IUI or IVF: which comes first, and why

Couples often arrive asking for IVF straight away, or the opposite — wanting to avoid it at any cost. Neither is the right starting point. The right treatment depends on what the tests show, and for many couples that is something simpler than IVF.

What IUI is

In intrauterine insemination, washed and concentrated sperm are placed directly into the uterus around the time of ovulation, through a thin tube. It takes a few minutes, needs no anaesthetic, and is often combined with tablets or injections to help ovulation. Fertilisation still happens inside the body.

What IVF is

In IVF, the ovaries are stimulated to produce several eggs, which are collected in a short procedure and fertilised in the laboratory. One embryo is then placed in the uterus. ICSI is a laboratory step within IVF, used mainly when sperm are a problem.

When IUI is a reasonable first step

IUI may suit couples where at least one tube is open, the sperm count is near normal, and the woman is younger — for example with mild male factor, ovulation problems, unexplained infertility, or difficulty with intercourse.

When going to IVF sooner makes sense

When both tubes are blocked, the sperm count is very low, egg reserve is reduced, the woman is older, or several IUI cycles have not worked. In these situations, more IUI cycles can cost time that matters.

How the decision is made

After an evaluation of both partners, your doctor should explain why one treatment is recommended over the other, how many attempts are reasonable before moving on, and what each will cost. You should never feel rushed into the more complex option, or held back from it when it is the right one.
