IUI when both partners have a factor: PCOS and a low sperm count
When the wife has PCOS and the husband has a low sperm count, both problems are treated in the same cycle. Medicines help her ovary release a good egg at a known time, while his sample is washed and concentrated in the laboratory, so the healthiest sperm are placed in the womb just as the egg is released.

This video is in Hindi and runs just over half an hour. Dr Mayur Pai explains how IUI is planned for a couple where the wife has PCOS and the husband has a low sperm count, and shows how an IUI sperm sample is prepared, step by step. This page covers the same ground in English.
Why does it matter that both partners have a factor?
Fertility belongs to the couple, not to one person. When the wife has PCOS and the husband has a low sperm count, each problem on its own might be mild, but together they add up: fewer months in which an egg is released, and fewer good sperm to meet it when it is. Treating one side while ignoring the other simply loses time.
That is why both partners are assessed from the start. For her, that means an ultrasound, hormone tests and a check that the tubes are open; for him, a semen analysis, repeated if it is low. The plan then treats both sides in the same cycle.
Her side: helping a PCOS ovary release one good egg
In PCOS the ovary holds many small follicles but often fails to ripen and release one of them, so periods are irregular and ovulation is hard to predict. You can see what this looks like in PCOS causes and the ultrasound picture. For IUI, gentle ovulation medicines, usually tablets and sometimes small hormone injections, help one or two follicles grow. Because a PCOS ovary can over-respond, the medicines are kept gentle and the follicles are followed closely on scans. When a leading follicle is ready, a trigger injection times its release.
Where weight is a factor, even a modest weight loss often helps the ovary respond more predictably. How ovulation is brought on and timed in PCOS is covered in more depth in IUI with PCOS and a borderline sperm count.
His side: making the most of a low count
For the husband, the months before IUI matter. Any infection shown by pus cells in the semen is treated, smoking and heavy alcohol are stopped, and heat to the testes is avoided, because sperm take about two to three months to form. Before the IUI itself, he is asked to leave a gap of two to five days since the last ejaculation, so the sample is neither low in number from too short a gap nor sluggish from too long a one. Whether a low count still suits IUI is discussed in IUI for a low sperm count.
How is the sperm sample prepared, step by step?
On IUI day, the sample goes through a careful sequence in the laboratory. This is the part the video shows in detail.
- Collection. The husband gives a fresh sample by masturbation into a sterile container, without any lubricant. The container is labelled and checked against the couple's names.
- Liquefaction. Semen is thick when first produced. It is kept warm for a short while until it turns liquid, so the sperm can be separated.
- A first look. A drop is checked under the microscope to see how many sperm there are and how well they move.
- Washing. Using a swim-up or density-gradient method and a gentle spin, the moving sperm are separated from the seminal fluid, dead sperm, other cells and debris.
- Concentrating. The active sperm are gathered into a small drop of clean culture fluid.
- A final check. The prepared sample is examined again. The number of moving sperm now present tells us more than the original report did.
- Loading. The sample is drawn into a thin, soft tube, the names are confirmed once more, and the IUI is done.
The whole process usually takes about an hour. The two washing methods are explained in sperm preparation for IUI.
How do the two halves come together on the day?
Timing is where the two halves of the plan meet. The trigger injection fixes when her egg will be released, and the IUI is planned for a day or so later. On that day his sample is given, prepared and placed in the womb while the egg is on its way. The procedure itself takes a few minutes, needs no anaesthesia, and she can go home after a short rest.
What if IUI does not work?
IUI is planned for a limited number of well-timed cycles, followed by a review. If pregnancy has not happened, or if the husband's count turns out lower than it first seemed, IVF with ICSI is usually the next step. In ICSI a single sperm is placed directly into each egg, so the low count matters far less. PCOS still needs care in IVF, because the ovaries can over-respond to stimulation, so the medicines and scans are tailored closely to her.
Where treatment happens
This guide is by Dr Mayur Pai, MBBS, MS (Obstetrics & Gynaecology), a fertility and laparoscopy specialist. Pai Hospital in Goa has its own operating theatre and its own IVF laboratory, so her scans, his sample preparation and the IUI happen in one place, under one team. Free patient transport is available: the hospital's car collects you from anywhere in Goa and takes you home again.

Your questions
Can IUI work if the wife has PCOS and the husband has a low sperm count?
It can, when the count is only mildly or moderately low, enough active sperm are recovered after washing, and her tubes are open. The medicines help her release an egg at a known time, and the prepared sperm are placed close to it. If the count is very low, IVF with ICSI is usually advised.
What should the husband do before IUI day?
Leave a gap of two to five days since the last ejaculation, avoid alcohol and smoking, and keep away from heat such as very hot baths. If his report showed pus cells, the infection should be treated before the cycle. On the day, he gives a fresh sample, which the laboratory prepares.
How long does sperm preparation take on IUI day?
Usually about an hour from the time the sample is given. The semen first turns liquid, then it is washed, concentrated and checked under the microscope before the IUI.
Why is the sperm sample washed instead of being used as it is?
Raw semen contains seminal fluid, dead sperm and other cells. The fluid can cause cramps if it is placed in the womb, and sperm that do not move cannot reach the egg. Washing keeps only the active sperm, in a small, clean volume.
Does PCOS make IUI riskier?
The main risk is that a PCOS ovary can grow too many follicles in response to the medicines. That is why the medicines are kept gentle and the follicles are watched on scans. If too many grow, the cycle can be stopped to keep her safe and avoid a multiple pregnancy.
