A doubt that creeps into every individual’s mind before adopting the In Vitro Fertilization (IVF) treatment is whether the treatment will be 100% effective. IVF treatment is not 100% effective all the time, although, in reality, it is one of the best Assisted Reproductive Techniques (ART) the modern medical technology has to offer.
IVF is a major ART treatment. It can enhance the fertility level of a woman even when the treatment technically fails. It is also found that the treatment’s success rate increases with each IVF cycle. Therefore, it can be said that even when the very first attempt of IVF fails, there is hope in the subsequent cycles and that the fertility treatment can yield considerable results over time.
Is IVF 100% Effective?
IVF is not 100% effective all the time. However, under certain favorable situations, IVF treatments are successful on the first attempt itself. The factors that aid the success of the IVF treatments include:
- Age of the woman, if it is below 35.
- Good ovarian reserve.
- No complaint of endometriosis, uterine fibroids, or blocked fallopian tubes.
- Healthy BMI (Body Mass Index).
- Ideal sperm quality.
Under such conditions, the IVF treatment is sure to succeed. If the treatment fails beyond these circumstances, you do not have to worry, as there is hope for the treatment to grow at the next attempt.
On average, 40% to 43% of IVF treatments are successful on a global scale. The success rate increases to 60% in the second cycle of treatment. This percentage is applicable to women below 35 years of age.
Since age impacts fertility to a greater extent for women over 35 years, the treatment’s success begins to decline with an increase in age. You can try Frozen Embryo Transfer (FET) if you are planning pregnancy at a later stage, as it will have more chances of success than fresh embryo transfer.
Why Doesn't IVF Have a 100% Success Rate?
Multiple factors influence the success of the IVF treatment. Quality of egg and sperm, successful fertilization and implantation processes, healthy lifestyle factors, and others must come into play together to yield the desired success result. When certain biological limitations, medical conditions, and other factors hinder the treatment, the desired outcome may not be produced.
Factors Affecting the Success Rate of IVF
There are several crucial factors affecting your chances of successful IVF treatment:
- Age: This is one of the most crucial factors influencing the success of IVF. Pregnancy rates are usually higher in women who are younger, as they have more and better-quality eggs.
- Egg quality: The better the quality of the eggs, the higher the chances of fertilization and the embryo developing into a healthy baby.
- Sperm quality: High sperm count, good motility, and the proper shape of the sperm are all factors that are conducive to fertilization.
- Ovarian reserve is that part of the egg weight left in the ovaries and the quality of these remaining eggs. In order for the embryo to be embedded and thrive, the uterus must be in the right state to carry it.
- The history of previous pregnancies: The past success of deliveries may have a good impact on IVF outcomes.
- Impacted by: The consumption of tobacco, abuse of alcohol, and obesity can upshot the presumed profit that comes from the rates of success of whether a woman will be able to get pregnant or not.
- Embryo quality: The grade and stage of the embryo’s development are of great significance in defining the success of implantation rates.
- Multiple Embryo Transfer: Multiple embryo transfers can increase the chances of pregnancy. But it also poses challenges to the mother and babies’ health and threatens preterm labor.
- Fertilization process: The fertilization process taking place in the laboratory distinguishes the IVF treatment. The fertilization process will take place only in favorable environments like good quality eggs and sperm, ideal temperature, proper timing, professionals’ expertise, and other factors.Â
- Implantation Process: The implantation process is crucial in IVF treatment. Only a successful implantation determines successful treatment results. Providing an optimal environment for the implantation process to take place is therefore highly essential to get positive pregnancy results.Â
- Controlled Ovarian Stimulation (COS): Controlled Ovarian Stimulation (COS) can result in Ovarian Hyperstimulation Syndrome (OHSS), which can result in blood clots, abdominal bloating, discomfort, nausea, shortness of breath, and other complicated health conditions. This can end up troubling the IVF treatment results.
- IVF protocol and technique: The skill of your fertility hospital doctor and the particular protocols followed during the procedure are important.
Success Rates of IVF by Age and Health
Age is the single most influential factor in IVF success rates. Here’s what current data shows:
- Women under 35: It is estimated that there is a 40-50% live birth rate per cycle for about half of the attempts.
- Women aged 35-37: Success rates of 30-40% are said to be the norm here.
- Women aged 38-40: On the positive side, the chances for women of this age to succeed are from 20% to 30%.
- Women over 40 are more likely to experience lower success rates since the likelihood might decrease to a minimum of 10% and the maximum would be 20%.
It’s these figures that show why personalized treatment plans are absolutely necessary. The entire article is adapted from the experience of the patient, the doctor, and the embryologist, taking into account the specific health situation, reproductive history, and details of your fertility problems, etc. to come up with the most suitable approach to help you with your family building.
Furthermore, this is just a general reminder only, and individual data surely vary based on your specific condition.
