IUI (Intrauterine Insemination)

IUI (Intrauterine Insemination)

Artificial insemination is a technique that can help treat certain kinds of infertility problems in both men and women. In this procedure, sperm is inserted directly into a woman’s cervix or uterus. This makes the trip shorter for the sperm and bypasses any possible obstructions. Intrauterine insemination (IUI), in which the sperm is placed inside the uterus, is the most common form of artificial insemination.

Though the pregnancy rates for women undergoing artificial insemination may not be as high as they are for some more advanced techniques, this technique has a key advantage: it’s a simple procedure with few side effects. For those reasons, your doctor may recommend it as an initial form of treatment for infertility.

Intrauterine insemination (IUI) is a fertility treatment that involves placing sperm inside a woman’s uterus to facilitate fertilization. The goal of IUI is to increase the number of sperm that reach the fallopian tubes and subsequently increase the chance of fertilization.
IUI provides the sperm an advantage by giving it a head start, but still requires a sperm to reach and fertilize the egg on its own. It is a less invasive and less expensive option compared to in vitro fertilization.

The most common reasons for IUI are a low sperm count or decreased sperm mobility.

However, IUI may be selected as a fertility treatment for any of the following conditions as well:

  • Unexplained infertility
  • A hostile cervical condition, including cervical mucus problems
  • Cervical scar tissue from past procedures which may hinder the sperms’ ability to enter the uterus
  • Ejaculation dysfunction

IUI is not recommended for the following patients:

  • Women who have severe disease of the fallopian tubes
  • Women with a history of pelvic infections
  • Women with moderate to severe endometriosis

How does IUI work?

Before intrauterine insemination, ovulation stimulating medications may be used, in which case careful monitoring will be necessary to determine when the eggs are mature. The IUI procedure will then be performed around the time of ovulation, typically about 24-36 hours after the surge in LH hormone that indicates ovulation will occur soon.

A semen sample will be washed by the lab to separate the semen from the seminal fluid. A catheter will then be used to insert the sperm directly into the uterus. This process maximizes the number of sperm cells that are placed in the uterus, thus increasing the possibility of conception.

The IUI procedure takes only a few minutes and involves minimal discomfort. The next step is to watch for signs and symptoms of pregnancy.

What are the risks of IUI?

The chances of becoming pregnant with multiples is increased if you take fertility medication when having IUI. There is also a small risk of infection after IUI.

How successful is IUI?

The success of IUI depends on several factors. If a couple has the IUI procedure performed each month, success rates may reach as high as 20% per cycle depending on variables such as female age, the reason for infertility, and whether fertility drugs were used, among other variables.
