IUI (Intrauterine Insemination): The Complete Patient Guide

Intrauterine Insemination (IUI) is a widely used form of assisted fertilization. It involves placing freshly prepared, highly motile sperm directly into the uterine cavity at the precise time of ovulation. By bypassing the cervical barrier and increasing the density of sperm near the fallopian tubes, IUI helps nature take its course more effectively.

Who Benefits from IUI?

IUI is an excellent first-line treatment for couples with:

• Unexplained sub-fertility.
• Mild endometriosis or cervical factor infertility.
• Mild male factor infertility (low motility).
• Need for donor sperm (due to azoospermia or genetic conditions).

The Rationale: Why Semen Preparation Matters

Semen washing is not just a cleaning process; it is a critical step for success. At Talwar Fertility, our lab preparation achieves the following:

The Procedure: What to Expect

The IUI procedure is performed on an outpatient basis and does not require hospital admission. The patient is placed in a comfortable position, and the prepared sperm (approx. 0.5 to 0.6ml) is injected very slowly over 3-5 minutes using a fine cannula. This gentleness is key to avoiding trauma or regurgitation.

Timing: For optimal results, IUI is performed approximately 36 hours after the “trigger” injection or confirmation of ovulation via ultrasound.

Success Rates & Troubleshooting

While natural cycle IUI has a lower success rate (6-8%), a controlled stimulated cycle usually yields success rates between 12% to 18%. Most couples conceive within the first three cycles of treatment.

Common Concerns:

• Is it painful? Most women find it fairly painless, similar to a routine pap smear.
• Post-IUI Care: Rest for 30 minutes post-procedure is advised. There are no dietary restrictions, and normal activity can be resumed immediately.
• Side Effects: Mild cramping is the most common side effect (occurring in 5% of cases), which can be managed with simple antispasmodics.
