IUI (Intrauterine Insemination) places prepared, healthy sperm directly into the uterus around ovulation, giving sperm a head start. It’s often the first, least invasive fertility treatment, suited to couples with mild male-factor infertility, unexplained infertility, ovulation issues (like PCOD) or certain cervical problems. Success improves with the right timing, healthy habits and expert monitoring.
What is IUI?
IUI is a gentle fertility treatment in which a semen sample is washed and concentrated in the laboratory to select the healthiest, most active sperm, which are then placed directly into the uterus at the time of ovulation. By bypassing the cervix and shortening the journey to the egg, it improves the odds of sperm meeting egg. It’s far simpler than IVF — there’s no egg collection — which is why it’s usually the first step tried for suitable couples.
Who should consider IUI?
IUI is a good starting point for several situations: couples with mild low sperm count or motility, unexplained infertility, or irregular ovulation (for example with PCOD, where IUI is often combined with ovulation-stimulating medication). It also helps with cervical-factor issues and when using donor sperm. It’s less suitable where there’s significant tubal blockage or severe male-factor infertility, in which case IVF or ICSI is usually the better route — which is why a proper diagnosis comes first.
How the IUI process works
A typical cycle begins with tracking ovulation, sometimes using medication and follicle-tracking scans to grow and time a mature egg. A trigger injection may be given to time ovulation precisely, and on the chosen day a prepared sperm sample is passed into the uterus through a thin, soft catheter — a quick, usually painless step that takes just a few minutes. Progesterone support often follows to help the uterine lining. See medications used in IUI, preparing for an IUI cycle, and what happens after IUI.
Success rates — and how to improve them
IUI success varies with age, the underlying cause of infertility, and whether ovulation-stimulating medication is used, and it commonly takes more than one cycle to succeed. You can improve your chances by attending monitoring appointments so timing is precise, taking medications exactly as prescribed, keeping a healthy weight, eating well, staying lightly active, and avoiding smoking and alcohol. Because age is one of the biggest factors, earlier evaluation genuinely helps.
IUI vs IVF: which is right for you?
IUI is simpler, gentler and lower in cost, and is usually tried first for milder problems. IVF (and ICSI) is more involved — with ovarian stimulation, egg collection and laboratory fertilisation — but offers higher success per cycle and is the right choice for blocked tubes, significant male-factor infertility, or when IUI hasn’t worked after a few cycles. There’s no one-size-fits-all answer: your doctor recommends the path that fits your diagnosis, age and goals.
Common myths about IUI
A few myths cause unnecessary worry. IUI is not the same as IVF and doesn’t involve egg collection or the same level of stimulation. It is not painful for most women — at most there may be mild cramping afterwards. A single unsuccessful cycle does not mean it won’t work, as many pregnancies come in later cycles. And IUI does not “use up” your fertility.

IUI is simpler and usually tried first for milder problems; IVF has higher per-cycle success and suits more complex cases. Your doctor advises based on your diagnosis.
