What Is IUI?

IUI, or Intrauterine Insemination, is a fertility treatment that involves the direct placement of processed and concentrated sperm into a woman's uterus near the time of ovulation. This procedure is typically timed to coincide with the release of the woman's egg, increasing the likelihood of fertilization.

IUI is often used in cases where there may be issues with the sperm, such as low sperm count or decreased sperm motility, or when the cervical mucus presents a barrier to sperm entry into the uterus. It can also be an option for single women or same-sex female couples using donor sperm to conceive.

The procedure can be performed with or without the use of fertility medications to stimulate ovulation, which makes it a versatile and widely accessible method for individuals seeking to achieve pregnancy. 

Intrauterine Insemination (IUI) Treatment

Every year, there are a growing number of couples who seek fertility treatments. High infertility levels are of great concern across the world, including India. Recently, there has been a surge in the use of Assisted Reproductive Technologies (ART) such as Intrauterine Insemination (IUI).

Medical treatments that help infertile couples to get pregnant are highly successful and widely used these days. These treatments range from ovulation-inducing fertility drugs to ART procedures such as IUI, IVF, and ICSI (Intracytoplasmic Sperm Injection).

IUI involves the carefully timed placement of prepared sperm directly into the woman's uterus. The procedure increases the chances of fertilisation and pregnancy. The procedure can be performed with or without fertility medications to stimulate ovulation, making it a versatile and widely accessible method to help achieve parenthood.

How Intrauterine Insemination Works:
  1. Ovulation Monitoring: Before Intrauterine Insemination (IUI), the woman's ovulation cycle is closely monitored. This involves tracking hormonal levels and sometimes using ultrasound to determine the optimal time for the procedure.
  2. Sperm Preparation: The sperm sample from the male partner or a donor is processed in the laboratory to concentrate the healthy and motile sperm. This step helps ensure that only the best-quality sperm is used for insemination.
  3. Insemination Process: During IUI, the prepared sperm is placed directly into the woman's uterus through a thin catheter. This procedure is usually painless and quick, resembling a routine pelvic exam in terms of discomfort.
  4. Timing is Key: IUI is typically performed around the time of ovulation when the woman's egg is released from the ovary. This timing is crucial for increasing the chances of successful fertilization.
  5. Supportive Care: After the procedure, the woman may be advised to rest for a short period before resuming normal activities. A pregnancy test is typically scheduled about two weeks after the IUI to determine if the procedure was successful.

Benefits of Intrauterine Insemination (IUI):

The advantages of IUI treatment include its simplicity and cost-effectiveness, making it a suitable fertility treatment for various conditions such as cervical factor infertility, an ovulatory infertility, moderate male factor infertility, immunological infertility, and unexplained infertility. Additionally, IUI facilitates sperm reaching the egg more readily by reducing the time and distance required, thereby increasing the likelihood of pregnancy. 

Studies indicate that when combined with ovarian hyper stimulation, the success rate of IUI can be augmented. This treatment is particularly favoured for women under 35 with functional tubes, a shorter duration of infertility, and moderate male infertility, especially in settings with limited technology. In some cases, specialists may suggest undergoing four to six cycles of intrauterine insemination before considering IVF or other alternatives. 

Risks and Considerations:

When considering Intrauterine Insemination (IUI), it's important to be aware of certain risks and considerations:

  1. Multiple Pregnancy: One of the primary risks associated with IUI is the potential for multiple pregnancies, such as twins or triplets, due to the release of more than one egg during ovulation. This can increase the health risks for both the mother and the babies.
  2. Ovarian Hyper stimulation Syndrome (OHSS): If fertility medications are used to stimulate ovulation in combination with IUI, there is a risk of developing OHSS, which can cause abdominal discomfort, bloating, and in severe cases, fluid accumulation in the abdomen or chest.
  3. Ectopic Pregnancy: IUI slightly increases the risk of ectopic pregnancy, where the fertilized egg implants outside the uterus, typically in the fallopian tubes. This condition necessitates immediate medical intervention.
  4. Emotional Considerations: Fertility treatments can be emotionally draining, and it's important to consider the potential emotional impact of undergoing IUI, especially if multiple treatment cycles are needed.
  5. Specialist Consultation: It is crucial to consult with a fertility specialist to understand the specific risks and considerations based on individual circumstances. This can guide decision-making and ensure that all potential risks are thoroughly understood and considered.
