IUI Treatment in Chennai — Gentle, Effective Care at Yaal Fertility Centre
Intrauterine Insemination — a gentle, less invasive fertility option
What is IUI Treatment?
Intrauterine Insemination (IUI) is a fertility treatment in which prepared sperm is placed directly into the uterus through a thin catheter, timed precisely to coincide with ovulation. Unlike IVF, fertilisation still happens naturally, inside the body — IUI simply gives sperm a substantial head start.
Normally, sperm must travel from the vagina, through the cervix, and up into the uterus and fallopian tubes, and only a tiny fraction of them survive the journey. IUI bypasses that. A semen sample is processed in our andrology laboratory to concentrate the healthiest, most motile sperm and remove seminal fluid and debris. That concentrated sample is then deposited directly into the uterus, placing far more viable sperm close to the egg than would ever arrive naturally.
Because fertilisation still depends on sperm meeting egg in the fallopian tube, IUI requires at least one open fallopian tube and reasonable sperm quality to work. It cannot help when the tubes are blocked, and it is not effective for severe male factor infertility — those situations need IVF or ICSI.
The procedure itself takes 5–10 minutes, needs no anaesthesia, and most women describe it as comparable to a Pap smear. You can return to normal activity immediately. It is considerably less invasive and less expensive than IVF, which is why it is often the sensible first treatment to try for the right candidates. Success rates are correspondingly lower: roughly 15–22% per cycle for women under 35, and we would rather you know that at the outset than be disappointed by it later.

Who Is It For?
Treatment Process
Fertility Assessment
Complete evaluation including hormone tests, ultrasound, tubal patency test, and semen analysis to confirm IUI suitability.
Ovulation Induction (if needed)
Mild medications may be used to stimulate egg development and ensure optimal timing. Regular ultrasound monitoring tracks follicle growth.
Trigger Injection
An injection is given to trigger ovulation at the precise right time, ensuring eggs are released when insemination is performed.
Sperm Preparation
The semen sample is processed in our andrology lab to concentrate the healthiest, most motile sperm for insemination.
Insemination Procedure
Using a thin, flexible catheter, the prepared sperm is placed directly into the uterus. The procedure takes 5-10 minutes and is painless.
Pregnancy Test
A blood pregnancy test is performed approximately 14 days after the procedure. Our team provides support and guidance throughout the wait.
Success Rates
| Age Group | Success Rate |
|---|---|
| Under 30 | 22% |
| 30–34 | 18% |
| 35–37 | 14% |
| 38–40 | 10% |
| Over 40 | 5% |
Success rates are based on clinical pregnancy per embryo transfer at Yaal Fertility Centre. Individual results may vary.
Should You Try IUI First, or Go Straight to IVF?
This is the question most couples are really asking when they research IUI, and it deserves a straight answer rather than a sales pitch. IUI is cheaper, gentler, and less medicalised than IVF. It is also substantially less likely to work in any given cycle. Whether that trade is worth making depends entirely on why you have not conceived.
IUI is a reasonable first step when: your fallopian tubes are open, sperm quality is normal or only mildly reduced, you are under 35, the infertility is unexplained or related to ovulation or cervical factors, and you have not been trying for a very long time. In this situation, starting with IUI risks relatively little and may spare you a far more demanding treatment.
Going directly to IVF is usually the better decision when: the fallopian tubes are blocked or damaged (IUI simply cannot work), male factor infertility is significant, you are in your late thirties or older and time itself is a factor, ovarian reserve is low, or moderate-to-severe endometriosis is present. In these cases IUI is likely to fail, and cycles spent on it are months lost at an age where months matter.
There is a real cost to trying IUI when it was never likely to succeed — not just money, but time and hope. There is an equally real cost to pushing someone into IVF who could have conceived more simply. Dr. Rukkayal will give you her honest assessment after your investigations rather than defaulting to either.
How Many IUI Cycles Are Worth Trying?
The general guidance is three to four well-timed cycles. If IUI has not worked by then, continuing it is usually a poor use of time and money, and IVF offers substantially better odds.
The reasoning is straightforward. IUI success is roughly constant per cycle — it does not improve with repetition. Most pregnancies that IUI is going to produce occur within the first three or four attempts. Beyond that point, the cumulative chance of success climbs only slowly, while the months accumulate and, if you are over 35, egg quality continues to decline in the background.
That said, the number is not a rule. It shifts with your circumstances: a 41-year-old with diminished ovarian reserve may be advised to move on after one or two cycles, or skip IUI altogether, because time is the scarcest resource. A 29-year-old with unexplained infertility and no other adverse findings might reasonably try four.
What matters is deciding the plan in advance — how many cycles, and what happens if they do not work — rather than drifting from one cycle into the next without a review point. Dr. Rukkayal will set that plan with you at the start.
What Affects IUI Success Rates?
IUI success is modest by nature, and honest about it: roughly 22% per cycle under 30, falling to about 5% over 40. The factors that move that number are:
- Age — the dominant factor, as with all fertility treatment, because it governs egg quality.
- Sperm quality after preparation — the count of motile sperm recovered after washing is one of the strongest predictors. Mild male factor may respond to IUI; significant male factor generally will not.
- Tubal patency — at least one open, healthy fallopian tube is essential. This is why a tubal test forms part of the assessment before IUI is offered.
- Cause of infertility — IUI performs best in unexplained infertility, cervical factor, and ovulation disorders. It performs poorly in tubal disease and severe male factor.
- Timing — insemination must coincide closely with ovulation, which is why monitoring and a trigger injection are used to pin down the window rather than estimating it.
- Ovulation induction — combining IUI with mild stimulation typically improves results over an unmedicated cycle by ensuring a mature follicle develops and timing is precise.
- Duration of infertility — the longer the period of trying without success, the lower the per-cycle chance.
Careful patient selection is what separates a worthwhile IUI programme from a disappointing one. Offering IUI to someone whose diagnosis predicts failure inflates cycle numbers and wastes the patient’s time.
What to Expect on the Day of Your IUI
IUI is an outpatient procedure and one of the least demanding treatments in fertility care. Knowing the sequence tends to remove most of the anxiety around it.
Before you arrive, you will have been monitored with ultrasound to track your follicle, and given a trigger injection to time ovulation precisely. Insemination is scheduled for the window when the egg is released.
The semen sample is produced on the morning of the procedure, or thawed if frozen or donor sperm is being used. It then goes to our andrology laboratory for preparation — a process that concentrates the most motile sperm and removes seminal fluid, which would cause cramping if introduced into the uterus directly. Preparation takes roughly an hour.
The insemination itself takes 5–10 minutes. You lie as you would for a routine gynaecological examination. A speculum is inserted, a soft, thin catheter is passed through the cervix, and the prepared sperm is released into the uterus. No anaesthesia is used, and most women feel little or nothing — some experience brief cramping as the catheter passes the cervix. You will typically rest for a short while afterwards.
Afterwards, you can return to normal activity straight away. Bed rest is not required and does not improve outcomes. Light cramping or spotting for a day is normal. Then comes the two-week wait, ending in a blood pregnancy test (beta-hCG) around 14 days later. Home urine tests taken earlier are frequently misleading — the trigger injection itself can produce a false positive — which is why we ask you to wait for the blood test.
IUI With Donor Sperm
IUI is the standard route for conception using donor sperm, and is used by single women choosing to become mothers, by same-sex female couples, and by couples where the male partner has no viable sperm.
The clinical process is identical to standard IUI, with one difference: the sample is donor sperm, which arrives frozen, quarantined, and screened, and is thawed and prepared on the day of insemination. Because donor samples are selected for good motility and count, sperm quality is generally not the limiting factor — which is why donor IUI often performs well when the woman’s own fertility is otherwise normal.
Donor conception in India is governed by the ART (Regulation) Act, 2021, which sets the rules for donor screening, consent, anonymity, and eligibility. These are legal requirements, not clinic preferences, and we will take you through what they mean for you before treatment begins.
