Intrauterine insemination (IUI)

Intrauterine insemination (IUI) places prepared sperm inside the uterus around ovulation to help fertilisation happen naturally.

IUI (intrauterine insemination) is a fertility treatment in which a sperm sample is washed and concentrated in the laboratory, then placed inside the uterus with a thin, soft catheter at the time of ovulation. This shortens the sperm's journey to the egg and helps fertilisation happen naturally.

IUI may suit couples with mild male-factor infertility, unexplained infertility, cervical mucus problems, or ovulation disorders such as PCOS, provided the fallopian tubes are open.

You may take mild ovulation-stimulating medication, and we monitor your follicles by ultrasound. On the right day, the prepared sample is placed in the uterus. You can usually resume normal activities soon after, and take a pregnancy test about two weeks later.

• Is IUI painful?

  Most women feel mild cramping at most, similar to a routine smear test. It usually takes only a few minutes and needs no anaesthetic.

• How many IUI cycles should I try?

  It depends on your age and diagnosis. Many doctors suggest a limited number of IUI cycles, often around three to four, before considering IVF. Your specialist will guide you.

• What is the difference between IUI and IVF?

  With IUI, fertilisation happens inside the body. With IVF, eggs are fertilised in the laboratory and an embryo is transferred to the womb. IUI is less invasive, while IVF is usually recommended for more complex cases.

• Does IUI guarantee pregnancy?

  No. The chance per cycle is generally lower than with IVF and depends on age and diagnosis. We'll give you a clear, honest outlook.
