If you have been trying to conceive without success, chances are, you’ve come across the term IUI. It’s one of the most common and less invasive fertility treatments, and for many, it’s the first step on the assisted reproduction journey.
At Womb IVF and Fertility, we understand how overwhelming fertility treatment options can seem, especially when you’re just getting started. That’s why we’ve put together this simple, easy-to-understand guide to IUI (Intrauterine Insemination) for first-timers.
So, what is IUI?
IUI, or Intrauterine Insemination, is a fertility treatment where specially prepared sperm is directly inserted into a woman’s uterus during ovulation to improve the chances of fertilization.
The goal is simple: bring sperm closer to the egg and increase the likelihood of conception. It’s often recommended for couples facing mild infertility issues or for individuals who are using donor sperm.
Who Can Benefit from IUI?
IUI is generally a good option for:
- Women with unexplained infertility
- Men with mild male factor infertility (such as low sperm count or motility)
- Women with cervical mucus issues
- Individuals or couples using donor sperm
- Same-sex couples
- Women with ovulation disorders like PCOS (when ovulation can be induced)
Note: IUI may not be effective for women with blocked fallopian tubes or severe endometriosis. In such cases, IVF (In-Vitro Fertilization) is usually recommended.
How Does the IUI Procedure Work?
Here’s what the IUI process looks like at Womb IVF and Fertility:
- Ovulation Monitoring
Your ovulation cycle is tracked using blood tests and ultrasounds. Sometimes, ovulation induction medication (like Clomid or Letrozole) may be prescribed to stimulate egg production.
- Semen Collection and Preparation
Semen is collected from your partner or donor. It is then “washed” in the lab to remove impurities and select the healthiest, most motile sperm.
- IUI Procedure
At the time of ovulation, the prepared sperm is inserted directly into the uterus using a thin, flexible catheter. The procedure is quick, painless, and takes just a few minutes.
- Post-Procedure
You can return to your normal routine the same day. A pregnancy test is usually done about two weeks later.
Is IUI Painful?
Not at all. Most people compare the IUI procedure to a routine Pap smear. You might feel mild cramping or discomfort, but it’s generally quick and minimally invasive.
What Are the Success Rates of IUI?
Success rates can vary based on age, diagnosis, and individual health. On average:
Women under 35: 10–20% success rate per cycle
Women 35–40: 10–15% success rate
Women over 40: 5–10% success rate
Fertility medications, multiple cycles, and timing accuracy can significantly improve the chances.
