One of the most common fertility treatments a couple may choose is IUI. Intrauterine insemination (IUI) is a fertility treatment used for couples who have unexplained infertility, mild male factor infertility, or mild endometriosis.

Read on to learn about the success rates of IUI and what it can do for you.

What is intrauterine insemination?

Intrauterine insemination (IUI) is a fertility treatment used for couples who have unexplained infertility, mild male factor infertility, or mild endometriosis. This treatment involves washing sperm and inserting it directly into the uterus through the cervix. The main goal is to increase the number of sperm that travel up to meet and fertilize an egg. When sperm has been washed, it takes on a milky white color.

How does IUI work?

IUI does not require surgery or medications. Instead, the female partner takes fertility drugs such as clomiphene citrate and follicle-stimulating hormone (FSH) to stimulate her ovaries to produce several eggs. The male partner provides a semen sample that is processed to be concentrated with sperm to a higher level. This semen is then inserted directly into the female partner’s uterus during ovulation.

The success rates of IUI vary depending on the type of infertility, the age of the couple, and many other factors. According for the Mayo Clinic, about half of all couples using IUI will achieve pregnancy in one year of treatment.

Success rates of IUI

IUI is a type of fertility treatment that involves inserting sperm directly into a woman’s uterus. During IUI, the doctor may also use one or more fertility drugs.

The success rates depend on a number of factors, including:

  1. -Age of woman
  2. -Endometriosis
  3. -Male factor infertility
  4. -Type of IUI procedure
  5. -Timing of IUI in relation to ovulation
  6. -Sperm count and quality

What are the disadvantages of IUI?

There are some disadvantages to IUI. One of the most common is that it can be costly. In addition, there is a risk of multiple births so you should know what your fertility doctor’s policies are on that.

IUI also does not work for everyone which means there may be other treatments you’ll need to consider.


Intrauterine insemination, or IUI, is a procedure that involves placing sperm directly inside the uterus, or womb, with the goal of improving pregnancy rates in women with infertility issues. IUI is often used in cases where the woman has blocked or damaged fallopian tubes.

The procedure is often done using a catheter inserted through the cervix, and semen is collected in a laboratory and processed. Once the sperm is prepared, it is placed inside a small plastic catheter that is inserted into the uterus. The IUI procedure typically takes between 10 and 20 minutes.

One of the major disadvantages of IUI is that you need to be monitored closely in order to catch any complications that may arise. The procedure can also be expensive and many insurance companies don’t cover the costs of IUI treatment.

There are also several success rates associated with IUI treatment. While one study found that 54% of women who underwent IUI treatment became pregnant, other research has found success rates to be much lower – with only a handful of pregnancies occurring out of every 100 treatments. However, these numbers vary depending on what kind of fertility issues are being treated and the individual circumstances.
