Intrauterine insemination (IUI), a form of artificial insemination, enhances pregnancy chances by placing prepared sperm directly into the uterus. This differs from Intracervical insemination (ICI), where sperm is inserted into the cervix. IUI’s direct uterine approach contrasts with ICI’s simpler method, which does not involve sperm preparation or direct uterine placement.

In IUI, sperm is inserted when an ovary releases one or more eggs, aiming for fertilization in the fallopian tube, leading to pregnancy. This is in contrast to ICI, where sperm is placed in the cervix, relying on natural sperm movement towards the egg, without targeting the timing of ovulation as closely as IUI.

Intrauterine insemination (IUI) can be synchronized with a woman’s menstrual cycle or combined with fertility medications to stimulate egg production, tailored to specific infertility causes. This approach differs from ICI, where timing with the menstrual cycle is less precise and typically doesn’t involve fertility drugs to induce ovulation.

Intrauterine insemination (IUI) is used for various fertility issues. It’s effective for those needing donor sperm, experiencing unexplained infertility, endometriosis-related fertility problems, mild male factor infertility (issues with sperm quality), cervical factor infertility (problems with the cervix affecting sperm movement), ovulatory factor infertility (issues with ovulation or egg quantity), and semen allergies. IUI involves placing sperm directly in the uterus, bypassing potential obstacles to fertilization, like poor sperm quality or cervical mucus issues, enhancing the chances of pregnancy.

Intrauterine insemination (IUI) is used for various reasons:

  1. Donor Sperm: For single people or couples with male infertility, donor sperm is used. This sperm is from certified labs and is prepared for the IUI procedure.
  2. Unexplained Infertility: When the cause of infertility isn’t clear, IUI, often with medicines to stimulate egg production, is a common first step.
  3. Endometriosis: This condition affects fertility, and IUI is used alongside medication to enhance egg quality.
  4. Mild Male Infertility: If semen analysis shows issues with sperm, IUI can help by using prepared sperm that separates higher quality sperm.
  5. Cervical Factor Infertility: If there are problems with the cervix or cervical mucus that hinder sperm movement, IUI can bypass these issues by placing sperm directly into the uterus.
  6. Ovulatory Factor Infertility: For those with ovulation issues, IUI can be used to assist in conception.
  7. Semen Allergy: If there’s an allergy to semen, IUI can help by removing proteins that cause reactions, allowing for pregnancy without allergic symptoms.

Intrauterine insemination (IUI) is generally safe, but there are a few risks. These include a small chance of infection and occasional vaginal bleeding, known as spotting, caused by the catheter used during the procedure. Additionally, if fertility medications are used with IUI, there’s an increased risk of multiple pregnancies (like twins or triplets), which can lead to complications such as early labor and low birth weight.

Preparing for intrauterine insemination (IUI) involves monitoring ovulation, often using at-home tests or ultrasounds, and sometimes medication to induce ovulation. The IUI procedure, timed closely after ovulation signs, requires a prepared semen sample, either from a partner or a donor. This sample is processed to enhance sperm quality. The IUI is a brief, painless procedure done in a clinic, where the sperm is directly inserted into the uterus, increasing the likelihood of pregnancy.

In the IUI procedure, you lie on an exam table with legs in stirrups. A speculum opens the vagina for the doctor or nurse to insert a catheter carrying sperm into the uterus. After the sperm is released, the catheter and speculum are removed. You rest briefly post-procedure before resuming normal activities, with possible light spotting for a day or two.

After IUI, wait two weeks before taking a pregnancy test to avoid inaccurate results. Testing too early can lead to false negatives, where pregnancy isn’t detected yet, or false positives, especially if you’ve taken fertility drugs. A follow-up visit might include a blood test for more accurate pregnancy detection. If pregnancy doesn’t occur, IUI may be repeated, typically for 3 to 6 cycles, before considering other treatments.
