IUI when the wife has PCOS and the husband's sperm count is borderline
When the wife has PCOS and the husband's sperm count is only mildly low, IUI is often a sensible step. Tablets, with low-dose injections if needed, help one or two eggs grow; scans time the release; and on the day, the husband's sample is washed and concentrated so the most active sperm are placed inside the womb.

This is one of the commonest situations in a fertility clinic. The wife has PCOS, so she does not release an egg every month, and the husband's semen report sits in the middle range: not normal, but not very low either. In this video, in Hindi, Dr Mayur Pai talks through exactly this situation while the husband's sample is being prepared in the laboratory, and shows the prepared sample and the IUI catheter.
Why this combination is common, and why IUI fits it
Each problem on its own is often mild. PCOS means ovulation is irregular, so there are fewer chances each year for an egg to meet sperm. A borderline count means fewer active sperm reach the egg when it is released. Together, they lower the chance in any month more than either would alone.
IUI answers both halves. Ovulation induction makes sure a mature egg is released at a known time, and the IUI places a concentrated sample of the husband's most active sperm inside the womb at that moment, giving them a much shorter journey.
First, confirm the diagnosis
Before starting, the doctor makes sure IUI is the right tool:
- For the wife: a vaginal ultrasound, which often shows the typical polycystic ovary, and basic hormone and blood tests.
- The tubes: at least one tube must be open, because in IUI the egg and sperm still meet inside the tube. This is checked with a dye test such as an HSG, if it has not already been done.
- For the husband: a semen analysis, repeated if the first result is borderline, because counts vary from one test to the next.

Step 1: helping an egg grow
In PCOS the ovary holds many small follicles, but often none of them grows on to release an egg by itself. Treatment usually starts with an ovulation tablet in the first days of the cycle, which prompts the body to make more of its own FSH, the hormone that grows follicles.
If the ovaries do not respond to tablets, or respond slowly, a low-dose FSH injection is added and increased in small steps. The aim in IUI is modest: one or two mature follicles, not many. PCOS ovaries can suddenly over-respond, so if too many follicles grow, the doctor may cancel that cycle to avoid a multiple pregnancy or over-stimulation. How eggs develop in polycystic ovaries.
Step 2: tracking and timing the release
Usually from the second week of the cycle, vaginal scans every two or three days follow the growing follicles and the lining of the womb. When the largest follicle is mature, a trigger injection is given to complete the egg's ripening and release it at a predictable time. The IUI is then planned for about a day to a day and a half later, so the sperm are waiting when the egg arrives.
Step 3: preparing a borderline sample
On IUI day, the husband gives a fresh semen sample. A borderline sample often carries debris, dead or slow sperm and other cells along with the healthy sperm, and in the video Dr Pai shows how much of this is removed. The sample is layered over a special density-gradient fluid and spun gently, so the healthy, active sperm travel down and collect at the bottom while the debris stays above. The sperm are then washed again and concentrated into a small volume.
This takes about an hour. What matters for IUI is not the raw count on the report, but how many good, moving sperm are left after washing. Sperm preparation for IUI, step by step.
Step 4: the IUI itself
The prepared sperm are drawn into a thin, soft, flexible catheter, which is passed gently through the neck of the womb, and the sperm are released in the centre of the womb. It takes a few minutes and almost no one needs anaesthesia; if you are very anxious or sensitive, tell us beforehand and we will discuss options for your comfort. The catheter is single-use. You rest for fifteen to thirty minutes and go home, and no special precautions are needed afterwards.
Why a borderline count can still suit IUI
A borderline or "medium" count means there are fewer good sperm than ideal, but not so few that fertilisation inside the tube is out of reach. Washing and concentrating the sample, and placing it past the cervix at the right hour, makes the most of the sperm there are.
The husband can help too: stopping smoking, cutting down alcohol, avoiding heat around the testes and reaching a healthy weight all support sperm health. Sperm take about three months to develop, so changes show on a later report.
When the count or movement is very low, or the washed sample yields very few active sperm, IUI is unlikely to help and IVF with ICSI is the more sensible route. The doctor decides from your own reports, not from a fixed number. Low sperm count: IUI or IVF?
Do not lose time
The point Dr Pai returns to in the video is time. Couples often spend years on repeated "small" treatments, while age advances and the sperm count can fall. A sensible plan tries IUI for a limited number of well-monitored cycles. If pregnancy does not follow, the doctor looks further, for example with a hysteroscopy or laparoscopy, or advises moving to IVF. Starting earlier keeps more options open.

Your questions
What does a borderline sperm count mean?
It means one or more values in the semen report, such as the count or the share of moving sperm, are a little below the normal range, but not severely. Because results vary from test to test, a borderline report is usually repeated. For IUI, what matters most is how many active sperm remain after washing.
Which medicines help an egg grow in PCOS before IUI?
Usually an ovulation tablet, taken for a few days early in the cycle. If the ovaries respond slowly, a low-dose FSH injection is added in small steps. When the largest follicle is mature, a trigger injection times the release of the egg.
When is the IUI done after the trigger injection?
Usually about a day to a day and a half later, so that the prepared sperm are already in place when the egg is released. Your doctor sets the exact time from your scan, and the husband's sample is timed to match.
What happens if too many follicles grow?
The doctor may cancel the IUI that month and advise you to avoid intercourse until the next period, to prevent a multiple pregnancy or over-stimulation. The next cycle then starts with a gentler plan. Occasionally, the cycle can be converted to IVF instead.
IUI or IVF: which comes first with PCOS and a borderline count?
Most couples in this situation can reasonably start with IUI if the wife's tubes are open, she is younger and enough active sperm remain after washing. IVF comes first, or sooner, when age is against you, the sperm are very few or weak, or several well-run IUI cycles have not worked.
