Frequently Asked Questions About ICSI
ICSI is a sophisticated form of IVF where individual sperm are selected for injection directly into the egg to improve the chances of fertilisation and creating an embryo. ICSI is used in cases where there are problems with sperm quality or quantity.
In vitro fertilisation is fertilisation outside the body. During IVF, sperm and eggs are brought together in a specialised laboratory to create an embryo. As part of the IVF process, drugs are used to stimulate the ovaries to prepare eggs for fertilisation.
These eggs are then collected usually under a general anaesthetic and combined with sperm to allow the eggs to be fertilised. The eggs that are fertilised successfully are grown and monitored in the lab for 2-6 days before the best one, two or in exceptional cases three embryos are transferred back into the womb to grow into a baby.
In some cases, IVF or ICSI is the only option. In others it is one of many options. Health NCY recommended specialists will be able to advise you on the best course of treatment depending on your individual circumstances, including diagnosis, age and length of time you’ve been trying to conceive.
In some IVF/ICSI cycles, several embryos are produced. Whilst three of them are transferred to the women’s uterus, remaining good quality embryos can be frozen for the future use. Embryo freezing is a well-developed technique today that allows women to have another chance of pregnancy. Embryo freezing is cheaper than the regular cycle because no medication is used and no anaesthesia is required. Embryos can be frozen for several years and used in the future if the couple desires another child or if the first cycle is unsuccessful.
