What is intracytoplasmic sperm injection (ICSI)?
Intracytoplasmic sperm injection (ICSI) is a form of IVF treatment that involves injecting a single sperm into each egg using very fine micromanipulation equipment.
As the human egg is one-tenth of a millimetre in diameter and the sperm 100 times smaller this is a very delicate procedure performed by highly skilled embryologists using a sophisticated microscope.
Who may require ICSI?
For many couples where sperm quality is poor, conventional IVF is unlikely to result in fertilisation. In such cases your fertility specialist will recommend IVF with ICSI. ICSI is also used where sperm have been obtained directly from the testis, for example after vasectomy reversal or in cases of absent vas deferens.
ICSI has not been shown to increase fertilisation rates in situations where the sperm assessment is normal. Normal fertilisation rates with IVF or ICSI are approximately 50-60%. That is, for every 10 mature eggs obtained and combined with the sperm either with IVF or ICSI, approximately five to six will fertilise normally.
If there is evidence of poor outcomes with previous ICSI treatment, your Melbourne IVF fertility specialist may recommend you undergo Intracytoplasmic morphologically selected sperm injection (IMSI) to improve your chances of pregnancy success.
How ICSI works
What does ICSI treatment cost?
When comparing costs between clinics it is important that you check which costs are included as there may be additional fees charged by your treating fertility specialist during your cycle, and there will be costs associated with private hospital and anaesthetist fees.
