TL;DR: Before starting IUI, your care team will usually recommend a few tests to make sure the treatment is a good fit. These may include hormone and ovarian reserve testing, a check of your fallopian tubes, semen analysis, and ovulation monitoring. Some patients may also need infectious disease screening, uterine testing, or genetic screening.
You’ve decided you’re ready to move forward. Maybe you’ve spent months tracking cycles, timing everything carefully, and hoping each test will finally show something different. By the time you meet with a fertility specialist, you may just want to start treatment and feel like something is finally happening.
So when your doctor recommends tests before IUI, it can feel frustrating. You may wonder why you can’t begin treatment right away.
Those tests are there to give your care team a clearer picture of what’s happening and whether IUI is the right next step for you. At King Square Fertility in Markham, we aim to use that information to plan your treatment more carefully and avoid putting you through a cycle that may not have a strong chance of working.
So, what does your fertility team need to know before your first IUI cycle? Here’s what to expect.
Intrauterine insemination (IUI) works by placing prepared sperm directly into the uterus around the time of ovulation. It sounds straightforward, and in many ways, it is. But for IUI to work, three things need to line up:
If any of these pieces are missing or unclear, IUI may not be the right fit, or the cycle may not succeed. Testing gives your fertility team the information they need to recommend treatment confidently, not cautiously.
Think of it this way: you wouldn't set out on a road trip without checking your route. Testing helps your team know where you're starting from.
One of the first steps is understanding how your ovaries are functioning. This usually involves blood tests to measure hormone levels, often done early in your menstrual cycle.
For IUI to have a good chance of working, sperm needs to be able to reach the egg. That usually means at least one fallopian tube needs to be open.
An HSG, or hysterosalpingogram, is an X-ray test that helps your care team check the shape of your uterus and see whether your fallopian tubes are open.
During the test, a small amount of dye is placed through the cervix and into the uterus. As the dye moves through the reproductive tract, X-ray images show whether it can pass through the fallopian tubes.
The test usually takes about 15 to 30 minutes. You may feel some cramping, similar to period cramps, during or shortly after the procedure. Your clinic may suggest taking an over-the-counter pain reliever beforehand.
If both tubes are blocked, IUI may not be the best option because the sperm and egg can’t meet. In that case, your care team may discuss treatments such as in vitro fertilization (IVF), which doesn’t rely on the fallopian tubes in the same way. If one tube is open, IUI may still be possible.
Not everyone needs an HSG before IUI, but your fertility specialist may recommend one to make sure there is a clear path for fertilization before treatment begins.
A semen analysis gives your care team a clearer picture of sperm health and whether IUI is likely to be a good fit.
The test looks at a few important things:
These results help your fertility specialist determine whether any male fertility factors could affect treatment.
A semen analysis is a standard part of fertility testing and is usually completed at a clinic or lab. Results are often available within a few days.
If the sperm count or motility is lower than expected, your care team may recommend additional male fertility services or talk with you about whether IUI still makes sense. In some cases, IVF with ICSI may offer a better chance of fertilization.
Even if your periods are regular, your care team may still want to confirm when ovulation is happening so they can time IUI as closely as possible.
There are a few ways they may do this:
Timing matters with IUI because the sperm needs to be placed in the uterus close to ovulation.
Your clinic will use these results to choose the best time for insemination, often within about 24 to 36 hours of an LH surge or trigger shot.
Not everyone needs the same testing before IUI. Your fertility specialist may recommend a few additional tests based on your health history, previous pregnancies, and initial results.
Before treatment involving sperm preparation, you and your partner may be asked to complete blood tests for infections such as HIV, hepatitis B and C, and syphilis. This is a routine safety step at fertility clinics.
If your doctor wants a closer look at the inside of your uterus, they may recommend a sonohysterogram or hysteroscopy. These tests can help identify concerns such as fibroids, polyps, or scar tissue that could affect treatment.
In some situations, genetic screening may also be recommended before treatment. Carrier screening can show whether you or your partner carries certain inherited genetic conditions and help your care team discuss any next steps with you.
Before you begin IUI, it helps to know that your treatment plan is based on the right information. Testing can show your care team how you’re ovulating, whether your fallopian tubes are open, how sperm health may affect treatment, and whether any other concerns need attention first.
At King Square Fertility in Markham, we offer fertility assessments, female fertility services, male fertility services, semen analysis, IUI, IVF, and personalized fertility planning in one supportive setting.
Our team will review your results, explain what they mean in plain language, and help you understand which treatment options may fit your diagnosis and goals.
If you’re considering IUI, start by speaking with your doctor about getting a referral. Once your referral is in place, reach out to our team to learn more about preparing for treatment and what testing you may need first.
Even if you’ve been trying for months or years, testing is still important. Tracking cycles and timing intercourse can tell you a lot, but they can’t show whether your fallopian tubes are open, whether ovulation is happening consistently, or whether sperm health may be affecting your chances. Testing helps fill in those gaps before treatment begins.
An HSG can cause some cramping or pressure, but the discomfort is usually brief. Many women compare it to period cramps. Your clinic may suggest taking an over-the-counter pain reliever beforehand, and if you’re feeling anxious, let your care team know so they can talk you through the procedure.
Sperm health can change over time, so your clinic may want a fairly recent result before IUI. In many cases, a semen analysis from the past three to six months may be acceptable. If it has been longer, or if earlier results were borderline, your care team may recommend repeating the test.
A low sperm count doesn’t automatically mean IUI is off the table. Your specialist will look at how many moving sperm are available after the sample is prepared and whether that number gives IUI a reasonable chance of working.
If the count is too low, your care team may discuss IVF with ICSI or other options that may be better suited to your situation.
