Intrauterine insemination (IUI)
Intrauterine insemination (IUI), a form of artificial insemination, is a relatively simple procedure that enables conception by directing sperm to the right place at the right time. In this process, a thin tube called a catheter is placed directly into the cervix, and a carefully prepared sperm sample is injected directly through the catheter into the uterus.
IUI increases a woman's chances of becoming pregnant by injecting an optimal sperm sample directly into the uterus at a time when the woman is most fertile. Studies have shown that pregnancy is more likely to occur if timing of exposure to sperm is controlled in this way, and if sperm is placed in higher numbers closer to the egg or eggs. Fertility medication is often recommended for those diagnosed with age-related sub-fertility, endometriosis, unexplained infertility or male factor infertility.
