The insemination procedure involves direct placing of washed and prepared sperm inside the cavity of the womb in a natural cycle around the time of ovulation.

The insemination can be performed in a stimulated cycle. The intrauterine insemination with ovarian stimulation results in higher success rates than IUI only.

The male partner is asked to produce a semen sample by masturbation. Only washed and prepared sperm are used for IUI.

The prepared sperm is then injected into the cavity of the womb using a fine plastic catheter. IUI is a relatively painless procedure.
