This less invasive alternative to IVF may be an option for couples and solo mothers preferring a more natural approach to assisted reproduction.
For heterosexual couples facing infertility, solo mothers, and same-sex female couples, IUI gives nature an opportunity to play a greater role while still improving your chances of conceiving.
Intrauterine insemination is an assisted reproductive technology that involves depositing the sperm of the male partner or donor directly into the uterus of the female partner. The sperm then must swim to the fallopian tubes and fertilise the waiting egg, which then implants in the lining of the uterus for a pregnancy to take place.
Compared to in vitro fertilisation (IVF) and intracytoplasmic sperm injection (ICSI) , IUI is seen as a more natural and less invasive approach to assisted conception, making it a valuable alternative for those who personally prefer this. There is less intervention required from your fertility specialist and embryologists, and nature and chance play a more significant part in the outcome.
If you are in a relationship and have been trying to conceive without success for 12 months or more (or for six months or more if the female partner is aged over 35), undertaking a comprehensive fertility assessment with Dr Alice Huang can help to determine whether IUI may be an appropriate option for you. You may consider IUI if you want to prioritise a less invasive fertility treatment or prefer to start with a more economical treatment option.
IUI is also used in some cases of assisted reproduction using frozen sperm, whether from a donor or the male partner. Same-sex female couples or single women utilising donor sperm may have the option of IUI or IVF/ICSI, depending on the condition of the sperm. In these cases, IUI is often referred to as donor insemination.
Whatever your circumstances, Dr Huang will advise you if your situation is suitable for IUI or whether a more precise and controlled treatment such as IVF with or without ICSI will be a more appropriate option.
Preimplantation genetic testing (PGT) is an optional genetic analysis performed on embryos that have been developed in vitro (meaning outside the body). As intrauterine insemination results in fertilisation and embryo development inside the body, PGT cannot be offered if you are undergoing IUI.
IVF/ICSI with PGT may be considered instead of IUI in some situations where there is an increased risk of passing on a genetic condition to a child, including when one or both partners are known to carry a specific genetic variant. Reproductive genetic carrier screening (RGCS) is an optional screening test that is available to individuals or couples planning pregnancy, regardless of family history. It can identify whether you carry certain genetic variants, even if you are healthy yourself. If you have a known family history of a genetic condition, more specific genetic testing and genetic counselling may be recommended rather than screening alone. RGCS is commonly undertaken before pregnancy, although timing may vary depending on individual circumstances.
Dr Huang carefully monitors each treatment cycle to determine the most appropriate timing for insemination. This usually involves ultrasound scans, blood tests, and often medication to support follicle development and ovulation, including for those with otherwise regular cycles. If your cycles are irregular or ovulation is less predictable, ovulation induction may also be recommended. Accurate monitoring helps ensure treatment is timed as precisely as possible.
On the day of insemination, a fresh sperm sample is usually collected from your partner and processed in the laboratory to select and concentrate the healthiest motile sperm. If frozen donor sperm is being used, or if your partner’s sperm sample was collected and frozen earlier, it will be thawed and prepared on the day of treatment.
The insemination procedure is quick and straightforward. You will be asked to lie comfortably while a fine catheter is gently passed through your cervix to place the prepared sperm sample into the uterus. About two weeks later, a blood test can be arranged to check whether pregnancy has occurred.
There is no fixed number of IUI cycles that is right for everyone. The most appropriate approach will depend on factors such as age, diagnosis, sperm quality, ovulation pattern, and how treatment has progressed so far. While pregnancy can occur with the first cycle, it is common for IUI to require more than one attempt. In many cases, Dr Huang may discuss moving to IVF after around two unsuccessful IUI cycles, although this will always depend on your individual circumstances.
IUI is generally considered a low-risk and minimally invasive procedure. Some women may experience mild cramping or light spotting after insemination. If ovulation induction medication is used, you may experience temporary side effects such as bloating, breast tenderness, headaches, or mood changes. Complications are uncommon, but may include multiple pregnancy if more than one follicle develops, or, more rarely, infection.
Current IUI fees for Victoria are available on the Genea website https://www.genea.com.au/treatment-costs, including estimated out-of-pocket costs after Medicare rebates where applicable.
The chance of pregnancy with IUI varies according to factors such as age, egg quality, sperm quality, the reason for treatment, and whether ovulation induction is used. In general, success rates per cycle are lower than with IVF, which is why IUI is usually recommended only in selected situations where it is considered clinically appropriate. Because each IUI cycle offers a relatively modest chance of success, repeated unsuccessful cycles may have diminishing value, and IVF may become the more effective and efficient option. Dr Huang can discuss the likely chance of success in your individual circumstances and when it may be appropriate to move from IUI to IVF.
Most women find IUI quite manageable, although experiences do vary. The procedure is usually brief and may cause some temporary discomfort similar to period pain or the sensation of a cervical screening test. For most, any discomfort settles quickly afterwards.
Yes. IUI may be used with donor sperm in selected situations, including for single women and female same-sex couples. Whether IUI is the most appropriate option for you will depend on factors such as sperm quality, age, fertility history, and whether there are other reasons that IVF may offer a better chance of success.
