Intrauterine Insemination (IUI): A Complete Guide for Patients

Intrauterine Insemination (IUI

When couples face challenges in conceiving naturally, assisted reproductive technologies offer hope and solutions. One of the most common, simple, and affordable fertility treatments is Intrauterine Insemination (IUI). If you are exploring IUI as a treatment option, this guide will help you understand the process, benefits, risks, success rates, and what to expect during your journey.

What is Intrauterine Insemination (IUI)?

Intrauterine Insemination (IUI) is a type of fertility treatment where specially washed and prepared sperm are directly placed inside the woman’s uterus during her ovulation period. This increases the chances of the sperm meeting the egg, thus improving the possibility of fertilization.

IUI is often one of the first treatment options recommended before moving on to more advanced procedures like In Vitro Fertilization (IVF).

Who Should Consider IUI?

IUI is suitable for couples and individuals facing specific fertility issues. Your doctor may recommend IUI if:

• Unexplained infertility: No clear medical reason found for infertility.
• Low sperm count or motility: When sperm quality is slightly below average.
• Cervical factor infertility: Thick cervical mucus preventing sperm movement.
• Ovulation problems: Irregular or absent ovulation.
• Mild endometriosis: In cases where fertility is affected.
• Single women or same-sex couples: Using donor sperm.

However, IUI may not be recommended if there are severe fallopian tube blockages, severe male infertility, or advanced age-related infertility.

How Does the IUI Process Work?

The IUI treatment is a step-by-step process. Here is what usually happens:

1. Initial Consultation and Tests
   • Blood tests, semen analysis, and ultrasound scans are conducted.
   • Doctors rule out issues like blocked fallopian tubes.
2. Ovulation Monitoring
   • Fertility drugs may be prescribed to stimulate the ovaries.
   • Ultrasound and blood tests are used to monitor egg development.
3. Sperm Preparation (Sperm Washing)
   • A semen sample (from partner or donor) is collected.
   • The sample is “warmed and washed” to separate healthy, motile sperm from dead or poor-quality sperm.
4. Insemination Procedure
   • A thin catheter is used to place the prepared sperm directly into the uterus.
   • The process is painless and takes only a few minutes.
5. Post-Procedure Rest
   • The patient may rest for 15–30 minutes after the procedure.
6. Pregnancy Test
   • About two weeks later, a blood test is conducted to confirm pregnancy.

Benefits of IUI

• Less invasive compared to IVF.
• Affordable and simple procedure.
• Painless with minimal discomfort.
• Shorter procedure time.
• Increases chances of fertilization in mild infertility cases.

Risks and Side Effects of IUI

IUI is generally safe but can have mild risks:

• Mild cramping or spotting after the procedure.
• Rare risk of infection.
• If fertility drugs are used, risk of multiple pregnancies (twins, triplets).
• Ovarian hyperstimulation syndrome (rare).

Success Rate of IUI

The success of IUI depends on multiple factors:

• Age of the woman: Higher success rates under 35 years.
• Cause of infertility: Best results in mild male infertility or unexplained infertility.
• Use of fertility drugs: Can increase success rates.

On average, IUI success rates per cycle are:

• 10–20% in women under 35.
• 5–10% in women over 40.

Doctors usually recommend up to 3–4 IUI cycles before considering IVF.

Cost of IUI in India

IUI is one of the most affordable fertility treatments. The average cost in India ranges from ₹3,000 to ₹10,000 per cycle, depending on the clinic, location, and whether fertility drugs are used.

Lifestyle Tips to Improve IUI Success

• Maintain a healthy weight (BMI between 18.5–24.9).
• Eat a balanced diet rich in protein, vitamins, and antioxidants.
• Avoid smoking, alcohol, and drugs.
• Manage stress through yoga, meditation, or counseling.
• Exercise regularly but avoid over-exercising.

IUI vs IVF: Which is Better?
