Intracytoplasmic sperm injection (ICSI) treatment

ICSI is an extra procedure carried out during IVF treatment, where a single sperm is injected directly into an egg to help maximise the chances of fertilisation.

For 30 years, we’ve successfully used ICSI to overcome fertility challenges.

What is ICSI?

For around a third of couples finding it hard to get pregnant, the cause of infertility is sperm related.

ICSI is a common treatment used in this situation.

Around 2 in 3 IVF cycles use ICSI.

During a regular IVF cycle, mature eggs are removed from the ovaries, mixed with sperm in a lab, and left to fertilise.

In ICSI, an embryologist injects a single sperm into each egg to fertilise it.

This can increase the chance of fertilisation as the sperm no longer has the challenge of getting into the egg.

Who can benefit from ICSI treatment?

ICSI treatment could help you if:

  • You’re unable to conceive because of fertility problems

  • You’ve already had IVF or another fertility treatment that didn't work

When is ICSI recommended?

During your consultation, we’ll run a series of tests to understand the cause of your fertility issues and may recommend ICSI if:

  • You have a low sperm count

  • Your sperm don’t move normally or are abnormally shaped

  • You’re using sperm recovered via surgical sperm retrieval

  • Your sperm have high levels of DNA damage

  • You’ve had IVF previously and none or very few eggs fertilised

  • You’re using donor eggs

  • You’re using frozen eggs or sperm

Occasionally, we may recommend ICSI to you even if you have no specific sperm problems.

This is because research has shown that ICSI can help improve success rates where previous rounds of IVF haven’t worked.

What are ICSI success rates?

ICSI treatment is very effective, resulting in fertilised embryos in between 50% and 80% of cases.

However, following ICSI there are many other factors within the IVF process that affect the chance of becoming pregnant.

Age is one of the main factors. For women aged up to 30, the pregnancy success rate following ICSI treatment is around 40%.

For women aged 30 to 39, it's 30-35%.

ICSI in more detail

ICSI follows the exact same process as a typical IVF cycle. It's only the way the egg is fertilised that changes.

A sperm sample is taken close to the time of egg retrieval.

This sample is washed and prepared in a laboratory, and our specialist embryo team select the healthiest sperm.

Looking through a microscope, an embryologist injects an individual sperm into each egg using a glass tube called a cannula.

The fertilised eggs are incubated for up to six days, and the best embryo is then carefully selected and placed into the womb to develop.

Any remaining embryos can be frozen for potential use in the future.
