IVF vs IUI – Which Is Better?
When couples face difficulty conceiving, one of the most common questions is: Should we choose IUI or IVF? Both treatments are effective fertility solutions, but they differ in process, complexity, cost, and success rates.
At Iswarya Fertility Centre, fertility specialists carefully evaluate each couple’s condition before recommending the most suitable treatment. Understanding the difference between IVF and IUI can help you make an informed decision.
What Is IUI?
Intrauterine Insemination (IUI) is a relatively simple fertility procedure where specially prepared sperm is directly placed into the uterus during ovulation.
How IUI Works:
Ovulation is monitored (natural or stimulated cycle).
A semen sample is collected and processed in the lab.
Healthy, motile sperm are inserted into the uterus using a thin catheter.
When Is IUI Recommended?
Mild male factor infertility
Unexplained infertility
Ovulation disorders
Cervical mucus issues
Couples trying for a shorter duration
IUI is less invasive and more affordable compared to IVF, but success rates per cycle are generally lower.
What Is IVF?
In Vitro Fertilisation (IVF) is an advanced assisted reproductive technique where fertilisation occurs outside the body in a laboratory.
How IVF Works:
Ovarian stimulation with fertility medications
Egg retrieval procedure
Fertilisation in the embryology lab
Embryo culture and monitoring
Transfer of healthy embryo(s) into the uterus
IVF allows closer monitoring of fertilisation and embryo development, offering higher success rates in certain cases.
IVF vs IUI – Quick Comparison
| Factor | IUI | IVF |
| Procedure Complexity | Simple, minimally invasive | More advanced and procedural |
| Cost | Lower per cycle | Higher per cycle |
| Success Rate | Moderate | Higher, especially in complex cases |
| Lab Involvement | Basic sperm processing | Advanced embryology support |
| Recommended For | Mild infertility | Moderate to severe infertility |
| Time to Results | May require multiple cycles | Often fewer cycles needed |
This table highlights why treatment choice depends on individual medical factors.
Success Rates – What to Expect?
IUI Success Rate: Typically ranges between 10–20% per cycle, depending on age and fertility factors.
IVF Success Rate: Can range between 40–60% per cycle, depending on age, embryo quality, and medical condition.
At Iswarya Fertility Centre, modern embryology labs and strict quality protocols help optimise IVF outcomes.
When Is IUI the Better Option?
IUI may be suitable when:
Female partner has good ovarian reserve
Fallopian tubes are open
Male factor infertility is mild
The couple prefers a less invasive approach initially
It is often considered a first-line treatment before moving to IVF.
When Is IVF the Better Option?
IVF is generally recommended for:
Blocked fallopian tubes
Severe male infertility
Failed IUI cycles
Advanced maternal age
Endometriosis
Genetic screening requirements
In such cases, IVF offers better control and improved success rates.
How Iswarya Fertility Centre Guides You
At Iswarya Fertility Centre, treatment decisions are personalised based on:
Age and ovarian reserve
Semen analysis results
Medical history
Duration of infertility
Previous treatment outcomes
The centre provides:
Comprehensive diagnostic evaluation
Advanced embryology lab support
Personalised stimulation protocols
Transparent counselling about success rates and costs
The goal is not just choosing IVF or IUI — but selecting the right treatment at the right time.
Emotional & Financial Considerations
Couples often consider:
Emotional stress of multiple cycles
Financial planning
Time commitment
Physical comfort
While IUI is less expensive, repeated cycles may increase overall cost and delay effective treatment. IVF, though costlier initially, may offer quicker results in certain cases.
Key Takeaway – Which Is Better?
There is no universal “better” option. The best treatment depends on individual fertility factors.
IUI is ideal for mild infertility and early intervention.
IVF is more suitable for moderate to severe cases or after failed IUI attempts.
With expert evaluation and advanced technology at Iswarya Fertility Centre, couples receive personalised guidance to maximise their chances of parenthood.
