What is IUI (intrauterine insemination)?

During IUI treatment, we select a large number of sperm with good motility in the laboratory and transfer them directly into the uterus during ovulation. This allows the sperm to be closer to the egg and a larger number of healthy sperm can reach the egg, which significantly increases the chances of fertilization. IUI is a safe procedure with a very low likelihood of complications.

By carefully selecting and preparing sperm, we can increase the chances of a successful pregnancy.

When could an IUI be the right choice for you?

IUI is the first treatment option for couples whose fertility is only slightly impaired


Low sperm count

The partner's sperm quality is very low or not enough sperm is produced.


Physical impairments

IUI can help couples with physical impairments or pre-existing conditions to become pregnant.

IUI Treatment Step by Step

S 1

Fertility Check

Our fertility analysis includes various methods such as ultrasound, swab, semen analysis and diagnostic blood analysis. Using state-of-the-art laboratory technology, we provide you with optimal results that serve as the basis for your further treatment.

S 2


IUI can be performed in a stimulated or natural cycle. In a stimulated cycle, we prescribe medication to stimulate egg grwoth.

S 3

Ultrasound & Ovulation

If you are taking medication for egg maturation, regular ultrasound examinations will be carried out. Shortly before insemination, your ovulation will be triggered or, if there is no hormonal stimulation, determined using an ovulation test.

S 4


The partner's sperm are prepared at around the same time as the eggs are released from the ovaries. The best sperm are selected and injected into the uterus via a thin tube. Two weeks after insemination, a pregnancy test is performed.

Frequently Asked Questions (FAQ)

Here you will find the most important questions and answers about IUI at Cada. If your question is not answered here, please feel free to contact us directly.

What does the abbreviation IUI stand for?

The abbreviation IUI stands for "intrauterine insemination". With this method, processed sperm is inserted directly into the uterus to facilitate fertilization.

What is the procedure for an IUI?

Like all treatments at Cada, IUI is carried out according to a precise schedule:

  1. Fertility analysis: Our comprehensive fertility analysis integrates methods such as ultrasound, swab, spermiogram and diagnostic blood tests. Our state-of-the-art laboratory technology also enables precise results as a basis for your individual treatment.

  2. Start of treatment: IUI can be performed in a stimulated or natural cycle. In a stimulated cycle, medication is prescribed to stimulate egg production.

  3. Ultrasound and ovulation: During the egg maturation medication, regular ultrasound examinations are carried out. Ovulation is triggered shortly before insemination. If no hormonal stimulation takes place, ovulation is determined by an ovulation test.

  4. Insemination: The partner's sperm are processed at the same time as the egg is released. The best sperm are injected into the uterus through a thin tube. A pregnancy test is carried out two weeks after insemination.

What requirements must be met for an IUI?

Various requirements must be met for IUI. Although these vary from person to person and we will be happy to advise you individually in a consultation, we would like to mention a few possible criteria:

  1. Diagnosis of infertility: To understand the causes, a precise diagnosis of infertility is necessary.

  2. Health of the uterus: The uterus must be in a healthy condition and receptive to a possible pregnancy.

  3. Ovarian reserve: Ideally, the female partner should have a sufficient egg reserve, especially if she is younger than 35.

  4. Holistic health: The general health of the woman and her partner affects holistic health and therefore plays a major role.

  5. Sperm quality: The quality of the sperm, whether from the partner or the donor, plays a decisive role.

What are the chances of success of an IUI?

The success rate of an IUI is on average 10-20% per cycle. The individual success rate depends on the woman's age, the cause of infertility and other factors. Our specialists will be happy to provide you with a realistic assessment of your individual treatment success in a personal consultation.

How much does an IUI cost?

As IUI is minimally invasive and therefore less complex than IVF, the costs are also lower. On average, an IUI treatment with all costs (medication, consultation, examinations, etc.) costs between CHF 1,000 and 1,500. At Cada, we focus on cost transparency and also offer a fixed price for IUI treatment. This price includes all costs, pregnancy tests, consultations and analyses. This means that our patients know from the outset what costs they will incur and can go through their fertility treatment with peace of mind. For detailed information on our prices and financing options, we will be happy to advise you during an initial consultation.

When does IUI treatment make sense?

IUI treatment is usually considered when couples have minimal fertility restrictions and are looking for their first treatment option. This is particularly relevant if the sperm count is low or the quality of the sperm is very poor. In addition, IUI can be considered as a supportive measure for pregnancy in cases of physical limitations or existing health problems.

Do I have to take medication before IUI?

Not necessarily. It depends on whether the IUI is performed with or without prior ovarian stimulation. Ovarian stimulation is often performed to promote egg growth. Drugs such as clomiphene, letrozole or gonadotropins are used for this purpose. These medications contribute to egg maturation. The exact medication plan depends on the woman's individual situation and is determined by the treating doctor.

Is there an age limit for IUI treatment?

There is no clear age limit for IUI, but it is usually recommended for women under 40. Older women can consider the treatment if they are healthy. Our specialists will be happy to assess your individual circumstances and make a recommendation.

How long does the entire IUI treatment process take?

An IUI treatment takes about two to four weeks. The process may begin with ovarian stimulation over 7-10 days, followed by monitoring of egg maturation, which takes about a week. Ovulation is triggered by hormone administration, around 36 hours before the IUI. Sperm preparation takes a few hours and the IUI procedure itself only takes a few minutes. A pregnancy test can be carried out around two weeks after the IUI. As the times vary depending on the individual treatment plan, it is important to discuss the exact timing with your doctor.

What is the difference between IUI and IVF?

Intrauterine insemination (IUI) and in vitro fertilization (IVF) are both assisted reproduction methods. IUI involves the insertion of sperm into the uterus, while IVF involves fertilization outside the body. IUI is less invasive, while IVF requires more steps and laboratory work.

Does the entire IUI treatment, including preparation, take place on site at Cada?

Like all other treatments, IUI also takes place on-site at Cada. All analyses are carried out by our specialists in the Cada laboratory and the team of doctors is on hand to provide support and advice at every step. There is no need to schedule an appointment to receive information about your test results and treatment plans. The Cada app allows you to flexibly view all important information during your IUI treatment. This saves time and resources and makes your fertility treatment as comfortable as possible.
