How to Solve Recurrent Miscarriage with PGT Technology (Step-by-Step Guide)
I am Dr. Olivia Bennett, a medical consultant specializing in assisted reproduction and family building. Recurrent pregnancy loss (RPL) affects approximately 1-2% of couples, often leaving them with the frustrating diagnosis of "unexplained miscarriage." Throughout my career, I have helped hundreds of families move past this heartbreak using advanced genetic testing. By integrating third-generation IVF technology, we can identify and eliminate chromosomal abnormalities—the root cause of over 70% of early losses—before implantation. This guide provides a scientific roadmap for couples seeking to build a healthy family through precision medicine and genomic screening.
The most effective solution for recurrent miscarriage is PGT-A technology, which ensures only chromosomally normal (euploid) embryos are selected for transfer, maximizing the chance of a full-term pregnancy.

What is PGT (Preimplantation Genetic Testing)?
PGT is the cornerstone of third-generation IVF. It involves analyzing the genetic makeup of embryos created through IVF before they are transferred to the uterus. For those struggling with causes of recurrent miscarriage, PGT acts as a critical filter, identifying chromosomal numerical or structural issues that are responsible for the majority of early pregnancy failures.
Unlike traditional IVF, which relies on visual morphology (how an embryo looks), PGT looks at the DNA. This is crucial because even a "perfect-looking" embryo can have an extra or missing chromosome (aneuploidy), which almost always leads to miscarriage or a child with a genetic syndrome.
Core Classifications of PGT
PGT-A (Screening)
Screens all 23 pairs of chromosomes for aneuploidy (e.g., Down syndrome, Trisomy 16). Essential for advanced maternal age and recurrent miscarriage cases to ensure "euploid" status.
PGT-M & PGT-SR
PGT-M targets single-gene disorders (e.g., cystic fibrosis), while PGT-SR detects structural rearrangements like translocations, which are common in couples with RPL.
Who Should Consider PGT?
- Women with 2 or more consecutive miscarriages (Recurrent Pregnancy Loss).
- Women over the age of 35 (Advanced Maternal Age) where egg quality declines.
- Couples with a known history of balanced translocations or inversions.
- Patients who have experienced multiple failed IVF transfers (Implantation Failure).
- Male factor infertility involving high sperm DNA fragmentation.
- Those seeking third-generation IVF technology for family balancing or disease prevention.
The PGT Journey: A 4-Step Guide
Step 1: Comprehensive Evaluation & Protocol Design
A 1-on-1 video consultation with RSMC specialists to analyze miscarriage history, hormone levels (AMH/FSH), and uterine health. We design a custom stimulation protocol to maximize egg yield.
✅ Goal: A clear medical roadmap and optimized ovarian response.
Step 2: Ovarian Stimulation & ICSI Fertilization
Controlled stimulation followed by a safe egg retrieval. We use ICSI (Intracytoplasmic Sperm Injection) to ensure fertilization and prevent "paternal DNA contamination" during testing.
✅ Goal: Obtaining high-quality mature eggs and successful fertilization.
Step 3: Blastocyst Culture & Laser Biopsy
Embryos are cultured to the blastocyst stage (Day 5-7). Expert embryologists use a precision laser to biopsy 5-10 cells from the trophoblast (future placenta) while the embryo is safely frozen.
✅ Goal: Successful biopsy without compromising the inner cell mass (future baby).
Step 4: NGS Analysis & Precision Transfer
Using Next-Generation Sequencing (NGS), we identify the healthiest embryos. Understanding the differences between PGT-A and PGT-M ensures the right test is applied before a Frozen Embryo Transfer (FET).
✅ Goal: Transferring a healthy, euploid embryo into an optimized uterine environment.

Frequently Asked Questions
1. How does PGT prevent miscarriage?
By screening for chromosomal abnormalities—the cause of 70% of early miscarriages—PGT ensures only healthy embryos are transferred, drastically reducing the risk of loss and increasing live birth rates.
2. Is the biopsy safe for the embryo?
Yes. At RSMC, we biopsy only the trophoblast (future placenta) at the blastocyst stage. Research shows this has a negligible impact on fetal development compared to older Day-3 biopsy methods.
3. How long does it take to get PGT results?
Typically, Results are available within 2‑3 weeks following biopsy. During this time, embryos remain safely cryopreserved in our laboratory.
4. Can PGT determine the gender of the embryo?
Yes. PGT-A analyzes all chromosomes, including the sex chromosomes (X and Y), allowing for family balancing if desired by the parents.
5. What is the cost of PGT in the US?
Standard PGT-A screening typically ranges from $5,000 to $7,000 depending on the number of embryos. RSMC offers transparent, all-inclusive packages to help families plan their budgets effectively.
Recurrent miscarriage is a profound challenge, but with modern science, it is not an endpoint. RSMC is here to provide the technology, expertise, and emotional support you need to achieve a healthy birth.
