Intrauterine insemination, also known as IUI, is the first treatment that couples resort to in case of fertility issues. Its non-adhesive and high affordability make it the go-to solution compared to other reproductive technology methods, such as IVF.
However, it is important to look at the success rates of such methods to decide if they are suitable for everyone. This blog takes a deeper look at the success rates of IUI and the various factors that impact your chances of pregnancy.
What is IUI?
The IUI, or Interuterine Insemination, is a type of fertility treatment exclusively designed for couples to improve the chances of conception.
Here’s how the procedure works: the sperm is washed/rinsed, and the healthiest ones are concentrated, selected, and placed inside the uterus during the time of ovulation. This cuts short the distance traveled by sperm and increases the chances of egg fertilization. Two weeks post-insemination, a pregnancy test is done via a blood or urine test.
This treatment is most effective and a common option for couples facing any of the following:
- Male partner has mild sperm issues
- Concerns due to cervical mucus
- Unexplained fertility in women
A look at the average IUI success rates
On average, the IUI success rates fall between 10% to 20% per cycle for most couples, which means 1 in 5 IUI attempts lead to pregnancy. However, this rate may differ based on personal and medical factors.
The success rate of IUI is seen as the highest in younger women due to their increased fertility. For women under 35 years of age, the IUI success rate may be between 15% to 20% per cycle. In the case of women aged 35-40 years, the success rate falls to 10% per cycle. For women aged above 40, the rates are usually 5% per cycle.
It is worth noting that the success rates of IUI treatments can sometimes improve with each cycle. According to fertility experts, at least 3-6 rounds of IUI can be attempted before opting for advanced treatments such as IVF.
Key factors that affect the success rate of IUI
Here are the various factors that play a key role in influencing the success rate of your IUI treatments:
- Age: This is one of the most prominent factors that determines the success of your IUI. Mainly because the quantity and quality of your eggs drop with age, and so do the chances of conception. Sperm quality and shape also tend to decrease in men after the age of 40.
- Type and cause of infertility: IUI treatments have a better chance of working out if the infertility issues are mild. Women with fallopian tube damage, low fertility damage, and advanced endometriosis may not see major results. This is where IVF becomes a more suitable option.
- Consumption of fertility medications: Sometimes, doctors recommend fertility meds such as Letrozole or Clomiphene Citrate before IUI for ovarian stimulation and egg release for better chances at pregnancy.
- Sperm quality and preparation: Sperm health has major significance in the success of IUI treatments. The process involves washing the semen to remove impurities and concentrate the most active sperm. If the sperm count is low or has less motility (movement), the fertilization chances are reduced.
- Ovulation and timing: The IUI success is heavily dependent on precise timing, and therefore, the treatment must take place during ovulation. Doctors use ultrasounds and hormone tests to monitor ovulation up close. Now, if the IUI is performed too early or too late, the fertilization may not take place, leading to a failed IUI.
- Lifestyle choices: Smoking, alcohol consumption, stress, obesity, etc, can impact both egg and sperm quality. Whereas a balanced diet followed by regular exercise and low stress can significantly improve your body’s natural
- Clinic expertise and technology: A reputed fertility clinic is crucial for service quality and treatment success. Advanced lab techniques are essential for sperm washing methods, along with strict ovulation monitoring. Hence, ensure to choose a trustworthy clinic with certified doctors and high transparency.
- Number of IUI attempts: As per studies, after the first 3 attempts at IUI, cumulative pregnancy rates increase every cycle. It has also been found that within the first 4 rounds of IUI, the pregnancy chances go up to 60% to 80%. In scenarios where the treatment does not work out after several cycles, your fertility specialist may re-evaluate your IUI plan or suggest switching to IVF.
When to consider other options?
Intrauterine Insemination, or IUI, is primarily designed to address mild fertility issues and, therefore, may not be suitable for everyone, aside from the various factors that influence its success rate. In case of repeated failed IUI, you may consider IVF due to its better likelihood of leading to pregnancy.
In vitro fertilization or IVF enables doctors to directly monitor fertilization, select a healthy embryo, and transfer it to the uterus for better chances at implantation.
Conclusion
While IUI can be a reliable solution for many couples in their fertility journey. With the varying success rates and the important factors to be considered, being aware of it all can enable you to approach the right treatment solution and make an informed decision.
