Intra cytoplasmic sperm injection (ICSI)
What is ICSI treatment?
Intracytoplasmic injection or ICSI, involves the injection of a single sperm into a mature egg.
In traditional IVF, 1 egg and up to 100,000 sperm are placed in a petri dish. Fertilisation is achieved by natural processes involving changes to both sperm and egg.
Dr Tamara Hunter: What is ICSI?
Who is ICSI for?
ICSI is primarily used for couples where the chances of fertilisation with IVF are low due to poor quality sperm. It is also used for testicular sperm, poor quality sperm post freezing, or reduced or failed fertilisation in a previous IVF cycle.
"ICSI is a great option if the sperm has reduced motility or if the man has a low sperm count. We prepare the semen sample and choose a healthy looking sperm for injection. This process increases the likelihood of fertilisation being achieved."
IVF vs ICSI
How is ICSI done?
The woman takes hormones to stimulate the follicles within the ovaries. Her cycle is tracked with ultrasound scans and blood tests.
Egg collectionWe collect eggs from the ovarian follicles.
ICSIA sperm is selected and drawn into a very fine glass pipette. It is then injected into each individual egg.
Embryo developmentOver the next few days, the embryos develop through to the blastocyst stage.
The male has reduced sperm count or if he cannot ejaculate
After a vasectomy
The sperm has reduced motility
What are the risks with ICSI?
The rate of birth defects does not seem to differ between ICSI and IVF treatments. As with any type or ART treatment, this procedure may increase your risk of a multiple pregnancy.
