What are the differences between IVF and IUI.
IUI stands for intrauterine insemination and involves the insertion of processed and concentrated motile sperm directly into the uterus. The process is performed one or two times in the days after ovulation. IVF involves the stimulation of the ovaries to produce multiple eggs, then the removal of these eggs and their fertilisation in vitro, and the fertilised embryos being placed in the uterus. In IVF, medication is given to develop multiple eggs (ideally around 15). In IUI, a woman will only develop one or two eggs.
IUI combats infertility by giving medication if needed to ensure one or two eggs are provided, and placing the sperm near their target. IVF uses ICSI (intracytoplasmic sperm injection) to inject sperm straight into an egg, meaning only one healthy sperm is needed. Egg quality is also likely to be good due to medications provided. Genetic testing can be used to reduce the risk of miscarriage.
