Decoding PGT-A & PGT-M/SR: A Comprehensive Guide to Genetic Screening in Fertility Treatments

These powerful tools in the realm of IVF offer couples the chance to understand their future child’s genetic health before pregnancy begins. Dr. Anthony Marren, an expert in reproductive medicine, believes that empowering his patients with knowledge about these procedures is as crucial as the procedures themselves.

Understanding PGT-A and PGT-M/SR:

Both PGT-A and PGT-M/SR are adjuncts to the IVF process, providing a genetic preview of embryos prior to transfer. Here’s a closer look at each:

 

PGT-A: A Precision Tool for Chromosomal Screening PGT-A, formerly known as PGS, assesses embryos for the correct number of chromosomes. Anomalies in chromosomal count – like the addition or subtraction of a chromosome – are common causes behind miscarriage and implantation failures. PGT-A aims to enhance the likelihood of a successful pregnancy by selecting chromosomally normal embryos.

 

PGT-M/SR: Targeted Testing for Genetic Disorders and Structural Rearrangements PGT-M (formerly PGD) is used to detect specific inherited conditions. It’s invaluable for couples who may carry genes for disorders like Huntington’s disease or Tay-Sachs, offering a preventive glimpse that can guide crucial decisions. PGT-SR, another form of the test, focuses on identifying structural rearrangements in the chromosomes.

 

The Journey Through PGT-A/PGT-M/SR:

The path to PGT-A or PGT-M/SR begins with the well-known steps of IVF. Once the embryos reach a suitable stage, typically five to six days after fertilisation, a biopsy is performed. This procedure is delicate but, in skilled hands like Dr. Marren’s, it’s precise and safe. The removed cells undergo genetic sequencing, revealing invaluable information about each embryo’s genetic health.

 

Dr. Marren’s Approach to Genetic Screening:

Dr. Marren approaches PGT-A and PGT-M/SR with a comprehensive lens. His priority is not just the success of the procedure but also the comfort and understanding of his patients. Each couple is guided through the technicalities, the potential outcomes, and the emotional considerations involved. Dr. Marren’s philosophy is centred on informed choices, offering clarity and support in decisions that are deeply personal.

Statistical Insights

 

  • PGT-A can significantly improve the implantation rates by selecting chromosomally normal embryos, with studies suggesting a success rate increase of up to 60% for women over 35.
  • The use of PGT-A has nearly doubled the number of IVF cycles resulting in live births for women aged 40 and above.
  • GT-M provides reassurance to parents with known genetic disorders, reducing the risk of passing these conditions to their children.P

Dr. Marren’s Unique Approach:

What sets Dr. Marren apart is his dual focus on cutting-edge technology and the human touch. With a thorough academic background and a compassionate demeanour, he ensures that his patients are not just undergoing a procedure but are engaging in a life-changing experience that’s rooted in care and understanding.

 

Potential and Considerations:

PGT-A and PGT-M/SR are transformative in the landscape of fertility, offering paths to parenthood that were once less certain. Dr. Marren’s expertise in these procedures is matched by his dedication to patient support, ensuring that each couple’s journey is not just medically sound but also emotionally supported.

 

Call to Action:
If PGT-A or PGT-M/SR seems like a step you are considering, or if you’re simply seeking more information, Dr. Marren is available to explore the possibilities with you. His practice is not just about treatments; it’s about creating families and ensuring each step is taken with confidence and support.
