Does IUI treat male factor infertility?

During IUI, a laboratory prepares a semen sample and places the motile sperm inside the uterus near ovulation. This bypasses the vagina and cervix and reduces the distance sperm travel. It may be considered when sperm movement or concentration is mildly reduced, ejaculation is difficult, or donor sperm is being used. IUI cannot repair absent sperm production, severe sperm abnormalities, or a blockage that prevents sperm from being collected without specialist treatment.

The female partner’s ovulation, fallopian tubes, ovarian reserve, and uterine health also influence whether IUI is sensible. Male and female assessments are considered together rather than treating the semen result in isolation.

A clinician will usually review one or more semen analyses, including sperm concentration, movement, and shape, while asking about medicines, illness, heat exposure, operations, and reproductive history. Testing may include hormones or an examination when the history suggests a hormonal or anatomical cause. The couple’s plan may involve timed ovulation, medication, or another assisted reproduction option. Ask how the sample will be collected, whether sperm preparation changes the plan, and what result would lead to a different approach.

Arrange an evaluation when conception has not occurred after regular attempts, or earlier after testicular surgery, chemotherapy, recurrent ejaculation problems, or a known sperm concern. Seek prompt care for sudden severe testicular pain, swelling with fever, blood in semen that persists, or an inability to pass urine. These issues need direct assessment and are not answered by choosing IUI alone.

Ask what the semen results show, whether the finding is likely to change, and whether repeat testing is needed. Discuss options for improving sperm health, the role of ovulation timing, how the female partner’s tests affect the plan, and when IVF or sperm retrieval should be considered.
