IUI (INTRA UTERINE INSEMINATION)

Intrauterine insemination (IUI ) is a procedure that involves placing sperm inside a woman’s uterus to facilitate fertilization. This fertility treatment does not involve the manipulation of a woman’s eggs, and therefore is not considered an assisted reproductive technology (ART ) procedure.

What is IUI?

IUI is a fertility treatment that uses a catheter to place a number of washed sperm directly into the uterus. The goal of IUI is to increase the number of sperm that reach the fallopian tubes and subsequently increase the chance of fertilization.

When is IUI used?

IUI is a fertility treatment often selected by couples who have been trying to conceive for at least one year with no success. IUI may be selected as a fertility treatment with any of the following conditions:

  • Unexplained infertility

  • Low sperm count

  • Decreased sperm motility

  • Ejaculation failure ( because of diabetes, multiple sclerosis, spinal cord injury and retrograde ejaculation, psychological)

  • A hostile cervical condition ,such as cervical mucus that is too thick

  • Cervical scar tissue from past procedures or endometriosis

  • Mild endometriosis

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.

A semen sample will be washed by the lab to separate the semen from the seminal fluid. A catheter is used to inject the processed 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 little time and involves minimal discomfort. The next step is to watch for signs and symptoms of pregnancy.

Women under the age of 35 usually have higher rates of success than women over age 35, but the average success rate for IUI ranges from 10-20% in one cycle. With IUI, as with other methods of artificial insemination, the success rate depends primarily on the health of both the sperm and the woman.
