Intrauterine Insemination (IUI) is a fertility treatment that involves placing sperm inside a woman’s uterus to facilitate fertilization. The goal of IUI is to increase the number of sperm that reach the fallopian tubes and subsequently increase the chance of fertilization.Placing the Sperm

This process occurs when a very thin elastic catheter is inserted through the cervix and washed sperm is injected into the uterus.

The biggest percentage of  women consider IUI to be painless, along the same lines as having a pap smear. There can be some cramping afterward, but often what is felt is ovulation-related rather than from the IUI. The catheter often isn’t felt because the cervix is already slightly open for ovulation.We will  give you instructions on how long beforehand and afterwards to abstain from intercourse, and any resting periods after the IUI.


Ideally an IUI should be performed within 6 hours either side of ovulation (for male factor infertility, some doctors believe after ovulation is better) with the sperm waiting for the egg. When timing is based on an hCG injection, the IUIs are usually done between 24 and 48 hours later. Typical timing would be to have a single IUI at about 36 hours post-hCG. If two IUIs are scheduled, they are usually spaced at least 12 hours apart between 24 and 48 hours after the hCG.

If no use of drugs is done, then doctors will base timing of IUI on a natural LH surge. In that case, a single IUI at 36 hours is the norm, but doing them at 24 hours is also quite common.
