ICSI Success Rate
Success Rate
The ICSI procedure fertilizes 50 to 80 percent of eggs. You might assume all eggs get fertilized with ICSI-IVF, but they don’t. Fertilization isn’t guaranteed even when a sperm is injected into the egg.
Remember that fertilization rates don’t tell you the clinical pregnancy or live birth rates. Once fertilization happens, the success rate for a couple using ICSI with IVF is the same as a couple using regular IVF treatment.
Can ICSI affect a baby’s development?
If a woman gets pregnant naturally, there is a 1.5% to 3% chance that the baby will have a major birth defect. The chance of birth defects associated with ICSI is similar to IVF, but slightly higher than in natural conception.
The slightly higher risk of birth defects may actually be due to the infertility and not the treatments used to overcome the infertility.
Certain conditions have been associated with the use of ICSI, such as Beckwith-Wiedemann syndrome, Angelman syndrome, hypospadias, or sex chromosome abnormalities. They are thought to occur in far less than 1% of children conceived using this technique.
Some of the problems that cause infertility may be genetic. For example, male children conceived with the use of ICSI may have the same infertility issues as their fathers.
Will ICSI work?
ICSI fertilizes 50% to 80% of eggs. But the following problems may occur during or after the ICSI process:
. Some or all of the eggs may be damaged.
. The egg might not grow into an embryo even after it is injected with sperm.
. The embryo may stop growing.
Once fertilization takes place, a couple’s chance of giving birth to a single baby, twins, or triplets is the same if they have IVF with or without ICSI.

Is ICSI more successful than IVF?
Is ICSI better than IVF? It depends. Research shows that IVF is just as effective as the ICSI procedure, where sperm is injected directly into an egg, when there is no male infertility factor. Cumulative live birth rates in Victoria were similar for IVF and ICSI in these circumstances.
What is the success rate of ICSI?
The most important indicator of ICSI success appears to be the fertilization rate achieved with the ICSI procedure. The fertilization rate in the UCSF IVF laboratory is exceptional — currently 80 to 85 percent. That is to say, on average, eight out of every 10 eggs will fertilize normally
What percentage of eggs fertilize with ICSI?
The ICSI procedure fertilizes 50 to 80 percent of eggs.
How effective is ICSI?
Fertilization rates for ICSI: Most IVF programs see that about 70-85% of eggs injected using ICSI become fertilized. We call this the fertilization rate, which is different from the pregnancy success rate. … In such cases, ICSI fertilization and pregnancy success rates tend to be lower
Can you have twins with ICSI?
Fertilization rates with ICSI range from 50 to 80 percent. However, not all fertilized eggs develop into healthy embryos. … Couples that use ICSI with IVF have about a 30 to 35 percent chance for twins and a 5 to 10 percent chance for having triplets or more
Are ICSI babies normal?
IVF, ICSI Babies as Healthy as Others.

Does ICSI increase chance of having a girl?
Australian researchers found the odds of a boy went up from 51 in 100 when conceived naturally to 56 in 100. But another assisted reproduction technique called ICSI, which singles out the sperm that will fertilise the IVF egg, makes a girl more likely
Does ICSI damage the egg?
Egg Damage The most immediate concern with ICSI is that in the process of trying to fertilize an egg, some eggs will be damaged. Today, good labs manage to achieve fertilization in 70 – 80% of eggs inseminated with ICSI, and likely about 5% of good quality eggs will be damaged in the process.
How long does it take to get pregnant with ICSI?
One cycle of ICSI takes between four weeks and six weeks to complete. You and your partner can expect to spend a half-day at the clinic for the egg and sperm retrieval procedures. You will usually be asked to go back between two days and five days later for the embryo transfer procedure
Does ICSI cause birth defects?
The incidence of genitourinary tract abnormalities is statistically significantly increased in children conceived by IVF/ICSI. The findings are consistent with other studies that suggest that patients with subfertility are at higher risk of having a child born with congenital abnormalities.

What is the average fertilization rate with ICSI?
The ICSI procedure fertilizes 50 to 80 percent of eggs. You might assume all eggs get fertilized with ICSI-IVF, but they don’t. Fertilization isn’t guaranteed even when a sperm is injected into the egg
New Scientist reports that a recent study revealed that ICSI boasts a pregnancy success rate of 24%. While IVF without ICSI still has a slightly higher pregnancy success rate at 27%, those aren’t bad odds for anyone who’s already tried other methods of assisted reproductive technology
Fertilization rates for ICSI: Most IVF programs see that about 70-85% of eggs injected using ICSI become fertilized. We call this the fertilization rate, which is different from the pregnancy success rate.
Pregnancy success rates for in vitro fertilization procedures with ICSI have been shown in some studies to be higher than for IVF without ICSI. This is because in many of the cases needing ICSI the female is relatively young and fertile (good egg quantity and quality) as compared to some of the women having IVF for other reasons.
In other words, the average egg quantity and quality tends to be better in ICSI cases (male factor cases) because it is less likely that there is a problem with the eggs – as compared to cases with unexplained infertility. Some unexplained cases have reduced egg quantity and/or quality – which lowers the chances for a successful IVF outcome.
IVF with ICSI success rates vary according to the specifics of the individual case, the ICSI technique used, the skill of the individual performing the procedure, the overall quality of the laboratory, the quality of the eggs, and the embryo transfer skills of the infertility specialist physician.
Sometimes IVF with ICSI is done for “egg factor” cases – low ovarian reserve situations. This is when there is either a low number, or low “quality”of eggs (or both). In such cases, ICSI fertilization and pregnancy success rates tend to be lower.
This is because the main determinant of IVF success is the quality of the embryos.
The quality of the eggs is a crucial factor determining quality and viability of embryos.
In some cases, assisted hatching is done on the embryos prior to transfer, in order to maximize chances for pregnancy.
