Intra Uterine Insemination (IUI)

IUI is a treatment where the semen which has been prepared in the laboratory is inserted via a fine tube directly into the uterine cavity at the time of ovulation to maximize the chance of conception. Only the actively motile sperm are inserted and the cervical mucus is bypassed.


Ultrasound examination of the ovaries will reveal when ovulation is likely to occur. This is followed by an injection to bring on ovulation, or with urine testing of LH hormone levels to detect the natural surge of this hormone that accompanies ovulation.


You should abstain from intercourse for 2 – 3 days (a maximum of five days) prior to expected ovulation. This date (or day of your cycle) will be estimated when we see you to plan your treatment.


Prior to this treatment cycle, tests may have been performed to rule out abnormalities of the female reproductive system, such as tubal blockage.


The male partner will also have had his semen analysed to ensure the correct parameters are present allowing conception using IUI methods. Low sperm counts normally contraindicate IUI.


A serum progesterone may be carried out one week after ovulation, to confirm that an egg was released.


If you are not pregnant from any given cycle of treatment, you can expect a period within 14 days of treatment following IUI.


The success rate is dependant on the infertility cause and the female’s age.
