Are You Planned for IUI? Your Step-by-Step Roadmap

Intrauterine Insemination (IUI) is often the first step for many couples on their fertility journey. It is a less invasive and more affordable procedure than IVF, but its success depends heavily on precise timing and ultrasound monitoring. At Talwar Fertility & Child Health Centre, we follow a meticulous protocol to ensure the best possible outcome.

Phase 1: The Baseline Scan (Day 2)

The journey begins on the 2nd day of your menses (D2). This initial ultrasound is critical to:

• Assess the Antral Follicular Count (AFC).
• Rule out any pre-existing ovarian cysts, such as follicular or corpus luteal cysts, that might interfere with the current cycle.

Phase 2: Ovulation Induction

If the baseline scan shows an endometrial thickness of less than 4 mm and no follicles larger than 6 mm, we proceed with Ovulation Induction. Medication (Clomiphene Citrate or Letrozole) is started on Day 2 or Day 3 for five days. Depending on the patient’s profile, Gonadotrophins may also be added.

Phase 3: Follicular Monitoring

Transvaginal Sonography (TVS) begins on the 9th day of menses (D9). We track the growth of the follicles every alternate day. The goal is to identify a “Dominant Follicle.”

Phase 4: The Trigger and Insemination

Once the dominant follicle reaches a mature size of 20-22 mm, we administer a “Trigger” injection of Human Chorionic Gonadotrophin (HCG) (5000/10000 IU). This mimics the body’s natural surge that causes the egg to be released.

Why Timing is Everything

At our Gurugram clinic, we emphasize that IUI success is a science of timing. By aligning the insemination exactly with the rupture of the follicle, we maximize the chances of fertilization. If you are planned for an IUI, following this schedule precisely is the most important thing you can do.
