IUI vs IVF: At a Glance
IUI places washed sperm directly into the uterus around ovulation — the egg and sperm still meet inside the body. IVF retrieves eggs from the ovaries, fertilises them in a lab, and transfers the resulting embryo back into the uterus. The shorthand: IUI assists conception; IVF performs it. IUI typically costs ₹15,000–₹30,000 per cycle in India. IVF typically costs ₹1.2L–₹2.5L per cycle. IUI takes about 4 weeks per cycle; IVF takes 6–8 weeks. IUI per-cycle success rate is 10–20% depending on age and cause; IVF is 40–55% in patients under 35 and falls steeply after 38.
When IUI Is the Right First Step
IUI is recommended when the underlying barrier to conception is mild and addressable: mild male-factor infertility (slightly low sperm count or motility but not severe), unexplained infertility in women under 35 with at least one open fallopian tube and adequate ovarian reserve, mild endometriosis, ovulation issues being treated with medication, donor sperm cycles for single mothers or same-sex couples, and cervical-factor infertility. Most clinics try 3 IUI cycles before escalating to IVF — beyond 3, the cumulative success curve flattens and the cost-effectiveness of IUI drops below IVF.
When IVF Is the Better Starting Point
Skip IUI and go straight to IVF when: the woman is over 38 (time-to-pregnancy matters and IVF success drops with age), AMH is low or there is diminished ovarian reserve, both fallopian tubes are blocked or damaged (IUI cannot work without functional tubes), severe male-factor infertility (low count + low motility, or azoospermia requiring TESA/PESA), moderate-to-severe endometriosis, recurrent pregnancy loss, or genetic concerns requiring PGT-A embryo screening. IUI in these scenarios is unlikely to succeed and delays effective treatment — sometimes by years.
Cost Comparison: IUI vs IVF in India
IUI per cycle in India: ₹15,000–₹30,000 base, plus ovulation medication ₹3,000–₹15,000 if used. Three IUI cycles = ₹50,000–₹1.2L total. IVF per cycle in India: ₹1.2L–₹2.5L base, plus stimulation drugs ₹40,000–₹1.2L (a major variable based on AMH and protocol), ICSI add-on ₹30,000–₹50,000, blastocyst culture ₹15,000–₹30,000, embryo freezing ₹25,000–₹40,000, PGT-A ₹20,000–₹30,000 per embryo tested. At Iswarya, an IVF starter package begins at ₹99,000 with the rest billed transparently as you go, and EMI is available from ₹9,999/month.
Success Rate by Age — The Honest Numbers
Per-cycle live-birth rates (combined Indian and international data): IUI under 35 — 10–20% per cycle; IUI 35–37 — 8–15%; IUI 38–40 — 5–10%; IUI over 40 — under 5%. IVF under 35 — 40–55%; IVF 35–37 — 35–45%; IVF 38–40 — 25–35%; IVF 41–42 — 15–20%; IVF over 42 with own eggs — under 10% (donor-egg IVF restores success to 50%+). These are not quotes — they are population averages. Iswarya publishes its centre-level success data at /success-rates and your specialist will share an age- and diagnosis-specific estimate during consultation.
Side Effects and Physical Demands
IUI side effects are mild: oral or low-dose injectable medication (cramping, bloating, mood shifts), the IUI procedure itself takes 5–10 minutes and feels similar to a Pap smear, mild risk of multiples (5–10%) if injectables are used. IVF side effects are more substantial: 10–14 days of self-administered hormone injections, bloating and discomfort during stimulation, egg retrieval under sedation (15–20 minutes, mild cramping for 1–2 days after), risk of ovarian hyperstimulation (1–2% serious cases), embryo transfer is painless but the two-week wait is emotionally taxing.
Timeline: How Long Each Path Takes
IUI: from consultation to pregnancy test, one cycle is roughly 4 weeks. Most patients try 3 cycles before escalating, so the IUI pathway often takes 3–4 months total. IVF: from consultation to pregnancy test, one cycle is 6–8 weeks (longer if blastocyst culture or freeze-all + FET protocol is used). A single IVF cycle takes about twice as long as IUI but converts to pregnancy 3–4× more often per cycle in patients under 35.
How to Decide — The Questions to Ask Your Doctor
Bring these to your consultation: (1) Based on my AMH, age, and tubal status, what is my predicted IUI success rate per cycle? (2) If I do 3 IUIs and they fail, what does the data say about my IVF success rate after that? (3) Is there a clinical reason to skip IUI and go straight to IVF in my case? (4) What is the all-in cost — including drugs and add-ons — for the recommended path? (5) If I freeze embryos in my first IVF cycle, what does cycle 2 cost vs cycle 1? Honest, numerical answers to these are a strong signal of clinic transparency.
The Iswarya Approach
At Iswarya we run a 39-year-old, ICMR-compliant fertility programme across 80+ centres. Our standard pathway: a 30–45 minute initial consultation, AMH + semen analysis + tubal evaluation in week 1, an honest age-and-diagnosis-specific recommendation between IUI and IVF, transparent EMI from ₹9,999/month, and ICMR-audited success rates published per centre. If your local doctor has recommended one path and you would like a second opinion before starting, we offer free second opinions at /second-opinion.
