Sometimes the simplest approach is the right first step. IUI gives nature a measured advantage without the complexity of IVF.
IUI is the least invasive fertility treatment that still involves clinical intervention. By placing concentrated, washed sperm directly into the uterus at the moment of ovulation, it increases the odds without the cost or complexity of IVF. For many couples, it is worth trying before escalating to more intensive treatment.

Intrauterine insemination places a prepared sperm sample directly into the uterus through a thin catheter, timed to coincide with ovulation. The goal is straightforward — get more healthy sperm closer to the egg at the right moment. IUI can be done with your natural cycle or with mild ovarian stimulation to improve timing and follicle development.
The sperm sample is washed and concentrated in the laboratory beforehand, removing seminal fluid and selecting the most motile sperm. IUI suits mild male factor infertility, unexplained infertility, cervical factor issues, and is commonly used with donor sperm for single women and same-sex female couples.
IUI is a simple procedure, but the monitoring and timing that surround it still matter. Thai clinics offer the same specialist oversight as European centres at a fraction of the price.

Prices are approximate and vary by technique, surgeon, and hospital. Your personalised quote will include a full cost breakdown.
A single IUI cycle in Thailand costs between $800 and $1,450. Natural cycle IUI without medication sits at the lower end. Stimulated cycles with monitoring and medication cost more. Multiple cycles can often be packaged at a reduced per-cycle rate — ask your coordinator about this.
The cost covers specialist consultations, cycle monitoring (ultrasound and blood tests), sperm preparation and washing, the insemination procedure itself, and a follow-up appointment. If ovarian stimulation medication is used, this is typically an additional charge. Donor sperm costs are separate if applicable.
The main variable is whether you use a natural or stimulated cycle — medication adds cost. Donor sperm, if needed, is an additional line item. Some patients combine IUI with basic diagnostic tests during the same trip, which is cost-effective. The number of monitoring visits may vary slightly depending on how predictable your cycle is.
Pricing varies by the complexity and scope of the procedure. Typical ranges at our partner hospitals in Thailand:
Exact pricing is confirmed after your consultation and treatment plan are finalised.
IUI in Thailand costs 50–60% less than equivalent treatment in the US ($2,000–$3,600), Australia (A$1,750–A$3,200), and UK (£1,600–£2,800). Because IUI often requires multiple cycles, the savings compound — three cycles in Thailand may cost less than a single cycle at home.
The decision between natural and stimulated IUI depends on your cycle regularity and diagnosis. Your specialist will recommend whichever gives you the best per-cycle odds without unnecessary medication.
No stimulation medication is used. Your natural cycle is monitored with ultrasound and blood tests to identify the developing follicle and predict ovulation. A trigger injection may be given to time ovulation precisely. The insemination is performed 24–36 hours after the trigger or at natural ovulation.
Low-dose fertility medication — oral tablets like letrozole or clomiphene, or low-dose injectable gonadotropins — stimulates one or two mature follicles. Monitoring ensures the response stays controlled. This modestly improves per-cycle success rates by ensuring at least one good follicle develops and ovulation timing is precise.
IUI is a straightforward procedure, but the sperm preparation and timing protocols that support it are where the clinical skill shows up.
The raw semen sample is processed in the laboratory to remove seminal fluid, debris, and non-motile sperm. What remains is a concentrated preparation of the most actively swimming sperm, suspended in a small volume of culture medium. This concentrated sample is what gets deposited into the uterus — maximising the number of healthy sperm reaching the fallopian tubes.
Precise timing is the single most important variable in IUI success. The insemination window is narrow — roughly 12–24 hours around ovulation. Ultrasound monitoring tracks follicle development, and a trigger injection (hCG) induces ovulation on a predictable schedule. Insemination is performed 24–36 hours after the trigger, placing sperm in the uterus when the egg is available.
If you are having a stimulated cycle, low-dose medication begins in the first few days of your period. For a natural cycle, monitoring starts around day eight to ten. Ultrasound scans and blood tests every two to three days track follicle growth and hormone levels. The process is non-invasive and appointments are quick.
Once a mature follicle is identified, a trigger injection induces ovulation. Your partner provides a sperm sample on the insemination day, or a frozen or donor sample is thawed. The lab washes and concentrates the sperm — a process that takes one to two hours.
The insemination itself takes just a few minutes and feels similar to a smear test. A thin catheter is passed through the cervix and the prepared sperm is deposited into the uterus. No anaesthesia is needed. You can return to normal activities immediately afterwards.
A pregnancy blood test is performed 14 days after insemination. You can take this test in Thailand or at a laboratory near your home. Your coordinator stays in touch throughout the waiting period. If the result is negative, a cycle review determines whether to adjust the protocol or try again.
You can fly the same day as the insemination if needed, though most patients stay for one to two days afterwards. There are no physical restrictions. Many patients choose to fly home before the pregnancy test and take it at a local laboratory. Your Thai clinic will review the result remotely and advise on next steps.
Immediately. IUI requires no recovery time. You can walk, eat, work, and carry on with daily life right after the procedure. There is no evidence that resting improves outcomes. Avoid only extreme physical exertion and very hot baths during the two-week wait.
Most specialists recommend three to four well-timed IUI cycles before moving to IVF, provided there are no factors that make IVF a better first choice. Cumulative success over three to four cycles can reach 30–40% for women under 35. If IUI has not succeeded after this point, the probability of further IUI cycles working drops significantly, and IVF is usually the logical next step.
IUI is one of the lowest-risk fertility treatments available. Serious complications are rare, and most cycles are completed without any issues when properly monitored.
Stimulated cycles are monitored closely. If too many follicles develop, the cycle may be cancelled or converted to IVF to avoid a high-order multiple pregnancy. Thai clinics follow international guidelines to keep IUI as safe and controlled as possible.
Yes. IUI is a simple outpatient procedure with minimal risk. Thai fertility clinics perform it under specialist oversight with the same monitoring standards used in UK and European clinics. The main safety consideration — managing ovarian stimulation to avoid multiple pregnancy — is handled through careful monitoring and strict follicle-count thresholds.
The primary risk to manage is multiple pregnancy from ovarian stimulation. If monitoring shows more than two mature follicles, the cycle should be cancelled or converted. This is standard practice at reputable clinics. Using low-dose stimulation protocols rather than aggressive medication further reduces the risk. Choose a clinic that takes this seriously rather than one that transfers multiple embryos to inflate success statistics.
IUI is not the right treatment for blocked fallopian tubes, severe male factor infertility, or advanced maternal age where time is a significant factor. If you have failed three to four IUI cycles, the evidence strongly supports moving to IVF rather than continuing with a lower-probability treatment. Your specialist will make this recommendation clearly when the data supports it.
IUI is a straightforward procedure, but the monitoring and timing that surround it require genuine expertise. Here is what to look for.
Our partner clinics offer IUI as part of a comprehensive fertility service — meaning if IUI does not succeed, you can progress directly to IVF at the same centre with the same team. This continuity matters. The clinics use high-resolution ultrasound for cycle monitoring and have on-site andrology labs for same-day sperm processing.
IUI monitoring and timing decisions are made by board-certified reproductive endocrinologists at our partner clinics. These are not general gynaecologists adding fertility services as an afterthought — they are specialists whose primary clinical focus is helping patients conceive. The quality of monitoring directly affects IUI success rates.
Ask whether IUI is performed by a fertility specialist or a generalist. Confirm the clinic uses ultrasound monitoring for follicle tracking rather than relying solely on ovulation predictor kits. Check whether the andrology lab can process and wash sperm on-site. And make sure the clinic has clear protocols for cycle cancellation if too many follicles develop.
IUI is a lower-intensity treatment with correspondingly modest per-cycle success rates. Here is what realistic expectations look like.
Per-cycle success rates for IUI are 10–20% for women under 35 with no severe fertility factors. Stimulated cycles tend to perform slightly better than natural cycles. Cumulative success over three to four cycles reaches 30–40%. After four unsuccessful cycles, success rates per additional attempt drop significantly, and IVF becomes the more efficient path forward.
Age is the biggest factor — egg quality declines with time, and IUI does not bypass this. Sperm quality after washing matters — the post-wash total motile sperm count should ideally be above five to ten million for reasonable IUI success. Tubal patency is essential — at least one open tube is required. Ovulatory function and timing precision also play significant roles.
An IUI cycle typically requires 7–14 days in Thailand. Here is how to plan your visit.
A natural cycle IUI requires five to seven days if you arrive around day eight to ten of your cycle. A stimulated cycle requires seven to fourteen days, starting from day two to three of your period. The insemination is typically performed around day twelve to sixteen. You can fly home the same day or the next.
Your coordinator handles scheduling and communication with the clinic. The treatment quote covers specialist consultations, cycle monitoring with ultrasound and blood tests, sperm preparation and washing, the insemination procedure, and a follow-up appointment. Medication and donor sperm are quoted separately if applicable. A full breakdown is provided before you commit.
Many patients combine their IUI cycle with other fertility investigations — hormone testing, a full fertility assessment, or diagnostic procedures like hysteroscopy — during the same trip. This is an efficient use of your time in Thailand and provides your specialist with a complete picture of your fertility status alongside the treatment itself.
