Egg retrieval — when the eggs are mature, they are retrieved while the woman is under light anaesthetic. Embryo development — when using IVF, sperm from the male partner or a donor are added to the eggs to allow them to be fertilised. When using ICSI, the scientist picks up a single sperm and injects it into each egg using a microscopic needle.
The eggs and sperm are then kept in the laboratory for 2 to 5 days depending on clinic practice for embryos to develop.
The eggs are then mixed with sperm in a laboratory dish, and checked after hours to see if the sperm have naturally fertilised any eggs. If the treatment has worked, the fertilised eggs will develop in the laboratory for a further two to five days before being transferred into the womb. A pregnancy test can be taken two weeks after the egg collection to check if the IVF treatment has succeeded and implantation has taken place.
When the eggs arrive in the laboratory, fertilisation is attempted by injecting a single active normal-looking sperm, picked up under the microscope, into each egg using a very fine needle. The fertilised egg is then transferred to the womb and the success can be determined with a pregnancy test after two weeks. The treatment was developed by British nurse Jean Purdy, physiologist Robert Edwards and obstetrician and gynaecologist Patrick Steptoe.
The method began to be used in Australia and the US, and was further refined to allow the conversion of IVF from a research tool to a treatment offered in fertility clinics. The first successful birth using ICSI was recorded in and the treatment was carried out by Gianpiero Palermo after researching and developing the treatment at the Vrije Universiteit Brussel.

IVF — In-Vitro Fertilisation - involves the use of fertility drugs to gently stimulate your ovaries to produce quality mature eggs, which are retrieved and then fertilised in our laboratory with sperm from either your partner or a donor.
Sperm and eggs are placed together in a special dish and eggs monitored for signs of fertilisation. IVF allows us to maximise the chance of fertilisation by placing eggs with sperm.
We can choose the embryo with the highest potential for pregnancy thanks to our advanced embryo selection techniques, which include time-lapse monitoring and Preimplantation Genetic Screening. If you have more than one good embryo from your cycle, you can freeze the remainder to use in future treatment cycles. IVF is designed to overcome issues that prevent sperm from fertilising an egg in the body, such as fallopian tube damage or blockages.
It may also be advised in some cases of unexplained infertility, or in mild cases of male infertility. Instead of sperm being mixed with the egg in the laboratory, the best single, healthy sperm is extracted from the sample and injected directly into the egg to fertilise it. ICSI helps you get pregnant when your partner has sperm problems. Because the sperm is injected it bypasses the other stages of early fertilisation.
Only the best quality sperm is used for fertilisation, as identified by one of our Embryologists. ICSI is a treatment designed to overcome male fertility issues , such as low sperm count or poor sperm mobility, which prevents sperm from fertilising the egg naturally. IUI is short for Intrauterine Insemination.
