IUI is a fertility treatment where prepared sperm is placed directly into the uterus around the time of ovulation to improve the chances of conception.
IUI is not the right fit for every patient, and Dr Rozen’s starting point is always a thorough assessment of both partners before making any recommendation. For those where IUI is appropriate, it offers a straightforward, minimally invasive pathway that works with the body’s natural cycle.
IUI involves placing a prepared sperm sample directly into the uterus through a thin catheter, timed to coincide with ovulation. The procedure is quick and generally painless, similar to a pap smear, and does not require anaesthesia. It is also less invasive and more affordable than IVF.
From around day one to 14 of your cycle, blood tests and ultrasounds track follicle development and hormone levels to identify the optimal time for insemination. Ovulation induction medication may be prescribed to stimulate ovulation.
A semen sample is collected and processed in the laboratory to concentrate the healthiest sperm. Previously frozen sperm can also be used.
Once ovulation is confirmed, the prepared sperm is transferred directly into the uterus using a thin catheter. The procedure takes only a few minutes and does not require anaesthesia.
Hormone support may be provided to help maintain the uterine lining. Normal daily routines can continue, and a healthy lifestyle is encouraged throughout the waiting period.
Around two weeks after insemination, a blood test confirms whether conception has occurred.

IUI success rates in Australia are approximately 10-20% per cycle, and this may increase with ovulation induction medication. After six cycles, the cumulative success rate can rise to 60-70%.1 IUI tends to be more successful for women under 35 with mild infertility and a healthy ovarian reserve. Conditions such as blocked fallopian tubes, severe male infertility, and advanced maternal age are better suited to IVF.

“IUI is a genuinely valuable option for the right patient, and part of my job is making sure we’re recommending it for the right reasons. When it’s the right fit, it offers a gentler, more accessible path that I’m glad we have in our toolkit.”
