Intrauterine Insemination (IUI) is one of the types of artificial insemination. It is a procedure for treating infertility.

Sperms that have been washed and concentrated are placed immediately in your uterus at the time when the ovary discharges one or more eggs to be fertilized. Older types of artificial insemination set the sperm in the vagina. Though this was easier, it was not as successful as the current process.

The anticipated outcome of intrauterine insemination is for the sperm to float into the fallopian tube and fertilize a waiting egg, consequent in a normal pregnancy. Depending on the grounds for infertility, IUI can be co-ordinated with the usual cycle or with fertility medications.

When is IUI used?

The most common grounds for IUI are a low sperm count or reduced sperm mobility.

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

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

IUI is not advisable for the following patients:

  • Women who have acute 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, medications to stimulate ovulation may be used, in which case cautious monitoring will be essential to determine when the eggs are mature. The IUI procedure will then be executed around the time of ovulation; typically around 24 to 36 hours after the surge in LH hormone that signifies ovulation will happen soon.
    • A semen sample will be cleansed by the lab to separate the semen from the seminal fluid. A catheter will then be utilized to insert the sperm immediately into the uterus. This process increases the number of sperm cells that are set in the uterus, thus increasing the chance of conception.
    • The IUI process takes only a few minutes and involves least discomfort. The next step is to observe for signs and symptoms of pregnancy.




What are the risks of IUI?

  • The probability of becoming pregnant with multiples is increased if you take fertility medications when having IUI. There is also a slight risk of infection after IUI.
