IUI is generally not painful. It is similar to a smear test — some women feel mild cramps or pressure lasting a few minutes. No anaesthesia is needed. The procedure takes 5–10 minutes in the clinic. You can go home immediately and resume normal activities the same day.

IVF vs IUI — Which is Better? Difference, Success Rate & Cost

Q: What is the difference between IVF and IUI?

IUI (Intrauterine Insemination) places washed, concentrated sperm directly inside the uterus near the fallopian tubes during natural or stimulated ovulation. Fertilisation still happens naturally inside the body. IVF (In Vitro Fertilisation) retrieves eggs from the ovaries, fertilises them with sperm outside the body in a laboratory, grows embryos for 3–5 days, and then transfers the best embryo directly into the uterus. IVF bypasses the fallopian tubes entirely and offers much higher success rates per cycle but is more complex and costly than IUI.

Q: Who should do IUI and who should do IVF?

IUI is suitable for: unexplained infertility (under 35, trying less than 3 years), mild male factor (count 5–15 million/ml, motility 30–40%), cervical factor infertility, donor sperm cycles, and mild ovulation disorders. IVF is recommended for: blocked or damaged fallopian tubes, severe male factor (count below 5 million, very low motility), failed 3 IUI cycles, age over 38, low ovarian reserve (AMH below 1 ng/ml), PCOS not responding to tablets, endometriosis, recurrent miscarriage requiring PGT-A, or any situation where time is critical.

Q: Should I skip IUI and go directly to IVF?

Skipping IUI and going directly to IVF is recommended in specific situations: blocked fallopian tubes, severe male factor infertility, age over 38 or low AMH, failed 3 IUI cycles, endometriosis (moderate-severe), recurrent miscarriage needing genetic embryo testing (PGT-A), or PCOS not responding to oral medications. For younger women with mild infertility and open tubes, IUI is a reasonable first step — it is less invasive and lower cost. However, if you are over 37 or your AMH is low, time is precious and moving to IVF faster is usually the better choice.

What Is IUI and What Is IVF? — Clear Explanation

💙 IUI — Intrauterine Insemination

The simpler of the two. Sperm is collected, washed and concentrated in the lab, then placed directly inside the uterus using a thin catheter — right at the time of ovulation. Fertilisation still happens naturally, inside your body, inside the fallopian tube.

No egg retrieval — eggs stay in the body
Procedure takes 5–10 minutes, no anaesthesia
Can be done in a natural cycle or with mild stimulation
Go home same day, resume activities immediately
Fallopian tubes must be open for IUI to work
Lower cost per cycle than IVF

💗 IVF — In Vitro Fertilisation

The more powerful treatment. Ovaries are stimulated to produce multiple eggs, which are retrieved under sedation. Eggs are fertilised with sperm in the IVF lab, embryos are grown for 3–5 days, and the best embryo is transferred directly into the uterus. Fallopian tubes are bypassed completely.

Full control over egg fertilisation and embryo development
Egg retrieval under sedation — comfortable procedure
Transfer of best-quality embryo directly into uterus
Extra embryos can be frozen for future cycles
Works even with blocked tubes or severe male factor
Allows genetic testing (PGT-A) of embryos before transfer

Key difference: In IUI, fertilisation happens inside your body. In IVF, fertilisation happens outside your body in a lab, and an embryo is transferred into your uterus. IVF gives the doctor much more control — and much higher success rates.

IVF vs IUI — Full Comparison Table

Feature	IUI (Intrauterine Insemination)	IVF (In Vitro Fertilisation)
Where fertilisation happens	Inside the body (fallopian tube)	Outside the body (IVF laboratory)
Eggs retrieved?	No — eggs remain in the body	Yes — eggs retrieved under sedation
Injections needed	Mild — 1 injection or oral tablets	Daily injections for 10–12 days
Procedure time	5–10 minutes, no sedation	Egg retrieval 20–30 min (sedation); Transfer 15–20 min
Fallopian tubes required?	Yes — at least one must be open	No — tubes bypassed completely
Success rate per cycle (under 35)	10–20% per cycle	40–60% per cycle
Genetic embryo testing (PGT-A)	Not possible	Yes — chromosomes tested before transfer
Embryos frozen for future use	Not applicable	Yes — extra embryos can be frozen
Best for	Mild male factor, unexplained infertility (under 35), cervical factor, donor sperm	Blocked tubes, severe male factor, age 38+, low AMH, failed IUI, PCOS, recurrent miscarriage
Number of attempts recommended	Up to 3 cycles	2–3 cycles before assessing further

Who Should Choose IUI and Who Should Choose IVF?

💙 Start with IUI if:

You are under 35 with unexplained infertility
Mild male factor: sperm count 5–15 million/ml
Motility 30–40% (below normal but not severely low)
Cervical factor — poor mucus quality
Irregular ovulation that responds to tablets
Using donor sperm (single women, same-sex couples)
Fallopian tubes confirmed open on HSG
Time on your side — trying less than 2 years, under 35

💗 Go directly to IVF if:

One or both fallopian tubes are blocked or damaged
Severe male factor: count below 5 million, very low motility
3 failed IUI cycles — no point in more IUI
Age 38 or above — time is critical, IVF is faster
AMH below 1.0 ng/ml — low ovarian reserve
PCOS not responding to oral medications
Endometriosis (moderate to severe)
Recurrent miscarriage needing PGT-A embryo testing
Previous IVF embryos available (frozen) — do FET

"My doctor says try IUI first. But I am 38. Should I wait for 3 IUI cycles?"
This is one of the most common dilemmas at our clinic. At 38, each month matters. A typical IUI cycle takes 4–6 weeks. Three failed IUI cycles = 4–6 months lost. For women 38 or older, we generally recommend moving directly to IVF to maximise your chances while egg quality is still optimal. Time is a resource you cannot recover — IVF is not "too early" when your age is the factor.

The "Skip to IVF" Decision at Mother Hospitals

We individualise every recommendation. When we suggest going directly to IVF, it is always backed by specific reasons — not to increase costs or skip steps unnecessarily. IVF is recommended immediately when:

Diagnosis makes IUI unlikely to work (tubes, severe male factor)
Age-related time pressure — every month of egg quality counts
Patient preference — understanding all options and choosing the most effective
Previous failed IUI cycles show IUI is not the right path
Need for PGT-A genetic testing — only possible with IVF

Frequently Asked Questions — IVF vs IUI

What is the difference between IVF and IUI?

IUI (Intrauterine Insemination) places washed sperm directly inside the uterus at ovulation — fertilisation still happens naturally inside the fallopian tube. IVF (In Vitro Fertilisation) retrieves eggs from the ovaries, fertilises them with sperm in a laboratory, grows embryos for 3–5 days, and transfers the best embryo directly into the uterus. IVF bypasses fallopian tubes entirely. IVF is 2–4 times more successful per cycle but is more complex and costly. The right choice depends on your diagnosis and age.

Who should do IUI and who should do IVF?

IUI works for: mild male factor infertility, unexplained infertility (under 35), cervical factor, donor sperm, and irregular ovulation with open fallopian tubes. IVF is needed for: blocked tubes, severe male factor (very low sperm count/motility), age 38 or older, low AMH, failed 3 IUI cycles, PCOS not responding to tablets, moderate-severe endometriosis, or recurrent miscarriage needing PGT-A genetic testing.

What is the success rate of IUI vs IVF in Hyderabad?

IUI success rate per cycle is 10–20% for women under 35 with mild infertility. After 3 cycles, cumulative success reaches 30–40%. IVF success rate per cycle (live birth) is 40–60% for women under 35 with good ovarian reserve. After 2 IVF cycles, cumulative success is 70–80%. IVF is significantly more effective per attempt. However, IUI may still be the right starting point for the right patient — the key is correct diagnosis first.

Is IUI painful?

IUI is generally not painful. It is similar in feel to a cervical smear — you may feel mild pressure or cramps for a few minutes. No anaesthesia is required. The procedure takes 5–10 minutes and you can go home immediately and resume normal activities the same day. Mild spotting or cramping afterward is normal and expected.

Should I skip IUI and go directly to IVF?

Skipping IUI and going directly to IVF is recommended when: fallopian tubes are blocked or damaged, male factor is severe, you are 38 or older (time is critical), AMH is low, you have endometriosis (moderate-severe), or you need PGT-A genetic testing of embryos. For younger women under 35 with mild infertility and open tubes, IUI is a reasonable less invasive first step. At Mother Hospitals, we assess each couple's specific situation before recommending the most effective path — not the most expensive one.
