The average success rate of IVF on the first attempt varies but is generally around 20-35%.On average, globally, the first IVF cycle has a 40% success rate. But don't be disheartened. As issues get identified and addressed, the potential for success in subsequent cycles, such as the second one, increases, often reaching up to 60%.Chances of success
32% for women under 35.
25% for women aged 35 to 37.
19% for women aged 38 to 39.
11% for women aged 40 to 42.
5% for women aged 43 to 44.
4% for women aged over 44.
In which cases IVF is successful : The success rates are higher in women under the age of 35 as compared to those who are above 35 undergoing the IVF treatment. If the woman has never ever conceived before and is under 35 then it is more likely for her that she would conceive in 32% of cases.
When is IVF most likely to fail
Most fertility specialists believe that in more than 95% of IVF failures it is due to arrest of the embryos. Embryonic arrest is quite often due to chromosomal or other genetic abnormalities in those embryos that made them too “weak” to continue normal development and sustained implantation.
How many rounds of IVF is normal : Over time, we've learned that couples should plan for no more than three to four IVF cycles. At that point, when IVF isn't successful, we discuss other options. This is also why you'll notice most IVF centers offer multiple-cycle discounts that run in two to four-cycle packages – keeping IVF more affordable.
Women under 38 in our IVF program have acceptable live birth rates even with only 3 – 6 eggs, do better with more than 6 eggs, and do best with more than 10 eggs. Women 38-40 and 41-42 years old have low live birth rates with low egg numbers. Success rates are much better when relatively high egg numbers are obtained. Several factors contribute to first-time IVF failure, including embryo quality, uterine receptivity, genetic abnormalities, and lifestyle factors. The timing of embryo transfer, ovarian response, and the presence of underlying health conditions all play a role in influencing the outcome of the initial IVF attempt.
Why does IVF fail the first time
Several factors contribute to first-time IVF failure, including embryo quality, uterine receptivity, genetic abnormalities, and lifestyle factors. The timing of embryo transfer, ovarian response, and the presence of underlying health conditions all play a role in influencing the outcome of the initial IVF attempt.Risks
Stress. IVF can be draining for the body, mind and finances.
Complications from the procedure to retrieve eggs.
Ovarian hyperstimulation syndrome.
Miscarriage.
Ectopic pregnancy.
Multiple pregnancy.
Birth defects.
Premature delivery and low birth weight.
Despite the complexity of the IVF process, one of the most common causes of failed IVF cycle is an embryo that failed to implant on the lining of the uterus. The embryo may be incapable of attaching properly, or it may have been transferred to the uterus and the lining is not compatible with it. Over time, we've learned that couples should plan for no more than three to four IVF cycles. At that point, when IVF isn't successful, we discuss other options. This is also why you'll notice most IVF centers offer multiple-cycle discounts that run in two to four-cycle packages – keeping IVF more affordable.
Is 4 eggs OK for IVF : Women under 38 in our IVF program have acceptable live birth rates even with only 3 – 6 eggs, do better with more than 6 eggs, and do best with more than 10 eggs. Women 38-40 and 41-42 years old have low live birth rates with low egg numbers. Success rates are much better when relatively high egg numbers are obtained.
Are 5 eggs enough for IVF : For women with 1–4 eggs at retrieval it was 30.8% and for 5–9 eggs it was 36.2%. In women age 35–39 (n=543), optimal pregnancy rates (34.8%) were achieved with 5–9 eggs at retrieval. Less than 5 eggs significantly reduced the pregnancy rate (15.6%) whereas more than 10 eggs yielded pregnancy rates between 28 and 29%.
What is the biggest problem with IVF
Poor quality of the egg and embryo is one of the leading causes of IVF failure. Although current technology allows doctors to screen for aneuploidy, it cannot detect every genetic disease. Therefore, good stimulation protocols, embryology lab quality, and ET techniques are essential to the success of IVF. The standard spacing between IVF cycles is around four to six weeks after a negative pregnancy test. Basically, it is ideal to wait until the patient has gone through at least one full menstrual cycle before starting another round of IVF.Conceiving with IVF does carry an increased risk of pregnancy complications. In particular, there is an increased risk of preterm birth, low birth weight, hypertension, maternal gestational diabetes, and placental complications⁷.
What is the main reason IVF fails : IVF can fail due to embryos that have chromosomal abnormalities. This means that the embryo has a missing, extra, or irregular portion of chromosomal DNA. The body then rejects the embryo and this results in IVF failure.
