Intrauterine Insemination (IUI) is the simplest of the Assisted Reproductive Technology techniques and consists of placing the sperm inside the uterus through a small catheter.
In the IUI cycle, a controlled induction of ovulation is performed through oral or injectable medication. The sperm is prepared in the laboratory, allowing to select the best sperm that is placed inside the uterus at the time of ovulation.
It is indicated in couples who presents male light infertility, incompatibility between the cervical- mucus and the sperm and in situations with no apparent cause.
It is also the first-line technique when it is necessary to resort to donor sperm in women with permeable tubes.
