IVF treatment is a significant investment, both financially and emotionally. Starting the journey with great hope only to face failure two or three times can lead couples to ask, “Will we ever be able to become parents?” In medical literature, this condition is known as “Recurrent Implantation Failure” (RIF), and it is actually a sign that a new roadmap needs to be drawn.
Why Does Implantation Fail?
When analyzing the reasons behind failure, we investigate three fundamental areas:
The Embryo Factor: Even if an embryo appears to be of high quality under a microscope, it may be genetically flawed. Especially in cases of advanced maternal age or severe male infertility, genetic abnormalities can prevent implantation.
The Uterine (Endometrium) Factor: The structure, blood supply, and thickness of the uterine lining may not be suitable for accepting the embryo. Fibroids, polyps, or adhesions resulting from past infections can act as “silent” obstacles.
Immunological and Clotting Issues: The mother’s immune system may perceive the embryo not as a guest, but as “foreign tissue” and attack it. Additionally, a tendency for blood clotting can cause blockages in the vessels that nourish the embryo, halting its development.
First Attempt and Recurrent Attempts: What Do the Numbers Say?
Statistically, the success rate for the first attempt in a young patient group is around 40% to 50%. While this figure seems high, it means that one out of every two couples may receive a negative result the first time.
The First Attempt (The Learning Process): The first treatment is often a phase where the doctor gets to know the patient’s body. The ovaries’ response to medication and the resulting embryo quality become clear during this initial stage.
Second and Third Attempts: When the protocol is revised using data obtained from the first attempt, the chance of success usually remains stable or increases.
Cumulative Success Rate: What truly matters in IVF is “cumulative” success. Scientific studies show that for couples who persevere, the total success rate can reach 80-90% after three attempts.
How Many Attempts Are Considered “Normal”?
Medically, completing three full cycles (egg retrieval and transfer processes) is generally considered a standard waiting period. If pregnancy has not been achieved despite high-quality embryos over three attempts, it is “normal” to proceed to the advanced investigations mentioned above (genetic screening, uterine resting, etc.).
When Should You Stop?
There is no single answer to “When should we stop?” This depends on the woman’s ovarian reserve, the couple’s psychological resilience, and the doctor’s medical judgment. However, thanks to advancing technology, knowing that many families have held their healthy babies after their 4th or 5th attempt is valuable for maintaining motivation.
Remember: failing the first time in IVF is not a “defeat,” but a “data collection” phase on the road to the right strategy.
Next-Generation Diagnostic and Treatment Methods
Many failures that were once labeled “unexplained” now have solutions:
Office Hysteroscopy: By observing the inside of the uterus with a camera, we can see even the smallest details that might be missed on an ultrasound and intervene in the same session. A small “scratch” made to the uterus can increase blood flow and implantation factors in that area.
EMMA and ALICE Tests: These tests allow us to detect the balance of beneficial bacteria in the uterus and identify any chronic inflammation, allowing for targeted treatment.
Immune Serums (Intralipid): To prevent rejection caused by the immune system, we apply special serum treatments before and after the transfer to make the uterus more “hospitable.”
There is a reason not to give up. Recurrent failures are not the beginning of the end, but the beginning of a detailed investigation. Every unsuccessful attempt is an experience that teaches us what not to do in the next one. With correct analysis and patient follow-up, success is possible even in the most challenging cases.
