Intrauterine insemination (IUI) and In vitro Fertilization (IVF) are the two most common methods used for treating infertility. The main difference between IUI and IVF are:
IVF is the most successful treatment of fertility that helps couples conceive. IVF involves stimulation of eggs, retrieval of eggs, fertilization and transfer of eggs.
In an IUI method, sperms are injected into a uterus. This is done to decrease the sperms travel time to the egg.
The chances of pregnancy in an IVF treatment depends on factors such as age of the woman and the basic cause of infertility.
An IUI deposits higher count of sperms close to the eggs where the chances of eggs and sperms to unite will increase.
IVF is a little more complex and a more expensive treatment than IUI. IUI is a more shorter process. The risk of having multiple babies increases with IUI as it has more eggs for ovulation during fertilization.
The success rates of both these treatments depends on a number of factors that includes cause of infertility and age of the woman. However, studies show that the success rates of IVF are much higher than the success rates of an IUI treatment.
