Infertility impacts millions of individuals and extends its effects to their families and communities. It is estimated that about one in six people of reproductive age globally will experience infertility at some point in their lives. But choosing the right fertility treatment can be overwhelming! With many options available, understanding the success rates of different methods is crucial.
Below we will explore the differences between Intrauterine Insemination (IUI) and In Vitro Fertilization (IVF), compare their success rates, and discuss factors influencing these rates so that you have all the knowledge you need to make the best choice for you.
What’s the Difference Between IUI and IVF?
Intrauterine Insemination (IUI)
IUI is a minimally invasive fertility treatment where sperm is directly placed into the uterus around the time of ovulation. The procedure is designed to increase the number of sperm that reach the egg, enhancing the chances of fertilization. A catheter is used to insert sperm, which is typically prepared and concentrated in a laboratory before the procedure. This process bypasses the cervix, making it easier for sperm to reach the uterus.
IUI is often recommended for couples with unexplained infertility, mild male factor infertility, or cervical mucus problems. Because the eggs don’t need to be removed from the body, the whole process is far less invasive for the woman carrying the pregnancy. IUI also costs less than IVF since no egg extraction or laboratory monitoring is needed. Typically, IUI costs range from a few hundred dollars up to about $2,000 per cycle. The price variation depends on several factors, including the fertility clinic, the type of medication used, necessary blood tests, and follow-up care.
In Vitro Fertilization (IVF)
IVF is considered the most advanced and effective among assisted reproductive technology (ART) procedures. IVF is substantially more expensive than IUI, with average costs in the U.S. falling between $11,000 and $12,000 per cycle.
The IVF process includes several steps:
- Ovarian Stimulation: Hormones are used to stimulate the ovaries to produce multiple eggs.
- Egg Retrieval: Eggs are collected from the ovaries using a minor surgical procedure.
- Fertilization: Eggs are combined with sperm in a lab dish. This can be done using conventional methods or with ICSI if needed.
- Embryo Transfer: Fertilized embryos are monitored and then transferred into the uterus with the goal of implantation.
Comparing IUI and IVF Success Rates
IUI generally has lower success rates compared to IVF. Couples undergoing IUI might require multiple cycles to achieve pregnancy, which can lead to cumulative costs approaching about half of what IVF would cost. Despite the higher upfront expense, IVF is often favored for its significantly higher success rates.
IUI Success Rates
The success of IUI is influenced by multiple factors. When the procedure is done monthly, the success rates can be as high as 20% per cycle, depending on factors such as the woman's age, the cause of infertility, and whether fertility medications were used, among other considerations.
IVF Success Rates
Success rates for IVF vary depending on several factors, with age being the most significant. Below are national averages for IVF success rates by age group:

Factors Influencing Success Rates
Several factors play a crucial role in determining the success rates of both IUI and IVF treatments. One of the most significant factors is the age of the woman undergoing treatment. Younger women generally experience higher success rates due to the better quality of their eggs. High-quality eggs and sperm are essential for successful fertilization and implantation.
Health conditions also play a significant role in fertility treatment success. Conditions such as endometriosis, polycystic ovary syndrome (PCOS), and various uterine abnormalities can hinder the effectiveness of IUI and IVF. However, don’t be discouraged because it is absolutely possible to get pregnant, even with certain conditions! Accurate diagnosis and appropriate treatment of these conditions can enhance the likelihood of a successful outcome.
Lastly, lifestyle factors can affect the success of fertility treatments. Elements such as a person's weight, smoking habits, and overall health are crucial considerations. Maintaining a healthy lifestyle can positively impact the success rates of IUI and IVF, making it important for individuals to address these factors as part of their fertility journey.
