Intracytoplasmic sperm injection (ICSI) is an assisted reproductive technique (ART) used with traditional IVF treatment in the case of severe male infertility such as oligospermia, low sperm motility and poor sperm morphology. ICSI treatment is more effective than IVF treatment for male infertility factors. 

Generally, IVF treatment is suggested for couples struggling with infertility after IUI failure. However, if the sperm of the male partner cannot fertilize the female partner’s egg naturally, then ICSI is suggested. The ICSI can overcome the limitation of IVF treatment in case of male factor infertility. For this reason, IVF-ICSI is preferred to circumvent IVF failure related to sperm issues. 

What is ICSI Treatment? 

Unlike traditional IVF treatment, in ICSI treatment, the eggs are manually inseminated by the sperm. As the name suggests, in ICSI, the sperm is artificially injected into an egg’s cytoplasm with specially designed medical equipment in the laboratory. 

How are ICSI and IVF different? And is ICSI treatment more effective than IVF treatment? 

The only difference between conventional IVF and IVF-ICSI treatment is the fertilization methods. Conventional IVF treatment uses a “natural” fertilization technique, where eggs and millions of sperm are placed in a petri dish. Then the sperm will penetrate the outer shell around the egg and fertilize it on its own. In Intracytoplasmic sperm injection, however, sperm is literally injected into an egg with the help of a microinjection pipette under a microscope, and we can call it assisted insemination fertilization. 

The ICSI treatment is more effective in terms that there will be more fertilized eggs than in a conventional IVF treatment. It is observed that, for men with severe male factor infertility, there are 60-80% chances of fertilization with ICSI compared to less than 50% chances of fertilization with only IVF. And if there are more fertilized eggs, then more quality embryos can be developed for embryo transfer. 

 This is why ICSI is commonly suggested with IVF to couples where the male partner has a severe case of infertility, and his sperm cannot fertilize the eggs by itself. 

Who Requires ICSI Treatment with IVF Treatment?

ICSI technique is used with IVF treatment in case of severe male infertility such as:

 The procedure of ICSI Treatment

The procedure of ICSI treatment is similar to IVF treatment, and the only modification is in the fertilization step. Your fertility expert will decide whether the patient needs an ICSI treatment with IVF through semen analysis of the male partner. The ICSI procedure follows as: 

Some treatments, such as PGS, might be required for embryo assessment in case of multiple IVF failures in the past.

Is there any risk of ICSI treatment?

Yes, ICSI treatment is safe. The children born through ICSI and IVF are mostly healthy. However, as the sperm is assisted in inseminating the eggs, they might be equally efficient as sperm that naturally inseminate eggs; therefore, in some rare cases, children may be born with congenital disabilities. This factor is common in IVF and ICSI.
