How Successful Is The First Try Of IUI?
Many hopeful parents ask this before committing to fertility treatment. Clinical data shows that first-cycle pregnancy rates depend on age, diagnosis, and medication use. Read on to learn exactly what influences those odds and how you can prepare for your procedure.
What to Know Before You Try IUI
Before you try IUI, first, realize that IUI remains less invasive and less costly than IVF, but success depends on several variables: egg quality, sperm health, timing, and underlying diagnoses. Review your insurance benefits; plans vary widely, and consult a fertility specialist. For budgeting tips, see our guide to affordable IUI in Kansas City. If you need spiritual encouragement along the way, you might find comfort in our Christian prayers for fertility as you prepare.
What is the IUI Process?
The IUI process is as follows: After ovarian stimulation (or a natural cycle), your doctor monitors follicles via ultrasound and bloodwork.
When an egg is ready, you provide a sperm sample—either from your partner or a donor. The clinic "washes" the sperm to concentrate healthy swimmers, then injects them directly into your uterus.
Some providers perform a second insemination 24 hours later, though that's not universally standard. You then wait about two weeks before taking a pregnancy test.
When considering "how successful is the first try of IUI," the fertility clinic you choose is very important. Although each clinic follows the same scientific procedure, each one performs customer service differently.

What is IUI Success?
IUI success is typically measured by fertility specialists as pregnancy rates (how many patients received positive pregnancy tests) and live birth rates per cycle. According to CNY Fertility, on average:
Natural cycles: ~10% per attempt
Oral meds (Clomid, Letrozole): 15–20%
Gonadotropin-stimulated: 20–25%
Success hinges on age, sperm count, fallopian tube health, and medication protocol.
Who Can Use the IUI Procedure?
IUI suits many scenarios:
Unexplained infertility (failed to get pregnant after 12 consecutive months of trying)
Low sperm count or motility
Mild endometriosis
Desire to avoid genetic conditions via donor sperm
Single women seeking pregnancy
Cervical mucus issues
Erectile or ejaculatory problems
Should You Try IUI?
You should try IUI if you fit any of the above categories and have at least one open fallopian tube. IUI offers a first-line option, which begs the question, "How successful is the first try of IUI?" This question is probably how you got here; however, if you manage a severe tubal condition or have had multiple failed cycles, your specialist may recommend advancing to IVF.

What is the Success rate of IUI's First Attempt?
Studies show the success rate of IUI's first attempt is roughly a 10–20% chance of conception on cycle one. Younger women (under 35) lean toward the upper end, while over 40 patients may see rates as low as 3–9%.
Can You Get Pregnant on the First Try of IUI?
Yes, you can get pregnant on the first try of IUI. Many couples achieve a pregnancy on cycle one, especially when combined with oral fertility medications.
How Many People Get Pregnant on the First Round of IUI?
Data shows about 1 in 7 to 1 in 10 couples conceive on their first round of IUI, with rates rising over subsequent cycles. So, when thinking about "how successful is the first try of IUI," know that the answer is about 10-20%.
Is It Normal for the First IUI to Fail?
Yes, it is normal for the first IUI to fail. Roughly 80–90% of first cycles don't result in pregnancy. Failure doesn't predict future outcomes: most successful IUIs occur within three to four attempts.
IUI has the lowest success in situations where:
You have moderate to severe endometriosis
Your partner's sperm count is very low
You face severe tubal disease or multiple pelvic infections
If IUI isn't suitable, your doctor may recommend IVF instead.

How to Improve IUI Success Rates
Here is how you can improve IUI success rates:
Optimize your health: Maintain a BMI between 18 and 25 and manage conditions like PCOS.
Choose the right meds: Discuss oral vs. injectable protocols with your specialist.
Timing is critical: Follow your doctor's ovulation trigger and insemination schedule precisely.
Work with a top clinic: Experience matters; outcomes often improve with higher-volume providers.
IVF vs. IUI Success Rates
The IVF success rate is generally 40–60% live births per cycle, while the IUI success rate is 10–25%. IVF is costlier and more invasive, but may suit couples after multiple failed IUI attempts.
Rate of Multiples With IUI Vs. IVF
The rate of multiples with IUI vs. IVF breaks down like this:
IUI: ~2–3% twins when using injectables
IVF: ~20–30% (depending on the number of embryos transferred)
Holding Space for Whatever Comes
The first round of IUI brings hope but also a lot of unknowns. If it doesn't lead to pregnancy, that doesn't mean you failed. It means your story is still unfolding.
Whether this is your first or fourth cycle, God sees your heart and your hurt. Be gentle with yourself, stay connected to your support system, and take your next step when you're ready, with clarity and compassion.
