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.
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:
