For many couples, the dream of starting a family is one of life’s biggest. But sometimes, getting pregnant doesn’t come as easily as one may think. If you’ve been trying for a while without success, your doctor might refer you to fertility treatments like IUI or IVF.
Both treatments can help you have a baby, but they work in different ways. Understanding the difference between IUI and IVF can help you decide which option may be right for you.
What is IUI?
IUI stands for Intrauterine Insemination, a simple, less expensive fertility treatment, which brings the sperm closer to the egg at the right time for fertilisation.
Here’s how it works:
- Your doctor will monitor your ovulation cycle to find when you’re most fertile.
- The sperm specimen, which is your partner’s or a donor’s, is washed and prepared in the laboratory.
- The sperm is then placed directly into your uterus by a thin, soft tube.
This process enhances the possibility of the sperm meeting the egg naturally. Everything else takes place inside your body as it would during a naturally conceived pregnancy.
IUI tends to be among the first treatments for doctors because it is simple, quick, and does not involve surgery.
What is IVF?
IVF stands for In Vitro Fertilisation; this is the more advanced treatment. “In vitro” means “in the lab.” In IVF, the sperm and egg meet outside of the body, and after fertilisation, the embryo is placed into the uterus.
The steps of the IVF process include:
- You’ll take fertility medicines to help your ovaries produce several eggs.
- Gently, the eggs are retrieved from your ovaries.
- The sperm is added to the eggs in a lab dish so fertilisation can happen.
- The best embryo is chosen and transferred into your uterus.
IVF gives doctors more control over the fertilisation process and is generally used when other treatments haven’t worked.
The Difference Between IUI and IVF
Understanding the difference between IUI and IVF will provide insight into which fertility route to take. Let’s break it down simply:
| Feature | IUI | IVF |
| Where fertilisation happens | Inside the body | Outside the body (in the lab) |
| Egg stimulation | Often uses mild medication or none | Uses stronger fertility drugs |
| Invasiveness | Non-surgical, simple procedure | Involves egg collection and embryo transfer |
| Success rate | Lower (around 10–20% per cycle) | Higher (40–60% per cycle, depending on age) |
| Cost | Less expensive | More costly |
| Time | Quick and simple | Takes several weeks per cycle |
| Best for | Mild fertility problems | Complex fertility issues or older age |
In other words, IUI is less invasive and purely a natural approach for couples with mild fertility issues, while IVF offers more control and higher success rates in more complex cases.
Who should attempt IUI?
IUI is usually recommended in the following cases:
- You have unexplained infertility (no known cause).
- Mild sperm problems – low count or slow movement
- You have cervical mucus abnormalities that impede sperm.
- You’re using donor sperm.
- You have ovulation problems, yet your fallopian tubes are open.
IUI is often the first step because of its affordability and ease. Most couples would start with a few cycles of IUI and then, if necessary, progress to IVF.
Who Should Try IVF?
IVF is considered a better option when:
- You have blocked or damaged fallopian tubes.
- You have severe male infertility (very low sperm count).
- You have endometriosis or polycystic ovary syndrome.
- You are over 35, and time is precious.
- You’ve tried IUI or other treatments without success.
IVF also allows advanced options like ICSI, in which a single sperm is injected directly into the egg, and genetic testing to ensure that the healthiest embryos are used.
Success Rates of IUI versus IVF
One of the biggest differences between IUI and IVF is their success rate.
- For IUI, the success rate per cycle is about 10–20%, depending on age and health.
- For IVF, the success rate is much higher — about 40–60% for women under 35, and a bit lower for women over 40.
IVF yields better results since doctors can select healthy eggs and embryos, improving your chances for pregnancy.

Costs: IUI vs. IVF
Another important difference between IUI and IVF is the cost.
IUI is less expensive since it omits the collection of the egg, fertilisation in the laboratory, and embryo culturing. More medicines and laboratory work, as well as more medical procedures, make IVF more expensive.
However, if you require multiple attempts at IUI, the costs add up. Sometimes, IVF may actually be more cost-effective in the long run if you need faster or more reliable results.
