IVF vs IUI: What is the Difference and Which One Should You Choose?
When couples face infertility, two of the most common treatment options recommended by fertility specialists are IUI (Intrauterine Insemination) and IVF (In Vitro Fertilization).
A frequent question many couples ask is: “Should we start with IUI or go directly to IVF?” This article will guide you through the differences procedure, success rates, costs, and how to choose the right option for your situation.
What is IUI?
IUI (Intrauterine Insemination) is a simpler and less invasive fertility treatment compared to IVF.
Procedure:
1. The woman is monitored for ovulation (with or without medication).
2. A semen sample is collected and washed to select the healthiest sperm.
3. The sperm is directly placed into the uterus during ovulation.
Best suited for couples:
• The woman has at least one healthy fallopian tube.
• The man’s sperm count and motility are near normal.
• The couple has been trying for less than 3–5 years.
Advantages of IUI:
• Simple procedure, less invasive.
• Lower cost (approx. 10,000–20,000 THB / 300–600 USD per cycle).
• Quick recovery, minimal discomfort.
Limitations of IUI:
• Lower success rate (10–20% per cycle).
• Less effective for women over 35 years old.
• May require multiple attempts.
What is IVF?
IVF (In Vitro Fertilization) is a more advanced treatment where eggs are retrieved, fertilized with sperm in a laboratory, and then transferred back into the uterus.
Procedure:
1. Ovarian stimulation with fertility medication.
2. Egg retrieval and sperm collection.
3. Fertilization in the lab (IVF or ICSI if sperm quality is poor or oocyte thicker than usual).
4. Embryo culture and transfer to the uterus.
Best suited for couples:
• Women over 35 years old.
• Blocked or damaged fallopian tubes.
• Male infertility (low sperm count or motility issues).
• Couples with recurrent miscarriages or genetic concerns.
Advantages of IVF:
• Higher success rate (30–60% per cycle depending on age).
• Allows genetic testing (PGT-A/PGT-M, NGS).
• Option to freeze eggs or embryos for future use.
Limitations of IVF:
• Higher cost (approx. 200,000–300,000 THB / 6,000–10,000 USD per cycle).
• More complex, requiring multiple clinic visits.
• Potential side effects from fertility drugs.
Which One Should You Choose?
The choice between IUI and IVF depends on:
• Age of the woman
• Duration of infertility
• Medical conditions affecting fertility
• Budget and expectations
- Younger couples with mild infertility may benefit from trying IUI first.
- Couples with advanced age, blocked tubes, or complex infertility should consider IVF to maximize success rates.
Conclusion
Both IUI and IVF are effective fertility treatments but serve different patient needs. The right option depends on your medical profile, age, and personal goals.

Q: Does undergoing multiple cycle of IVF increase the chances of success?
A: Yes, undergoing several IVF cycles can improve the likelihood of achieving pregnancy.
