Things You Must Know About Intrauterine Insemination (IUI)

IUI, which stands for intrauterine insemination, is a way to help people get pregnant. It’s like artificial insemination. During ovulation, specially prepared sperm are placed directly into the uterus. This helps the sperm reach the egg more easily when it’s released by the ovaries. Many couples or individuals who want to have a baby use this method to increase their chances of conceiving.

What is IUI (intrauterine insemination)?

IUI, short for intrauterine insemination, is a fertility treatment where sperm is directly placed into a person’s uterus.

During natural conception, sperm has to travel a long way from the vagina, through the cervix, into the uterus, and then to the fallopian tubes where fertilization happens. However, only about 5% of sperm make this journey successfully. After an ovary releases an egg, it travels to the fallopian tube, where it meets the sperm for fertilization.

With IUI, the sperm is specially prepared to remove impurities and increase concentration, then placed directly into the uterus using a thin tube called a catheter. This way, the sperm have a shorter distance to travel to reach the egg, increasing the chances of pregnancy.

Healthcare providers often try IUI before considering more invasive and costly fertility treatments. IUI can be done using sperm from a partner or a donor. Sometimes, fertility drugs are used to stimulate egg production and increase the chances of conception during ovulation.

How long does the IUI process take?

The IUI process typically spans about four weeks, which is similar to a regular menstrual cycle, lasting around 28 days.

Here’s what happens during the process:

  • Initial Examination: Before starting IUI, you and your partner undergo a thorough examination, which may include blood tests, semen analysis, ultrasound scans, and other diagnostics to assess your fertility.
  • Medication: Some individuals may be prescribed oral fertility medications for five days or injectable medications for up to two weeks. These medications help stimulate ovulation and increase the chances of releasing multiple eggs. However, not everyone needs these medications.
  • Insemination: The insemination itself is a quick procedure. It only takes a few minutes for the healthcare provider to insert the prepared sperm into the uterus using a thin tube called a catheter. Afterward, you may be asked to lie down for about 15 minutes.
  • Pregnancy Test: You can take a pregnancy test approximately two weeks after the insemination to see if the procedure was successful.

Does IUI work?

Whether IUI (Intrauterine Insemination) is effective depends on why a person is having trouble getting pregnant. It tends to be most successful for people with unexplained infertility, or those who have problems with cervical mucus or ejaculation. However, if the infertility is due to issues like fallopian tube disorders, endometriosis, or severe sperm problems, IUI might not be the best option. In these cases, treatments like IVF (In Vitro Fertilization) may be more successful.

What’s the difference between IVF and IUI?

Intrauterine Insemination (IUI) and In Vitro Fertilization (IVF) are two methods to help people get pregnant, but they work differently.

In IUI, sperm is inserted directly into the uterus during ovulation after being collected and cleaned to improve quality. The aim is for the sperm to reach the egg more easily for fertilization.

On the other hand, in IVF, the egg and sperm are fertilized outside the body in a lab. Then, the embryo is placed into the uterus.

IUI is cheaper and less invasive compared to IVF, but it has a lower success rate per attempt.

What are the steps of IUI treatment?

Here’s what typically happens during an IUI treatment:

  • Ovulation: Your doctor needs to know when you’re ovulating to time the procedure right. This can be detected using ovulation prediction kits, blood tests for hormone levels, or ultrasound to check for mature eggs. Sometimes, you might be given a shot of medication to help your body release eggs. Ovulation usually occurs about 10 to 16 days after your period starts.
  • Semen sample preparation: On the day of the IUI, your partner provides a fresh sperm sample. If needed, the sample can be collected earlier and frozen. If you’re using donor sperm, it’s already prepared by the sperm bank. The sperm is then processed to remove any impurities and concentrate the healthy sperm in a process called “sperm washing.”
  • Insemination: The actual procedure is straightforward and quick. You lie down on the exam table, and a speculum is inserted into your vagina (like during a Pap test). Then, a thin tube called a catheter is placed through your cervix into your uterus. The washed sperm sample is then gently injected into your uterus.
  • Aftercare: After the insemination, you might be asked to lie down for a short while, typically around 10 to 30 minutes. Your doctor may also prescribe progesterone to help the lining of your uterus and improve the chances of the embryo implanting. You can take a pregnancy test about two weeks after the procedure to see if it was successful.

It’s important to talk to your healthcare provider to understand the specifics of your IUI treatment and what to expect.

How to Prepare for IUI Treatment:

Before beginning IUI treatment, several steps are typically taken to ensure everything goes smoothly:

Medical Exam and Tests: You and your partner will undergo a comprehensive medical examination and fertility tests. These may include:

  • Examination of the uterus.
  • Ultrasound scans of the uterus.
  • Semen analysis for your partner.
  • Screening for sexually transmitted infections (STIs) and other infectious diseases.
  • Blood tests to check hormone levels and overall health.

Folic Acid Supplementation: Your healthcare provider may suggest taking folic acid supplements at least three months before attempting conception or starting IUI treatment. Folic acid is often included in prenatal vitamins and helps support a healthy pregnancy.

By completing these steps, you and your partner can ensure that you’re in the best possible condition for IUI treatment, increasing the chances of success.

Final Note

If you’re finding it hard to get pregnant, don’t hesitate to talk to your doctor. Many people face challenges with fertility, but there are solutions available. IUI could be one of the options to consider. Your doctor will guide you through the various fertility treatments to find the best one for you, increasing your chances of having a successful pregnancy.
