Key points

  • Timed intercourse targets the fertile window - the 5 days before and day of ovulation

  • IUI places washed, concentrated sperm directly into the uterus at ovulation

  • IUI adds meaningful benefit for donor sperm, ejaculatory problems and some cervical or mild male factors

  • For unexplained subfertility, UK guidance favours moving to IVF over routine IUI in many cases

  • A fertility specialist can quantify which route suits your specific findings

Understanding it

About Timed intercourse vs IUI.

Timed intercourse costs nothing and suits couples early in their journey with open tubes and reasonable sperm. IUI is a step up in intervention: sperm are prepared in the laboratory and delivered past the cervix, sometimes in a cycle stimulated with mild medication.

Confirmation of tubal patency and semen parameters first, then an honest comparison of per-cycle success rates for your diagnosis and age - escalating to IVF when the numbers favour it. On the NHS, routine referrals of this kind often take 20-45+ weeks in many areas, whereas a private fertility specialist can typically see you within around two weeks, with any tests and treatment arranged promptly afterwards.
