What's the difference between IVF and IUI?
IVF and IUI are both fertility treatments, but they work in very different ways. In simple terms, IUI tries to help sperm meet the egg inside the body, while IVF joins egg and sperm outside the body and then places an embryo into the uterus.
How IUI works
IUI stands for intrauterine insemination. Around ovulation, washed sperm is placed directly into the uterus with a thin catheter, so it has a shorter path to travel.
IUI is usually simpler, faster, and less expensive than IVF. Some people do IUI with cycle tracking alone, while others use fertility medicines to help the ovaries release eggs.
You can learn more about the process on our IUI treatment page or in our broader fertility treatment guide.
How IVF works
IVF stands for in vitro fertilization. The ovaries are stimulated to produce multiple eggs, the eggs are collected, and eggs and sperm are combined in a lab. If fertilization happens, one embryo may later be transferred to the uterus.
IVF has more steps, more appointments, and usually a higher cost than IUI. It can also be used in situations where IUI may be less likely to help, but the best option depends on your age, fertility history, diagnosis, and goals.

The biggest differences: cost, time, and success
The clearest differences are complexity, cost, and typical success per cycle. IUI is often tried first because it is less invasive and generally costs much less. IVF is more involved, but it may offer higher success per cycle for some people.
Typical US costs vary a lot by clinic and medication needs, but IUI is often in the hundreds to low thousands of dollars per cycle, while IVF is often in the many thousands to tens of thousands per cycle. Insurance coverage also varies.
Success rates are not one-size-fits-all. They can differ widely based on age, sperm factors, ovulation issues, tubal factors, embryo quality, and clinic practices. A licensed fertility doctor can explain what may be realistic in your situation, and our guide to understanding success rates can help you ask better questions.

- IVF is usually more involved and more expensive
- Success can vary widely from person to person
Who each treatment may suit
In general, IUI may be considered for certain mild fertility issues, ovulation timing support, some sperm issues, or when using donor sperm. IVF may be considered when there are blocked tubes, more significant male factor infertility, a need for genetic testing, lower egg supply, or when prior treatments have not worked.
That said, there is no universal rule that everyone should start with IUI, or that IVF is always the better choice. The right path depends on your medical history and priorities, including budget, time, comfort level, and how aggressive you want treatment to be.

Questions worth asking before you decide
If you are comparing IVF and IUI, it can help to ask clear, practical questions before your first visit. This is especially important if you are new to the US healthcare system or trying to understand insurance and out-of-pocket costs.
Helpful questions include:
- Based on my age and history, why are you recommending IUI or IVF?
- What testing should happen first?
- What are the typical total costs, including medicines and monitoring?
- How many cycles do people in situations like mine sometimes try before changing plans?
- What are the main risks, time commitments, and chances of cancellation?
Our guides can help you prepare, but only a licensed fertility doctor can advise you on your own care.
IUI is usually simpler and cheaper, IVF is more complex and usually costs more, and the right choice depends on your specific situation.
Common questions
Is IVF better than IUI?
Not always. IVF is more involved and often more expensive, but it may offer higher success per cycle for some people. The best choice depends on age, diagnosis, goals, and budget.
Why do some people try IUI first?
IUI is usually simpler, less invasive, and less expensive than IVF, so some people start there. But it is not the right first step for everyone.
Does IVF work faster than IUI?
It depends what you mean by faster. An IUI cycle is usually simpler and shorter, but IVF may sometimes lead to a clearer next step or higher success per cycle for certain patients.
Is IUI cheaper than IVF?
Usually yes. In general, IUI costs much less per cycle than IVF, though exact costs vary by clinic, medicines, testing, and insurance coverage.
Can CoralConceive tell me which one I should do?
No. CoralConceive is a free matching service, not a clinic or doctor. We can help you find fertility clinics near you, but treatment decisions should be made with a licensed fertility doctor.
