What Is IUI (Intrauterine Insemination)?

IUI is a reproductive treatment that helps sperm reach the egg. It is a simple and less invasive process than IVF. In this process, the sperm is washed, concentrated, and placed directly into the uterus during ovulation. This increases the chances of fertilization.

Doctors often recommend IUI for couples:

1. A couple who has light male infertility (low sperm count or mobility).
2. The woman has irregular ovulation due to PCOS or hormonal issues.
3. There is an unexplained infertility without any clear reason.
4. The cervix blocks sperm and prevents natural conception.

The IUI is quick, usually painless, and does not require surgery. However, it does not always guarantee pregnancy. Success depends on factors such as age, sperm quality and overall reproductive health.

How Is IUI Done?

IUI increases the probability of pregnancy. Here is how the process works:

1. Ovulation Monitoring

Doctors track ovulation to find the best time for IUI. They use:

• Ultrasound to check the growth of eggs.
• Blood tests to measure hormone levels.

Some women take medicines to help leave eggs.

2. Sperm Preparation

The sperm is collected and washed in a laboratory. It removes weak sperm and increases the number of healthy sperm. The washed sperm improves the possibility of fertilization.

3. Insemination Procedure

• The doctor places the sperm in the uterus using a thin tube.
• This step is quick and painless for most women.
• The process takes only a few minutes.

4. Post-Procedure

• You can rest for a few minutes after the procedure.
• Then, you go home and wait for the results.
• A pregnancy test is performed after two weeks.

IUI is safe and simple. But success depends on many factors.

Symptoms That IUI Has Failed

Intrauterine insemination (IUI) is a common reproductive treatment. However, it does not always lead to pregnancy. Recognizing the signs of a failed IUI can help you understand what is expected.

Menstrual period begins

If your period begins about two weeks after the IUI process, it is a clear indication that pregnancy has not occurred. This is because there is no implantation in the uterine lining.

Negative pregnancy test

A pregnancy test may confirm the post-IUI result of 14 days later. A negative result indicates that the process did not occur in pregnancy. For accurate results, it is necessary to follow your doctor’s advice at the time of this test.

Pregnancy

Early pregnancy often comes with symptoms such as nausea, breast tenderness and fatigue. If you do not experience these signs, it may suggest that IUI was unsuccessful. However, some women cannot demonstrate early symptoms even when pregnant, so this is not a certain indicator.

Spotting or light bleeding

Light bleeding or spotting may occur due to various reasons. If this occurs before your expected period, it may indicate that IUI did not work. However, spotting can also be associated with other factors, so it is best to consult with your healthcare provider for clarity.

Ovulation Issues

Going through regular ovulation is important for IUI success. Conditions including PCOS or hormonal imbalance can cause abnormal or absent ovulation. That could worsen egg quality and have an effect on fertilization.

Advanced Maternal Age

As the age of women, specifically after 35, the first-rate and amount of the eggs decline. This natural growing older process can reduce the success rate of IUI.

Blocked or Damaged Fallopian Tubes

One of the fallopian tube must be open for IUI to work. Any kind of infection, endometriosis, or previous surgery can be cause of interruption or blockage.

Thin or Unreceptive Uterine Lining

A healthy uterine lining is important for embryo implantation. Even previous surgery, low estrogen levels, or infections can lead to a thin or unique lining can be reason for failure.

Endometriosis

It happens when the tissue similar tot he uterine lining grows outside the uterus. Having such condition can intervene with sperm movement and implantaion reducing the success rate of IUI.

Timing Issues with Sperm Injecation

Knowing the right time of ovulation is important. As inserting sperm either before that or later can also affect the chances of IUI success.

Lifestyle Factors

Smoking, consuming excessive alcohol or even obesity and high stress levels affect fertility. Having a healthy lifestyle can help in such conditions.

Number of IUI Cycles Attempted

With the increase in IUI cycles, number after a failure can also increase the chances of IUI success. Yet, if various failed attempts it is best to consider other alternatives such as IVF.
