Intracytoplasmic Sperm Injection (ICSI)

ICSI has revolutionised the treatment of male infertility. Prior to the first successful ICSI pregnancy in 1992, very little could be offered to couples with severe male factor infertility aside from using donor sperm.

How ICSI Works

Male infertility issues contribute to approximately 50% of infertile couples. Sperm problems include low count, reduced movement (motility), abnormally shaped sperm, and antibodies that make sperm clump together.

While IVF depends on adequate numbers of motile sperm capable of penetrating an egg, ICSI is used as an alternative when insufficient quality or numbers of sperm are present.

The ICSI procedure requires great technical skill in selecting an individual sperm and injecting it into an egg without damage. Once injected, the eggs are cultured in the same way as IVF-generated embryos.

When ICSI is Recommended

Low sperm count
Reduced sperm movement (motility)
Abnormally shaped sperm
Sperm antibodies causing clumping
Previous failed IVF fertilisation
Use of surgically retrieved sperm

Advantages of ICSI

High fertilisation rates even with poor sperm quality
Can use sperm that cannot fertilise naturally
Suitable for surgically retrieved sperm
Enables genetic testing of embryos
Similar success rates to IVF for embryo development

Blastocyst Culture

A blastocyst is an embryo grown for 5-6 days after fertilisation, consisting of more than 100 cells with differentiated functions.

By growing embryos to day 5 in modern media, we can choose the embryo most likely to result in a pregnancy. Many embryos fail to develop beyond day 3, so blastocyst culture helps identify the most viable embryos.

If fertilisation can be achieved by conventional IVF, doing ICSI will not improve the chance of having a baby.
