IUI vs IVF: Choosing the Right Treatment - Complete guide

Patient: Dr. Malpani, my gynecologist suggested that I start with IUI before considering IVF. He said both are part of ART, so they should work the same way. Is that true?

Dr. Malpani: Not at all! IUI (Intrauterine Insemination) and IVF (In Vitro Fertilisation) are completely different treatments, even though they both fall under ART (Assisted Reproductive Technology). They are designed for different kinds of infertility and have very different success rates.

Patient: I see. Then when is IUI actually a good option?

Dr. Malpani: IUI works best for couples where the sperm count is normal, fallopian tubes are open, and the woman is ovulating. It is commonly recommended for:

• Women with PCOS who don’t ovulate regularly.
• Couples with unexplained infertility (where all tests are normal, but they still aren’t conceiving).

However, IUI has major limitations.

Patient: What do you mean by limitations?

Dr. Malpani: The biggest advantage of IUI is that it is cheaper and simpler than IVF. It can be done by a regular gynaecologist without specialised equipment. But the trade-off is its very low success rate—only 10-15% per cycle.

Patient: That doesn’t sound very encouraging! My doctor said that “washing” the sperm before IUI makes it more effective. Is that true?

Dr. Malpani: That’s a common myth. Gynaecologists often tell patients that “sperm washing” selects the best quality sperm and improves IUI success rates.

But here’s the truth:

• If the sperm is abnormal and cannot fertilise an egg, washing it won’t make a difference.
• For male factor infertility (low count, poor motility, abnormal morphology), IUI is a terrible treatment.
• If the sperm cannot fertilise the egg naturally, IVF with ICSI (Intracytoplasmic Sperm Injection) is the best option.

Patient: That makes sense. But shouldn’t I at least try IUI before moving to IVF?

Dr. Malpani: That depends on your case.

• If you have PCOS or unexplained infertility and normal sperm parameters, you can try IUI.
• But if your tubes are blocked, your egg reserve is low, or sperm quality is poor, IUI will not work. IVF is the only logical choice.

Patient: My gynaecologist suggested I try IUI six times before thinking about IVF. Does that sound right?

Dr. Malpani: Absolutely not! That’s a complete waste of time and money. Studies show that if IUI is going to work, it usually works within three cycles.

If you don’t conceive after three IUI attempts, continuing to do more IUI cycles is pointless. It just delays IVF and wastes precious time.

Patient: But what if I switch to another gynaecologist? Maybe someone else can do a “better” IUI?

Dr. Malpani: That’s another mistake many couples make. If IUI has already failed three times, the problem is not the doctor, but the treatment itself!

• Changing doctors will not change your biology.
• Your body does not care how many different gynaecologists perform IUI.
• If IUI has failed multiple times, it is time to move on to IVF.

Patient: I’ve heard that IVF is expensive and invasive, which is why IUI is recommended first. Is that true?

Dr. Malpani: IVF is definitely more advanced and costs more than IUI, but it’s also far more effective. The success rate of IVF is 40-50% per cycle, compared to just 10-15% for IUI.

Many patients actually end up spending more money on repeated IUI cycles, only to realize later that they should have done IVF in the first place.

• IVF gives you a much better chance of getting pregnant sooner.
• IVF allows us to select the best embryos, which increases success rates.
• IVF helps bypass problems like blocked tubes, poor sperm quality, and failed IUI cycles.

Patient: So, would you recommend skipping IUI and going straight for IVF?

Dr. Malpani: For some patients, yes! If you:

• Have male factor infertility (low sperm count, motility, or morphology issues)
• Have blocked fallopian tubes.
• Are above 35 and have a low ovarian reserve (low AMH, high FSH)
• Have already done three failed IUIs.

Then IVF is the right choice, and IUI is a waste of time.

Patient: Thank you, Dr. Malpani. I now understand that I need to make an informed decision, rather than just following whatever my gynecologist suggests.

Dr. Malpani: Absolutely! Too many patients blindly follow their doctors without understanding the difference between IUI and IVF. Be informed, make a plan, and don’t waste time on ineffective treatments!
