Struggling with low sperm count or poor sperm motility? Discover how ICSI treatment can help you become a father

If you’ve got a low sperm count, poor sperm motility, or male infertility issues, did you know there’s a specialist fertility treatment designed to help you father a baby?

It’s called ICSI (Intracytoplasmic Sperm Injection) - a highly effective male fertility treatment. Although it may sound complex, the procedure is carried out in a laboratory and does not require surgery on the male partner.

Here’s everything you need to know about sperm problems, ICSI treatment, and male fertility support:

What is ICSI, and how is it performed?

ICSI treatment is similar to IVF (In Vitro Fertilisation), but with one key difference. Instead of mixing sperm with eggs for natural fertilisation, a single healthy sperm is carefully selected and injected directly into an egg in a laboratory setting.

This advanced fertility technique increases the chances of fertilisation, especially in cases of male infertility.

How does ICSI help with male infertility?

ICSI is recommended when sperm are unable to reach or penetrate the egg naturally. It is commonly used for:

  • Low sperm count (oligospermia)
  • Poor sperm motility (asthenozoospermia)
  • Abnormal sperm morphology
  • High sperm DNA fragmentation, a hidden cause of infertility and miscarriage

By overcoming these barriers, ICSI significantly improves fertilisation outcomes.

How is sperm selected for ICSI?

At our specialist fertility clinic, our experienced embryologists use advanced microscopic techniques to identify the highest-quality sperm.

We assess:

  • Sperm shape (morphology)
  • Movement (motility)
  • Overall sperm health

This ensures the best possible chance of successful fertilisation and embryo development.

What are the success rates of ICSI?

ICSI is one of the most effective treatments for male infertility. On average, around one in three patients successfully achieve a pregnancy and have a baby using ICSI.

Success rates can vary depending on age, underlying fertility issues, and overall health.

Can ICSI help if both partners have fertility problems?

Yes. ICSI is often recommended when both male and female infertility factors are present.

For example, if your partner has:

  • Blocked fallopian tubes
  • Pelvic scarring or adhesions

…and you have a low sperm count or sperm quality issues, ICSI can significantly improve your chances of conception.

If there are no male fertility issues, IVF treatment may be recommended instead.

Personalised fertility treatment plans

We always recommend the most suitable fertility treatment based on your individual diagnosis, test results, and medical history - giving you the best possible chance of having a baby.
