For cycles without male factor infertility, ICSI use increased from Similar increases were found for selected non-male factor infertility indications, including unexplained infertility, maternal age 38 years or older, low oocyte yield, having 2 or more prior assisted reproductive technology cycles and no prior live births, and use of preimplantation genetic testing.
ICSI use also increased in the absence of any of these indications, suggesting that other reasons may be influencing the clinical decision to use ICSI. For cycles with a diagnosis of male factor infertility, the likelihood of cycle cancellation between egg retrieval and embryo transfer a surrogate measure of failed fertilization was markedly decreased for cycles where ICSI was used, compared with those using conventional IVF, confirming that ICSI increases the chances of fertilization for couples with male factor infertility.
There was no difference in cycle cancellation for couples without male factor infertility. For cycles with a male factor infertility diagnosis, ICSI use was associated with reduced rates of implantation and multiple births, compared with conventional IVF. For cycles without male factor infertility, ICSI use was associated with decreased rates of implantation, pregnancy, live birth, and multiple live births compared with conventional IVF. More about these findings Overall, use of ICSI did not improve reproductive outcomes, regardless of whether male factor infertility was present.
This may be due to poorer quality embryos resulting from cycles where ICSI was used because the procedure bypasses natural barriers to fertilization. Select personalised ads.

ICSI-IVF is a specialized form of in vitro fertilization that is used mostly commonly in cases of severe male infertility , after repeated failed fertilization attempts with conventional IVF, or after egg freezing oocyte preservation.
It's also very commonly used for preimplantation genetic testing, or PGT testing. In fact, most clinics require it if you are doing PGT testing. The concept behind this stipulation is that with conventional insemination, all of the sperm attempting to fertilize an egg can potentially fray the lining of the embryo and give inaccurate PGT results.
During regular IVF, many sperm are placed together with an egg, in hopes that one of the sperm will enter and fertilize the egg on its own. Others reserve the treatment for those with severe male infertility or another medically indicated reason. With that said, ICSI-IVF has enabled many infertile couples to get pregnant when, without it, they would not have been able to conceive using their own eggs and sperm.
If a man does not have any sperm in his ejaculate, but he is producing sperm, they may be retrieved through testicular sperm extraction or TESE. ICSI is also used in cases of retrograde ejaculation if the sperm are retrieved from the man's urine. As with regular IVF, you'll take ovarian stimulating drugs , and your doctor will monitor your progress with blood tests and ultrasounds. Once you've grown enough good-sized follicles , you'll have the egg retrieval , where eggs are removed from your ovaries with a specialized, ultrasound-guided needle.
Your partner will provide their sperm sample that same day unless you're using a sperm donor or previously frozen sperm. Once the eggs are retrieved, an embryologist will place the eggs in a special culture and using a microscope and tiny needle, a single sperm will be injected into an egg.
This will be done for each egg retrieved. By injecting the sperm directly into the egg, the chance of a successful fertilization is greatly increased. This also increases the success rate. Even when the sperm is directly injected into the egg, it may not fertilize the egg. Once the egg is fertilized, it must then attach itself to the uterine lining and develop into a fetus. Couples are usually advised to undergo this procedure only if:.
Couples are usually advised to undergo this procedure only if: They have had at least one unsuccessful IVF cycle The man has a very low sperm count.
This is usually seen after a vasectomy reversal or in the case of a blockage in the vas deferens. It may also be performed if frozen sperm is being used for the IVF cycle.
