Intrauterine insemination (IUI) is a fertility treatment designed to help couples struggling with infertility achieve pregnancy. It is one of the most commonly used assisted reproductive technologies and can be an effective option for various fertility issues. This article explores IUI in detail, explaining what it is, how it works, who can benefit from it, and what to expect during the process.
What is Intrauterine Insemination (IUI)?
IUI or intrauterine insemination is a fertility procedure that involves placing sperm directly into a woman’s uterus around the time of ovulation. The goal is to increase the chances of fertilisation by ensuring that healthy sperm are closer to the egg. This can bypass certain fertility barriers, such as low sperm count or issues with cervical mucus, which may hinder sperm from reaching the egg naturally.
How Does IUI Work?
The IUI process typically involves the following steps:
- Ovulation Monitoring
Before the procedure, doctors monitor the woman’s ovulation cycle to determine the best time for insemination. This can be done using blood tests, ultrasounds, or ovulation predictor kits. - Sperm Collection and Preparation
The male partner or sperm donor provides a sperm sample, which is then processed in a laboratory. The sperm is washed to remove impurities, dead sperm, and other substances that could hinder the fertilisation process. This also helps concentrate the healthiest sperm. - Insemination
The prepared sperm is placed into the woman’s uterus using a thin, flexible tube (catheter). This is typically done during ovulation, which is when the egg is released from the ovary and is ready for fertilisation. - Post-Insemination
After the procedure, the woman may be asked to rest briefly, but there is no need for extended bed rest. Doctors may recommend taking a blood test two weeks after insemination to determine if pregnancy has occurred.
Types of IUI
There are different variations of IUI based on the fertility issues being addressed. These include:
- IUI with Partner’s Sperm: This is the most common type, where sperm from the male partner is used.
- IUI with Donor Sperm: If the male partner has fertility issues or there is no male partner, donor sperm may be used. Sperm banks are typically used to provide sperm from anonymous or known donors.
- IUI with Ovulation Induction: In some cases, fertility medications such as Clomid or gonadotropins may be prescribed to stimulate the ovaries and increase the number of eggs produced, improving the chances of successful fertilisation.
Who Can Benefit from IUI?
IUI is often recommended for couples with specific fertility issues, such as:
- Mild Male Factor Infertility: IUI can be helpful for men with low sperm count or sperm motility issues that prevent natural fertilisation.
- Cervical Issues: Some women have a cervix that is unable to allow sperm to pass through easily, such as when there is cervical scarring or hostile cervical mucus. IUI bypasses these barriers by delivering sperm directly into the uterus.
- Unexplained Infertility: When the cause of infertility cannot be identified, IUI can still be considered as a treatment option.
- Ovulation Problems: Women who do not ovulate regularly may benefit from IUI combined with ovulation-inducing medications.
- Same-Sex Couples or Single Women: Donor sperm is used in these cases, making IUI a viable option for conception.
Success Rates of IUI
The success rates of IUI depend on various factors, including the woman’s age, the cause of infertility, the quality of sperm, and whether fertility medications are used. On average, the success rate for IUI is between 10% and 20% per cycle. For women under 35, the chances of success are generally higher, while success rates decline with age, particularly after 40.
Couples considering IUI should consult with a fertility clinic to better understand their specific chances of success, like Create Fertility, which provides valuable resources and expert advice on fertility treatments, helping individuals make informed decisions about their options.

While IUI is often the first step in fertility treatment, couples may require multiple cycles before achieving pregnancy. If IUI is unsuccessful after several attempts, other fertility treatments, such as in vitro fertilisation (IVF), may be considered.
Risks and Considerations
Like any medical procedure, IUI has some risks and considerations. These may include:
- Multiple Pregnancies: If fertility drugs are used, there is a higher chance of ovulating multiple eggs, which could result in twins or even higher-order multiples. This is a risk that needs to be discussed with a doctor before proceeding with IUI.
- Infection: While rare, there is a small risk of infection after the procedure due to the insertion of instruments into the uterus.
- Ovarian Hyperstimulation Syndrome (OHSS): If fertility medications are used, there is a slight risk of overstimulating the ovaries, which can lead to OHSS, a condition that causes swollen ovaries and can be potentially dangerous.
- Emotional Stress: The fertility journey can be emotionally challenging, especially if IUI cycles do not result in pregnancy. It is important to seek support from healthcare providers, family, and friends during this process.
Conclusion
IUI is a valuable and often successful fertility treatment that offers hope to many couples facing infertility challenges. Whether it is due to male factor infertility, ovulation problems, or unexplained infertility, IUI can be a less invasive and more affordable alternative to more advanced treatments like IVF. It is important to have open discussions with a fertility specialist to determine whether IUI is the right choice for your fertility journey.
If you are considering IUI, understanding the process, success rates, and potential risks can help you make an informed decision. Remember, fertility treatments vary greatly from person to person, and your healthcare team will guide you through the best options for your individual situation.
