ICSI pregnancy 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.In another word, he success rates for two common fertility treatments have peaked, with only one in four attempts resulting in pregnancy. The success rate for IVF and a similar technique called intracytoplasmic sperm injection (ICSI) have been around this level for about a decade.

In the new figures, which come from national registries in 36 European countries, 27 per cent of women became pregnant from a round of IVF. For ICSI, which involves injecting a sperm into an egg, the pregnancy rate was 24 per cent, and this has actually slightly fallen from 30 per cent in 2008. The results were presented at the European Society of Human Reproduction and Embryology (ESHRE) meeting in Vienna.

ICSI was designed to help men with problems with their sperm, by putting one sperm directly into an egg, but as ICSI treatment cycles now outnumber those of IVF by around three to one, that suggests it is being used for other causes of infertility, says Christian de Geyter, chair of ESHRE’s European IVF Monitoring Consortium. Some believe ICSI is more successful, but the latest figures, which were for 2016, don’t support that, although only a randomised trial can find out for sure.

ICSI Benefits

Intracytoplasmic sperm injection offers you and your partner a chance to have a baby, even with severe male infertility issues. ICSI benefits include helping you get pregnant even if you are dealing with one or more of the following conditions:

Low sperm count
Physical blockage
Poor sperm motility (movement) or morphology (shape)
Having tried IVF without success
Desire for pregnancy post-vasectomy

10 common questions about ICSI pregnancy success rate

1Is 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.

2What 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

3How 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.

4Does ICSI increase chance of having a girl?

Fertilization rates with ICSI range from 50 to 80 percent. However, not all fertilized eggs develop into healthy embryos. ... Since ICSI takes place as part of the IVF process, there is an increased chance of becoming pregnant with multiples for couples that try ICSI.

5Are ICSI babies normal?

IVF, ICSI Babies as Healthy as Others. July 2, 2003 -- Babies born with the assistance of the infertility treatments in vitro fertilization (IVF) and intracytoplasmic sperm injection (ICSI) don't face any more health problems than babies conceived by natural means, according to the longest-running study to date.

6Does 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

7Does 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

8How 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 .

9Is ICSI Safe?

Is It Safe for the Baby? ICSI-IVF comes with all the risks of a regular IVF cycle, but the ICSI procedure does introduce additional ones. A normal pregnancy comes with a 1.5 to 3 percent risk of major birth defect. ICSI treatment carries a slightly increased risk of birth defects, but it's still rare

10Is ICSI more expensive than IVF?

However, ICSI is also increasingly used in patients without male factor infertility where the procedure has not been shown to improve clinical outcomes. ... ICSI also adds to the cost of an IVF cycle, making it more expensive than conventional IVF
