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.

In the world of fertility, a “blocked tube” is a common diagnosis. However, when that tube is filled with fluid, it is known as a Hydrosalpinx. This condition is more than just a physical blockage; it creates a hostile environment for pregnancy that can significantly compromise IVF outcomes.

Identifying Hydrosalpinx on Ultrasound

During a Transvaginal Sonography (TVS), a hydrosalpinx presents a very specific appearance. Because the distal end of the tube is blocked, fluid accumulates and distends the tube, giving it a characteristic “retort-like” shape.

Key ultrasound observations include:

• Size: Affected tubes can reach several centimeters in diameter.
• Bilateral Presence: The condition is frequently found in both fallopian tubes.
• Visibility: Large hydrosalpinx visible on ultrasound are associated with much lower pregnancy rates than those that are small or hidden.

Why It Matters: The “Toxic Fluid” Effect

Many patients ask why they can’t just proceed with IVF if the other tube is fine or if they are bypassing the tubes entirely. The reason is the hydrosalpinx fluid itself. This fluid is embryotoxic and interferes with success in three ways:

The Impact on IVF & Pregnancy Rates

At Talwar Fertility & Child Health Centre, we counsel patients that the presence of an untreated hydrosalpinx can have devastating clinical effects:

• 50% Reduction: Both implantation and pregnancy rates are slashed by half.
• Double the Risk: The incidence of spontaneous abortion (miscarriage) is doubled compared to other causes of tubal infertility.
• Ovulatory Dysfunction: It is also associated with irregular ovulation, further hindering natural conception.

Expert Management in Gurugram

Because of these risks, we often recommend managing the hydrosalpinx (either via surgical removal—salpingectomy—or clipping) before proceeding with an embryo transfer. This simple step can double your chances of bringing a healthy baby home.
