IUI – Intrauterine Insemination

Intrauterine Insemination or IUI is an infertility treatment that involves placing sperm inside a female’s uterus to facilitate fertilization. The primary purpose of this treatment is to have a pregnancy by using skill other than sexual intercourse. The purpose of IUI is to increase the quantity of sperm that reaches the Fallopian tubes and increase the chance of fertilization. For It to work, your Fallopian tubes must be open and healthy.

Before IUI, the doctor usually gives female ovulation-stimulating medicines. In which case, careful monitoring is crucial, and insemination is to coincide with ovulation – release of the eggs. Generally about 24-36 hours after the surge in LH hormone that suggests ovulation will happen soon.

A semen specimen taken after 2-5 days of abstinence from ejaculation is washed at the lab to separate the sperm from the seminal fluid. The doctor injects washed specimen of highly motile sperm either in the cervix or higher in the uterine cavity using a sterile, flexible catheter. This technique maximizes the number of sperm cells in the uterus, thus increasing the possibility of conception.

The IUI process takes solely a few minutes and entails minimal discomfort.

Suitable Candidates For IUI Procedure

  • Female Infertility: When the woman can’t release an egg regularly (ovulation) may take medications help to ovulate regularly. These women may need IUI to time insemination at about the same time as ovulation. Infertile women sometimes take medications that cause their ovaries to produce several eggs at once. These women appear to have a better chance of getting pregnant if they also have an IUI.
  • Male Infertility: When the male partner has a low sperm count or the movement of the sperm (motility) is less than ideal. IUI is useful for infertile couples because the male has problems developing an erection or being able to ejaculate.
  • Unexplained Infertility: Cases in which the standard infertility testing has not found a cause for the failure to get pregnant.
  • Single Mother: If single women want to be a mother, IUI may be helpful for her & it also helps fully for a same-sex relationship couple.
  • HIV: If a man or a woman is HIV positive.


The cost of IUI Treatment for one cycle varies from $800 to $2000 depending on other factors and one geographic area to another.

Success Rates of Intrauterine Insemination

Depends on types of partner’s fertility problems & age. If infertility is related to ovulation problems, endometriosis or unexplained infertility, then IUI may be very helpful with high success. If women are under age of 30 to 35, then chances for IUI Success are higher. It has a low success rate if women are under age of 40 to 45 or 50. IUI is also not useful for very low sperm count (low sperm counts – less than 5 million total motile sperm). In the case of frozen donor sperm, IUI may help to increase pregnancy chances.

Intrauterine Insemination is not suitable for the following patients:

  • Moderate to severe endometriosis
  • Women with a record of pelvic infections
  • Women who have severe disease of the Fallopian tubes
