Recurrent IVF Failure Management
What is Recurrent IVF Failure?
There could be several reasons for this. The quality of the embryo could be one of the most common factors. However, it is not as if an embryo is implanted in the womb every day. Several factors may have played a role. It could be structural. Fibroids, polyps, adhesions, or even an inflamed uterine lining could be the cause. It could also be hormone-related. This could be due to the presence of thyroid problems, insulin resistance, or even prolactin.
It is also important to remember that IVF failure is not a dead-end case. IVF failure means that we need more information.
Causes of Repeated IVF Failure
The case of recurrent IVF failure occurs when the couple is unable to attain a pregnancy after two or more cycles of IVF. In all the above cases, everything is done well. This is a very frustrating case. The couple could be confused. They could be thinking that everything is “good.” However, at this point, doing the same thing over and over could be of no great use. What could be of great use is taking one step back and looking at the embryo as well as the uterus, the hormones, and the various factors that could have been overlooked, including the male factors.
It may sometimes be associated with the DNA of the sperm. It may be for this reason that the receptiveness of the uterine lining and the timing of the embryo transfer may not be synchronized. This may be an important factor in the way the pregnancy will be. Small changes may make a big difference.
Evaluation & Diagnostic Approach
- Careful analysis of previous IVF cycle history, including response to stimulation and embryo development
- Hormonal studies, including thyroid function tests, prolactin levels, and metabolic parameters
- Transvaginal ultrasound with a detailed assessment of the uterine cavity
- Hysteroscopy in cases of abnormal uterine cavity
- Preimplantation genetic testing in selected cases
- Evaluation of receptivity of the endometrium
- High-tech semen analysis with DNA fragmentation testing
Advanced Treatment & Management Options
The treatment depends entirely on the findings. Some may need a change in the pattern of stimulation in order to increase the maturity of the eggs. Others may need ICSI if the fertilization process was not good enough. Some may need genetic tests of the embryos in order to find chromosomally normal embryos among certain age groups. If abnormalities are found in the uterus, correction of these abnormalities greatly improves the chances of implantation.
Sometimes, a change from a fresh to a frozen embryo transfer is what is necessary to improve the conditions of the endometrial tissue. In other instances, it is a boost to the thyroid hormones or a better metabolic state that is necessary. The approach is individualized; it is not repetitive.
