Summary:
Intrauterine insemination (IUI) has been a popular fertility treatment option for couples struggling with infertility. This procedure involves placing washed and prepared sperm directly into a woman’s uterus during ovulation, increasing the chances of fertilization. In recent years, there has been an increase in the use of a syringe for IUI, also known as intracervical insemination (ICI). This method is seen as a more natural and less invasive alternative to traditional IUI. But what are the success rates of IUI with a syringe? In this blog post, we will discuss the factors that affect the success of IUI with a syringe and provide you with important information to consider before undergoing this procedure.
Factors Affecting IUI Success Rates:
1. Age: Age plays a significant role in the success of IUI with a syringe. Women under the age of 35 have a higher chance of success compared to older women. As a woman’s age increases, the quality of her eggs decreases, making it more difficult to conceive.
2. Underlying Fertility Issues: The success of IUI with a syringe also depends on the underlying cause of infertility. If the cause is due to male factor infertility, such as low sperm count or motility, the chances of success decrease. Similarly, if a woman has blocked or damaged fallopian tubes, the success rates of IUI are lower.
3. Ovulation: Timing is crucial in IUI with a syringe. The procedure must be done during the woman’s fertile window, which is usually around 24-36 hours after the luteinizing hormone (LH) surge. If the timing is off, the sperm may not reach the egg in time for fertilization.
4. Sperm Quality: The quality of sperm used in IUI with a syringe is essential for success. The sperm should be washed and prepared before insemination to remove any dead or abnormal sperm and increase the chances of fertilization.
5. Number of Attempts: The success rates of IUI with a syringe also depend on the number of attempts. The more times a couple tries, the higher the chances of success. It is recommended to undergo at least three IUI cycles before considering other fertility treatment options.
Success Rates of IUI with a Syringe:
The overall success rates of IUI with a syringe vary depending on the factors mentioned above. On average, the success rate is around 10-20% per cycle. However, when looking at specific age groups, the success rates are higher. For women under 35, the success rate can go up to 25%, while for women over 40, it drops to 5%.

The Success Rates of Intrauterine Insemination with a Syringe: What You Need to Know
Advantages of IUI with a Syringe:
1. Natural and Less Invasive: IUI with a syringe is seen as a more natural and less invasive alternative to traditional IUI. The procedure involves placing the sperm near the cervix, mimicking the natural process of conception.
2. Cost-effective: Compared to other fertility treatments, IUI with a syringe is relatively affordable, making it a popular choice for couples with limited financial resources.
3. Multiple Attempts: As mentioned earlier, the success rates of IUI with a syringe increase with the number of attempts. This procedure allows couples to try multiple times, increasing their chances of conception.
4. Low Risk of Multiple Pregnancies: Unlike other fertility treatments, such as in vitro fertilization (IVF), IUI with a syringe has a lower risk of multiple pregnancies. This is because only a small amount of sperm is used in the procedure.
Things to Consider Before Undergoing IUI with a Syringe:
1. Consult with a Fertility Specialist: It is essential to consult with a fertility specialist before undergoing any fertility treatment, including IUI with a syringe. They can assess your fertility and provide you with personalized recommendations.
2. Understand the Success Rates: As mentioned earlier, the success rates of IUI with a syringe vary depending on several factors. It is crucial to have realistic expectations and understand that the procedure may not work for everyone.
3. Be Prepared for Multiple Attempts: As with any fertility treatment, there is no guarantee of success with IUI with a syringe. It may take multiple attempts before achieving a pregnancy.
In conclusion, IUI with a syringe or ICI is a popular fertility treatment option for couples struggling with infertility. The success rates of this procedure depend on various factors, including age, underlying fertility issues, ovulation, sperm quality, and the number of attempts. It is essential to consult with a fertility specialist and have realistic expectations before undergoing IUI with a syringe. With the right approach and understanding, this procedure can help many couples achieve their dream of starting a family.
