Curious about how fertility drugs can help in your journey to parenthood? The medications involved in intrauterine insemination (IUI) have opened new possibilities if you’re hoping to start or grow your families.
If you’ve ever wondered how these treatments work and whether it’s for everyone, this guide can help to shed a light on the process.
What is IUI?
IUI is a type of fertility treatment that helps to increase your chances of pregnancy by placing your partner's sperm directly into your womb. This procedure is less invasive and more cost-effective compared to other fertility treatments, such as in vitro fertilisation (IVF).
IUI is usually recommended as part of initial treatment for couples facing unexplained infertility, reduced sperm fertility, reduced sperm count, or cervical complications. To increase the chance of conception, this treatment is usually performed during your natural ovulation or with superovulation with intrauterine insemination (SO-IUI).
In SO-IUI, medications are used to stimulate the ovaries to release two to three mature eggs instead of one, which increases the likelihood of fertilisation.
At the time of ovulation, a specially prepared sperm sample is placed directly in the uterus using a thin IUI catheter, maximising the chance for a successful conception. This combined approach is particularly beneficial for couples facing unexplained infertility, mild male factor infertility, or ovulatory disorders.
Afterwards, you can take a pregnancy test two weeks after your IUI procedure. Testing earlier can lead to inaccurate results. For example, it may produce a false negative, indicating no pregnancy, when one may actually exist. This is because the pregnancy hormone, human chorionic gonadotropin (hCG), might not have reached detectable levels in the body yet.
Role of medications in IUI
Fertility medications play a vital role in many IUI cycles. Fertility doctors often recommend them to stimulate the ovaries, encouraging the development and release of eggs. This approach is sometimes called a controlled ovarian hyperstimulation, ovulation induction, or superovulation cycle. By prompting the ovaries, medications can increase the number of eggs released, thus improving the odds of conception.

Common types of medications used in IUI
An oral medication that tricks the body into producing more hormones to stimulate egg development.
Letrozole (Femara):
Another oral medication that works differently but also stimulates the ovaries to grow eggs.
Gonadotropins (e.g., Menopur, Gonal-f, Follistim):
Injectable hormones used if oral medications are unsuccessful or unsuitable. These more closely mimic the body’s natural fertility hormones and are sometimes used in more challenging cases.
Human Chorionic Gonadotropin (hCG) Trigger Shot (Ovidrel):
hCG injections are administered to trigger the release (ovulation) of mature eggs at precisely the right time for insemination.
Are medications always necessary for IUI?
No, medications aren’t mandatory for every IUI cycle. You can opt for “natural” IUIs, relying on the body’s natural ovulation without any additional drugs. However, those with irregular ovulation or experiencing unexplained infertility are more likely to benefit from medication. Your fertility doctor will recommend the best approach based on your unique situation.
If you are considering IUI but are unsure whether you need to take fertility medications, it is best to visit your nearest fertility clinic and discuss the options with a fertility specialist. Request an appointment with Thomson Medical today.
Factors affecting medication selection
Several factors shape which medications are used, such as:
Age and ovarian reserve
Cause of infertility
Regularity of menstrual cycles
Previous responses to fertility drugs
Risk tolerance for side effects, including multiple births
Personal medical history
The choice between oral and injectable medications, or combining both, is tailored to your unique individual needs.
Risks and side effects of IUI medications
Although IUI medications are generally considered safe, they can cause the following side effects:
Hot flushes, headaches, mood swings
Bloating, breast tenderness, nausea
Mild pelvic cramping or spotting
Emotional stress, which many find as challenging as physical symptoms
However, there may also be rare side effects, such as changes to your vision, ovarian cysts, ovarian hyperstimulation syndrome (OHSS), and an increased risk of multiple pregnancies (twins or more). Your fertility specialist will monitor your progress and tweak your medication doses to minimise risks.
FAQ
How is the effect of IUI medications monitored?
Doctors track your body’s response through blood tests and transvaginal ultrasounds. These monitor follicle (egg) growth and help time the IUI procedure precisely. Monitoring also helps prevent overstimulation and reduces the risk of multiples or OHSS.
How long do I need to take medications before an IUI procedure?
You’ll typically start oral medications like Clomid or Letrozole early in your menstrual cycle (days 2-5), taking them for five days. Injections may be started around the same time and continue until follicles are mature. The total duration varies, often spanning 7-14 days.
Will I need medication in every IUI cycle?
Not necessarily. Some people use medication for each attempt, while others try natural cycles, especially if medications cause problems or aren’t needed for ovulation. Your doctor’s approach will match your health, history, and fertility goals.
Can IUI medications be used for people with irregular periods?
Yes. In fact, medications are especially helpful if you have irregular or infrequent periods, as they can help induce and time ovulation, improving your chances of successful insemination.
Are there alternatives to medications during IUI?
Yes, natural IUI (no ovulation-stimulating drugs) is an option for those who ovulate regularly or in some cases where medication is inadvisable. Discuss with your doctor what’s safest and most effective for you.
Are IUI medications the same as IVF medications?
Some are similar, especially the injectable gonadotropins and trigger shots, but IVF typically requires higher medication doses and more intensive hormonal stimulation. IUI uses less aggressive protocols, focusing on stimulating ovulation rather than egg retrieval as in IVF.
