IUI (Intrauterine Insemination): All you need to know

Just In

Last Updated on November 20, 2023 by Shabnam Sengupta

IUI (Intrauterine Insemination) is a fertility treatment that offers hope to couples struggling to conceive. It involves the direct placement of prepared sperm into a woman’s uterus during her fertile period. This increases the likelihood of successful fertilisation and pregnancy. This article provides an in-depth look at Intrauterine Insemination (IUI), exploring it in detail. 

What is IUI?

Intrauterine Insemination or artificial insemination is a fertility procedure. In this procedure, the doctors introduce concentrated and motile sperm into a woman’s uterus to facilitate fertilisation. The goal of Intrauterine Insemination(IUI) is to increase the number of sperm that reach the fallopian tubes, enhancing the likelihood of sperm meeting the egg and achieving pregnancy.

How IUI came to be as a fertility treatment option?

The concept of artificial insemination dates back to ancient times. However, significant progress was made in the early 20th century, developing IUI as a fertility treatment option. In the 1940s, pioneers like Dr Gregory Pincus and Dr John Rock conducted groundbreaking research on reproductive biology and hormonal treatments, paving the way for modern fertility treatments like IUI.

How is IUI done?

The IUI procedure involves several key steps. Firstly, the doctors monitor the woman’s menstrual cycle carefully to determine the optimal time for insemination. If needed, they may prescribe fertility medications to stimulate the ovaries to produce multiple eggs, increasing the chances of successful conception. Once the eggs reach maturity, a semen sample from the male partner or a sperm donor undergoes processing to isolate the healthiest and most motile sperm.

During the insemination procedure in IUI, the doctor inserts a thin, flexible catheter gently into the woman’s uterus through the cervix. They then introduce the processed sperm directly into the uterine cavity, bypassing any potential barriers and bringing the sperm closer to the egg. The whole process is relatively quick and painless, resembling a routine pelvic exam.

How IUI increases the chances of pregnancy?

IUI significantly improves the chances of pregnancy by bypassing potential obstacles that sperm may encounter in their journey toward the egg. By placing the sperm directly into the uterus, the procedure enhances the concentration and proximity of sperm to the egg, optimizing the chances of fertilization. Additionally, the procedure’s timing ensures that sperm is present in the fallopian tubes during ovulation when the egg is released, further increasing the likelihood of conception.

Who is an ideal candidate for IUI?

IUI is a suitable fertility treatment for various groups of individuals and couples facing specific challenges in conceiving naturally. Ideal candidates for the procedure include:

  • Couples with unexplained infertility: When all standard fertility evaluations yield no apparent cause for infertility, IUI may be a viable option.
  • Mild male factor infertility: Couples facing male infertility due to low sperm count, decreased motility, or abnormal sperm shape may benefit from IUI.
  • Cervical factor infertility: Women with cervical issues that hinder sperm passage through the cervix may find success with IUI.
  • Ovulation disorders: Women who experience irregular or absent ovulation can benefit from IUI when combined with ovulation-stimulating medications.
  • Mild endometriosis: IUI can be an appropriate initial treatment for women with mild endometriosis.

Why is IUI done?

IUI can address several fertility issues effectively. Some common conditions include:

An IUI cycle typically spans a few weeks and includes several stages. We have explained the timeline of an IUI cycle from start to finish below:

Stage 1: Ovulation Induction 

The first stage involves monitoring the woman’s menstrual cycle and determining the best time for the IUI procedure. If needed, the doctors may prescribe ovulation-stimulating medications to encourage the ovaries to produce multiple mature eggs. These medications may include Clomiphene citrate or gonadotropins.

Stage 2: Monitoring 

Throughout the cycle, doctors conduct regular ultrasounds and hormone level checks to monitor the growth and development of follicles (containing eggs). This monitoring helps in identifying the optimal time for the IUI procedure.

Stage 3: Insemination 

Once the follicles have reached the desired size, a semen sample is collected from the male partner or a sperm donor. The sample is then processed in the laboratory to separate healthy and motile sperm from the seminal fluid. On the day of ovulation, the doctor introduces the processed sperm directly into the woman’s uterus via a thin catheter.

Stage 4: Pregnancy Test 

Approximately two weeks after the IUI procedure, the doctors perform a pregnancy test to determine if conception has occurred.

Which factors may influence the duration of the treatment?

Several factors can impact the duration of an IUI treatment, such as:

What are the risks of IUI?

While IUI is generally considered safe, there are some potential risks and complications:

How to minimise the risks during the procedure?

To minimise the risks associated with IUI, it is essential to follow certain precautions:

  • Expert Medical Guidance: Seek treatment from a qualified fertility specialist with experience in IUI procedures.
  • Monitoring: Regular monitoring throughout the IUI treatment cycle helps identify any potential complications early.
  • Hormonal Dosage: Precise adjustment of hormonal medication dosages helps reduce the risk of OHSS.
  • Semen Analysis: Thorough evaluation of the sperm sample ensures the use of the healthiest and most motile sperm.

What is the preparation process for IUI?

Before starting on an IUI cycle, certain preparatory steps are pivotal to optimize the chances of success. These preparations include:

What are lifestyle changes that may improve the success of IUI?

Lifestyle factors play a significant role in fertility, and making certain adjustments can positively impact the success of IUI. Consider the following lifestyle changes:

Maintain a healthy diet

A well-balanced diet rich in fruits, vegetables, whole grains, and lean proteins supports overall health and fertility. Antioxidant-rich foods, such as berries and nuts, may also boost reproductive health.

Exercise regularly

Moderate and regular physical activity can enhance fertility and reduce stress. However, avoid excessive exercise, as it may negatively affect the IUI process.

Manage stress

The state of anxiety affects the success of intrauterine insemination. Engaging in relaxation techniques such as yoga, meditation, or counselling may help manage stress.

Limit alcohol and caffeine intake

Studies suggest a link between reduced fertility and excessive alcohol and caffeine consumption. Limiting these substances can benefit overall reproductive health.

Quit smoking

Smoking has detrimental effects on fertility. Quitting smoking can improve the chances of successful IUI.

Maintain a healthy weight

Both obesity and being underweight can impact fertility. Achieving and maintaining a healthy weight can optimize the chances of conception.

What are the steps of IUI treatment?

IUI involves a few steps and is typically performed within a specific window, often around 24 to 36 hours after the trigger shot or a natural LH ( luteinizing hormone) surge is detected. This timing ensures that the insemination coincides with ovulation, increasing the likelihood of successful fertilization. The steps involved are as follows:

Step 1: Ovulation Induction

Before the procedure, the woman may undergo ovulation induction, using fertility medications to stimulate the ovaries to produce multiple mature eggs. The doctor will prescribe personalised types and dosages of medications according to the woman’s specific fertility needs.

Step 2: Monitoring 

Throughout the treatment cycle, the woman’s progress is closely monitored through transvaginal ultrasounds and hormone level assessments.  The size and number of mature follicles determined through transvaginal ultrasound help determine the timing of the insemination procedure. 

Step 3: Semen Sample Collection and Processing 

On the day of ovulation or when follicles reach the desired size, the male partner or a sperm donor provides a semen sample. The sample is then processed in the laboratory to isolate the healthiest and most motile sperm.

Step 4: Insemination 

During the insemination procedure, the prepared sperm is introduced into the woman’s uterus using a thin catheter. This procedure is generally quick, simple, and relatively painless.

Step 5: Post-Insemination Care 

After the insemination, the doctor may advise the woman to rest for a short period. It is essential to follow any additional post-insemination instructions provided by the fertility specialist.

Which medications are used in IUI?

Types of medications 

medicine

Doctors may prescribe several types of medications to induce ovulation to prepare the woman for IUI:

Administration

Clomiphene citrate is typically taken orally for a specific number of days in the menstrual cycle (5-9th in most cases), while gonadotropins are administered via subcutaneous injections

Potential side effects

What are the common side effects experienced with IUI?

While IUI is generally a well-tolerated procedure, some women may experience mild side effects. Common side effects include:

One must rest and hydrate after the procedure to ease the discomfort. Also, if they experience pain and discomfort, the doctor may prescribe over-the-counter pain relievers. Lastly, if the symptoms persist, they must consult the doctor. 

What is the success rate of IUI treatment?

The success rates of IUI can vary depending on factors such as the woman’s age, the cause of infertility, and the number of cycles attempted. On average, the success rate per cycle can range from 5% to 15%, with higher success rates for couples with specific fertility issues. Remember, this number can be higher or lower depending on various factors, such as:

What to do if IUI is unsuccessful?

If an IUI cycle does not result in pregnancy, several options are available for consideration:

Reevaluating the treatment plan: The fertility specialist may review the treatment plan and make adjustments based on the individual’s response to the previous cycle.

Considering additional cycles: Depending on the fertility diagnosis and other factors, the doctor may discuss the decision to attempt additional IUI cycles or consider alternative treatments, such as IVF.

Seeking support: Coping with an unsuccessful IUI cycle can be emotionally challenging. Seeking support from a counsellor or support group can provide valuable guidance during this time.
