Intrauterine Insemination
Often used as one of the initial fertility treatment options, intrauterine insemination (IUI) involves placing prepared sperm directly into the uterus around the time of ovulation to facilitate fertilisation.
Before proceeding with IUI, your fertility specialist may suggest a diagnostic test called a hysterosalpingogram (HSG) to check for any blockages or structural abnormalities in the uterus or fallopian tubes. The procedure involves injecting a medical-grade dye into the uterus and viewing it under X-ray or ultrasound to assess whether the fallopian tubes are open and the uterine cavity appears normal.

The IUI Process
Ultrasound scans and blood tests are used to track ovulation. In some cases, medication may be prescribed to stimulate egg growth.
A sperm sample is processed in the laboratory to concentrate motile sperm.
The prepared sperm is placed directly into the uterus using a thin catheter. The procedure is generally brief and well tolerated.
Fertilisation takes place naturally inside the body. Around two weeks later, a blood test is performed to determine whether conception has occurred.
Will I Need IUI?
Your doctor may suggest IUI if:
- You have unexplained infertility.
- There are mild male fertility factors, such as slightly low sperm count or motility.
- You have ovulation problems that can be managed with medication.
IUI may not be suitable if the fallopian tubes are blocked, if there are significant sperm issues, or if other treatment approaches are being considered.
Your specialist will assess your medical history and test results to determine whether IUI may be appropriate for you.
Common Questions
An IUI cycle usually takes about 2–3 weeks, depending on ovulation timing and whether medication is used.
Most individuals experience little discomfort during IUI, though mild cramping similar to menstrual pain can occur.
The number of IUI cycles needed varies for each person. Your doctor will review results after each cycle and discuss appropriate next steps.
Donor sperm may be used for IUI in specific clinical situations, based on medical assessment and regulatory guidelines.
IUI is generally considered a low-risk procedure. The main potential risk is a higher chance of multiple pregnancy when ovulation-inducing medication is used.
