IUI (Intrauterine Insemination)

Intrauterine Insemination (IUI) is a simple and minimally invasive fertility treatment that involves placing specially prepared sperm directly into the uterus around the time of ovulation. By increasing the number of sperm that reach the egg, IUI improves the chances of fertilization — especially in cases of unexplained infertility or mild male factor issues.

IUI is often the first treatment offered before more advanced procedures like IVF and is suitable for many couples trying to conceive.

What Does IUI Involve?

IUI is a relatively quick and painless procedure performed in a clinic setting:

  • Ovulation Monitoring: The woman’s cycle is tracked through blood tests and ultrasound to determine the best time for insemination. Ovulation may be triggered with medication if needed.
  • Sperm Collection & Preparation: A sperm sample is collected from the partner or donor. The sperm is "washed" to concentrate the healthiest sperm.
  • Insemination: Using a thin, flexible catheter, the prepared sperm is placed directly into the uterus — close to the time of ovulation.
  • Post-Procedure Monitoring: A pregnancy test is done around 2 weeks after the procedure.

These procedures are done safely and stored under strict conditions in fertility labs, giving patients more control over their reproductive future.

When is IUI Recommended?

  • Mild male infertility (low sperm count or motility)
  • Unexplained infertility
  • Cervical factor infertility
  • Ovulation disorders (e.g., PCOS)
  • Sexual dysfunction or painful intercourse

Frequently Asked Questions (FAQs) about IUI

No. Most women experience little to no discomfort during IUI. The procedure is quick and similar to a routine Pap smear.

Success depends on age, fertility diagnosis, and cycle type. On average:

  • 10–20% per cycle in women under 35

  • Higher chances when combined with ovulation-stimulating medications

Not always. IUI can be done in a natural cycle or with medications (e.g., Clomiphene, Letrozole, or gonadotropins) to improve ovulation and increase success rates.

The insemination procedure itself takes about 10–15 minutes. However, cycle monitoring typically begins early in the menstrual cycle and lasts for about 10–14 days.
