How is IUI different from IVF?

IUI places washed sperm directly into the uterus (cost ~$500–$2,000/cycle) and suits mild infertility. IVF fertilizes eggs outside the body at higher cost but with higher success rates — recommended for blocked tubes, severe male factor, or repeated IUI failures.

Who is a good candidate for IUI?

IUI is suitable for ovulatory dysfunction (with ovulation induction), mild-to-moderate male factor, cervical factor infertility, unexplained infertility, or patients using donor sperm (single women, lesbian couples).

What are IUI success rates?

Each IUI cycle has roughly a 10–20% success rate; cumulative rates over 3–6 cycles reach 40–50%. Success depends on age, diagnosis, and sperm quality. Women under 35 using ovulation-stimulating medication see the best outcomes.

IUI causes only mild discomfort similar to menstrual cramps. The procedure takes 5–10 minutes, requires no anesthesia, and patients can resume normal activities immediately afterward.

How many IUI cycles before switching to IVF?

Most physicians recommend moving to IVF after 3–6 failed IUI cycles, sooner for women over 35. If significant tubal factors or severe male infertility are identified, your doctor may recommend skipping IUI and proceeding directly to IVF.

Typical trials before considering IVF

What is IUI?

IUI places washed and concentrated sperm directly into the uterus during ovulation, reducing the distance sperm must travel. The procedure is quick and relatively painless, similar to a Pap smear.

Who is a Candidate for IUI?

Unexplained infertility
Mild male factor infertility
Cervical mucus issues
Ovulation disorders
Single women or same-sex couples (donor sperm)

The IUI Procedure

Ovulation Monitoring

Ultrasound and blood tests track your ovulation timing; ovulation induction medications may be used

Sperm Preparation

A sperm sample is washed and concentrated, removing low-motility sperm and debris

Insemination

A soft catheter places the sperm into the uterus — takes 5-10 minutes; brief rest before discharge

IUI Cost

IUI is among the most affordable assisted reproduction options. Per-cycle costs are significantly lower than IVF:

Cost Item	Estimated Cost (USD)
Ultrasound monitoring & ovulation tracking	$300–$600
IUI insemination procedure	$500–$1,000
Ovulation induction medications (if used)	$200–$1,000
Total per cycle	$1,000–$2,600

* Costs vary by clinic and treatment plan. Some insurance policies cover IUI. Even across multiple cycles, total IUI costs typically stay below a single IVF cycle.

Frequently Asked Questions

What is the success rate of IUI?

IUI success rates per cycle are approximately 10-20%, depending on several factors: age (higher rates under 35), cause of infertility (ovulation disorders respond well to IUI with medications), sperm parameters (higher motility = better results), and whether ovulation induction is used. Compared to IVF, IUI has lower success rates per cycle but is significantly less expensive, making it a sensible first-line option.

What is the difference between IUI and natural intercourse?

IUI offers several advantages: (1) Washed and concentrated sperm contains more motile sperm per insemination; (2) Sperm is delivered directly to the uterus, bypassing the cervix — especially useful for cervical mucus issues; (3) Combined with ultrasound monitoring and precise ovulation timing, insemination is more accurately targeted. For mild fertility issues, IUI is more efficient than natural attempts alone.

How many IUI cycles before considering IVF?

Most physicians recommend evaluating a switch to IVF after 3-4 unsuccessful IUI cycles. However, IVF may be recommended sooner for: tubal issues (IUI requires at least one open fallopian tube), severe male infertility, patients over 35 (time is a factor), or known IVF indications. Your physician will provide personalized guidance based on your situation.

Is the IUI procedure painful? What should I do afterward?

IUI is typically nearly painless; some patients feel mild cervical discomfort similar to light menstrual cramps. Rest for 10-15 minutes afterward, then resume normal activities — no special restrictions are needed. Avoid vigorous exercise and intercourse for two weeks (after confirmed ovulation). A blood hCG test two weeks after the procedure confirms whether you are pregnant.
