What Is IUI and How Does It Work?

Intrauterine insemination (IUI) is one of the most commonly used and least invasive forms of assisted reproductive technology (ART). The procedure involves preparing and concentrating sperm, then placing it directly into the uterus during ovulation. This increases the number of healthy sperm that reach the fallopian tubes, improving the chances of fertilization.

At GP-Fertility, IUI is often recommended as a first-line treatment—or as part of a broader, personalized fertility strategy.

When Is IUI Recommended?

IUI may be a suitable option for individuals and couples facing a range of fertility challenges, including:

• Unexplained infertility
• Mild male factor infertility
• Cervical factor infertility
• Ovulation disorders such as PCOS
• Endometriosis (mild cases)
• Use of donor sperm
• Single intended parents and same-sex couples

As part of a global care model, GP-Fertility evaluates whether IUI is the most appropriate starting point—or if more advanced treatments such as IVF may offer higher success rates based on your individual profile.

The IUI Process: Step by Step

1. Ovulation Monitoring

Your cycle is carefully tracked using ultrasound and hormone testing to identify the optimal timing for insemination.

2. Ovulation Stimulation (Optional)

Medications may be used to stimulate the ovaries and increase the number of mature eggs released, improving success rates.

3. Sperm Collection & Preparation

Sperm is collected from a partner or donor and processed in the laboratory to select the highest-quality sperm.

4. Insemination Procedure

A thin, flexible catheter is used to place the prepared sperm directly into the uterus. The procedure is quick, minimally invasive, and typically painless.

5. Pregnancy Testing

A pregnancy test is performed approximately two weeks after the procedure to determine if implantation has occurred.

Benefits of IUI

• Minimally invasive compared to IVF
• Lower cost and accessible entry point
• Short treatment cycle
• Can be combined with ovulation stimulation
• Effective for selected fertility conditions

Risks and Considerations

While IUI is generally safe, some potential risks include:

• Mild cramping or spotting after the procedure
• Low risk of infection
• Increased chance of multiple pregnancy (when using stimulation medication)

IUI Success Rates: What Affects Your Chances

Success rates vary depending on several key factors:

• Age �C Women under 35 typically have higher success rates.
• Cause of infertility �C IUI is most effective for mild or unexplained infertility.
• Use of stimulation �C Ovulation stimulation can improve outcomes in certain cases.
• Sperm quality �C Higher sperm count and motility increase the likelihood of success.
• Lifestyle factors �C Healthy habits such as balanced nutrition, regular exercise, and avoiding smoking or alcohol can positively impact results.
