IUI is a simple fertility treatment option that involves placing sperm directly into the uterus around the time of ovulation. IUI is often the initial step in fertility treatment, designed to help individuals or couples who have struggled to get pregnant naturally or have medical concerns that may reduce the chances of fertilisation.
IUI treatment is often recommended by a fertility specialist as a first-line, less invasive option before progressing to more complex treatments like IVF. In Australia, an IUI cycle may include ultrasound monitoring, blood tests, and hormone support to stimulate the ovary and improve timing, particularly in cases of irregular ovulation or male factor infertility such as low sperm count.
There are many situations where sperm may not be able to effectively travel through the female’s reproductive tract to meet the sperm and egg, but assisted insemination allows us to bypass these factors and place sperm directly into the uterus. This helps sperm get closer to the egg and creates a higher probability of fertilisation occurring, although the sperm still needs to reach and naturally fertilise the egg on its own.
IUI may be the right treatment if you have or are experiencing:
Artificial insemination is also commonly used in situations where a female partner needs to use a partner’s frozen sperm or a donor’s sperm. IUI treatment is often the first process recommended by specialists during fertility treatment, due to its less invasive procedure compared to other treatments. Part of IUI also includes a process known as sperm ‘washing’, which involves using laboratory techniques to identify the most active and best quality sperm within a sample and separate them to be used in the insemination process.
An IUI cycle can be timed through a natural cycle or supported with hormone medication to stimulate ovulation. Monitoring may include ultrasound scans and blood tests to track follicle development in the ovary and determine optimal timing.
In a woman’s natural cycle, ovulation typically occurs around 14 days after the start of a period, but commonly does vary. Women can opt to complete the IUI procedure without medication by tracking their natural cycle and having sperm introduced to the uterus at the time of ovulation. Alternatively, medication may be prescribed to be more certain of the time of ovulation in women who have infrequent or irregular periods.
Step-by-step IUI procedure:
As with any fertility treatment, it is not guaranteed that you will fall pregnant straight away. Many individuals and couples go through multiple cycles of IUI to give themselves the best chance of becoming pregnant and having a baby. We are there to support you and guide you through every step of the process.
IUI is a less invasive procedure with a small risk of complications. However, medications used to stimulate the ovary can increase the risk of multiple pregnancy and rarely ovarian hyperstimulation syndrome.
There is also a minor risk of infection or spotting after catheter insertion. While IUI treatment improves the chances, the success rate depends on several factors, including the underlying cause of infertility, egg quality, and sperm health.
Artificial insemination can be the first step in your assisted fertility journey, but other treatment cycles may be needed if you are unable to fall pregnant. Above everything, we always prioritise your health and your needs in guiding our treatment recommendations.
IVF is a more advanced fertility treatment where eggs are retrieved from the ovary and fertilised with sperm in a laboratory. The resulting embryo is transferred into the uterus to achieve pregnancy. Compared to IUI, IVF bypasses the fallopian tubes entirely.
ICSI is similar to IVF, but a single sperm is injected directly into an egg. This is particularly useful in cases of low sperm count or severe male infertility.
As women age, it becomes less likely that they will be able to fall pregnant naturally, but freezing your eggs as early as possible can help you prolong your ability to reproduce and try for a baby when you’re ready. Whether for personal or medical reasons, egg freezing is a way to help you try and get pregnant in the future.
Ovulation induction uses hormone medications to regulate and stimulate ovulation, improving timing and increasing the chances of success when combined with IUI.
The cost of IUI will vary for different individuals based on their circumstances and treatment needs. You can find out more about our estimated out-of-pocket IUI costs on our Fees page.
Many IUI costs are partially subsidised by Medicare, with patients able to receive a rebate if they have a referral letter for their treatment. The Extended Medicare Safety Net (EMSN) also provides an additional rebate on top of the regular amount when your costs go over an annual threshold. The EMSN threshold in 2024 is $2544.30. Our specialists can help you understand what you may be eligible for in terms of an IUI Medicare rebate.
The process of IUI is relatively painless, but some patients may experience discomfort, particularly when the catheter is being placed. This may be felt as a temporary pinching sensation or some cramping, but the speed of the procedure means that this discomfort is usually over quickly. Any pain after IUI can usually be treated with over the counter pain medication, but your doctor will advise of any particular aftercare instructions.
IUI is a less-invasive treatment option that involves helping sperm reach the egg around the time of ovulation by placing a sample directly into the uterus. IUI is usually one of the first fertility treatments attempted, prior to receiving IVF or other complex treatments. Fertilisation in an IVF cycle occurs outside of the body with an embryo being implanted, while in IUI, fertilisation occurs within the body, with sperm given assistance to reach the egg.
IUI can be a simple first step towards your pregnancy goals. If you are considering IUI, we’re here to help make the process as smooth and supportive as possible.
