reduced Risk of Genetic Disorders: One of the primary reasons couples opt for PGT is to reduce the likelihood of passing on genetic disorders. By screening embryos for specific genetic mutations, PGT allows only healthy embryos to be transferred.
Increased Chances of IVF Success: With the ability to select embryos free from chromosomal abnormalities, the likelihood of successful implantation and a healthy pregnancy can increase.
Lower Miscarriage Rates: Chromosomal abnormalities are a significant cause of miscarriage. By transferring embryos that have been screened and deemed chromosomally normal, there's a reduced risk of miscarriage related to these abnormalities.
Drawbacks of PGT
Not 100% Accurate: No medical test is entirely foolproof. There is always a small chance of false positives or negatives[4].
Physical and Emotional Strain: The IVF process combined with PGT can be demanding, both physically due to the additional procedures, and emotionally, awaiting results.
Additional Costs: PGT adds to the overall expense of IVF, which might be a consideration for some couples.
Diverse Medical Perspectives
Pro PGT: Many fertility specialists advocate for PGT, especially for older women, couples with a history of genetic disorders, or those who've faced recurrent miscarriages. These professionals believe the benefits outweigh the drawbacks, particularly in increasing the chances of a healthy pregnancy.
Cautionary Approach: Some professionals believe that PGT should be used selectively, concerned about the implications of discarding embryos based on genetic information and the ethical considerations surrounding it.
Neutral Perspective: A few experts propose a case-by-case approach, determining the necessity of PGT based on individual medical histories and potential risks.
Closing your eyes and picking a path is not the way forward. Educate yourself, ask questions, seek multiple opinions, and make decisions rooted in understanding. Remember, your journey is uniquely yours, and while advice can guide, let your intuition and knowledge lead.
With admiration for the steps you’re making,
Amma Bear
