What’s the Difference Between IUI vs. IVF? A Modern Guide for Fertility Patients
When trying to conceive with medical assistance, two of the most common fertility treatments are Intrauterine insemination (IUI) and In vitro fertilization (IVF). While both are effective in their own ways, understanding the main difference between IUI and IVF is crucial in choosing the right path for your fertility journey. In this guide, we’ll break down the procedures, success rates, risks, and ideal candidates for each, helping you decide what’s best for you.
At IVF Serum Clinic in Athens, one of the best IVF clinics in Europe, we offer personalized care whether you are considering IUI or IVF. Our team supports international patients through each stage of their treatment with compassion and expertise.
What Is the Difference Between IUI and IVF?
The main difference between IUI and IVF lies in how and where fertilization occurs. With IUI, washed sperm is placed directly into the uterus, allowing fertilization to occur naturally within the fallopian tubes. This makes IUI a less invasive and more natural fertility treatment, working best when the fallopian tubes are open and functional.
IVF, on the other hand, involves stimulating the ovaries, retrieving eggs, fertilizing them in a lab, and transferring the resulting embryo back to the uterus. Fertilization happens outside the body, offering more control, precision and valuable information about quality of embryos.
In simple terms: IUI is a step beyond natural conception, while IVF is a more advanced assisted reproductive technique.
Selection Criteria: Who Is IUI Suitable For?
Choosing between IUI and IVF depends heavily on the individual case. At IVF Serum, we evaluate each situation carefully to determine the best treatment approach.
IUI may be suitable for:
- Women with open and healthy fallopian tubes
- Mild male factor infertility
- Single women and those using donor sperm
According to international fertility guidelines, IUI is often recommended as a first-line treatment, especially when the tubes are open and sperm quality is within acceptable ranges. It is typically advised to try 3 IUI cycles before moving on to IVF, unless age, medical history, or other factors suggest otherwise.
IUI vs. IVF: Comparing the Procedures
- IUI Procedure: Timed with ovulation, washed sperm is inserted into the uterus using a thin catheter. It’s quick, minimally invasive, and closely resembles natural conception.
- IVF Procedure Step-by-Step: IVF includes ovarian stimulation, egg retrieval, lab-based fertilization, embryo culture, and embryo transfer. The cycle generally takes 6–8 weeks and is more complex.
IUI vs. IVF Success Rates Over 35 and Over 40
- IUI success rates decline after age 35 and significantly after 40. In such cases, IUI may still be attempted if other criteria are met, but chances are lower.
- IVF over 40 tends to be more effective, especially when embryo selection or donor eggs are involved.
At IVF Serum, the choice between IUI and IVF is always based on honest, personalized guidancefrom our fertility experts.
Which Is Better, IUI or IVF?
There’s no universal answer. IUI is simpler, more affordable, and less invasive, an ideal option for specific cases. IVF is better suited to more complex conditions and patients over 35 or with longer fertility histories.
Our team at IVF Serum helps you choose based on:
- Age and ovarian reserve
- Tubal status
- Sperm quality
- Duration of trying to conceive
- Previous treatments and results
IUI vs. IVF Price: What to Expect
- IUI is significantly more cost-effective per cycle.
- IVF involves higher upfront costs, but may be more efficient in certain cases where time and outcome are priorities.
If you’re evaluating IUI vs. IVF price, consider the long-term cost of multiple IUI attempts versus a single IVF cycle with higher success probability.
IUI vs. IVF: Risks and Side Effects
- IUI has minimal risks but lower success per cycle.
- IVF has higher success potential, but includes hormonal stimulation, egg retrieval, and a more demanding process.
Disadvantages of IUI may include:
- Lower success rates for women over 35
- Possible delays in pursuing more effective IVF
- Slightly increased risk of twins when using ovulation stimulation
Can I Get Twins with IUI? What About Gender Selection?
- Twins with IUI are possible if ovarian function is medically stimulated, though less common than in IVF.
- Gender selection is not allowed in Greece by our legislation frame, unless there is a medical reason.
- Genetic testing of the embryos which can be done through IVF but not though IUI.
Who Is Not a Good Candidate for IUI?
IUI is generally not recommended for:
- Women with blocked or damaged fallopian tubes
- Severe male infertility cases
- Women of advanced maternal age
- Couples with multiple failed IUI attempts
In these cases, IVF is a more reliable and effective path forward.
Can I Have a Healthy Baby with IUI?
Absolutely. IUI can lead to healthy pregnancies, particularly in younger women with no major reproductive issues. While miscarriage risk is primarily influenced by age and embryo health, IUI is a safe and low-risk option when used appropriately.
