Intrauterine insemination (IUI) is the simplest form of assisted reproduction. In this procedure, prepared sperm are placed directly into the uterus at the time of ovulation. This shortens the distance the sperm have to travel to the egg and is meant to increase the chance of fertilization.

IUI is considerably less invasive than IVF or ICSI, and no egg retrieval is needed. For unexplained infertility, the European professional society ESHRE recommends IUI with stimulation as the first treatment before more complex procedures are used (guideline 2023).

Who is IUI suitable for?

Insemination makes sense for:

  • Mildly reduced sperm quality: reduced motility or concentration, but still sufficient for an insemination
  • Cervical factor: when cervical mucus hinders the sperm
  • Unexplained infertility: as a first attempt at treatment, although German statutory health insurance does not name this diagnosis as a reason for insemination
  • Ovulation disorders: in combination with hormonal stimulation
  • Sperm donation: for single women or same-sex couples
  • Mild endometriosis: in early stages

IUI is not suitable for blocked fallopian tubes or severely reduced sperm quality: according to a review, the chances are reduced if fewer than 1 million motile sperm remain after preparation (Ombelet 2003). In these cases, IVF or ICSI are options instead. Age also plays a role: In the German registry, at least 2.5% of inseminations with partner sperm in women aged 40 to 44 led to a birth, and from age 38, the live birth rate after IVF was just over twice as high as after stimulated IUI in the only randomized trial (ESHRE guideline 2023). In advanced endometriosis (stage III or IV), the benefit of IUI is uncertain. If the fallopian tubes are open, a stimulated IUI can still be considered according to the ESHRE guideline (2022).

The IUI treatment process

1. Cycle monitoring or stimulation

There are two options:

  • Natural cycle: Ovulation is monitored by ultrasound and hormone tests. Suitable for a regular cycle.
  • Stimulated cycle: Tablets (clomiphene or letrozole) or low-dose injections of gonadotropins cause one to three follicles to mature. The ESHRE guideline recommends gonadotropins only at a low dose and with adequate monitoring.

2. Triggering ovulation

Once the leading follicle is mature, ovulation is triggered with an hCG injection. In a French study, the insemination took place 36 hours later (Merviel 2010). Your practice plans the exact timing.

3. Sperm preparation

On the day of the insemination, the semen sample is prepared in the lab. The most motile sperm are selected and concentrated. The result: a small amount of highly concentrated, motile sperm.

4. Insemination

The prepared sperm are placed with a thin, flexible catheter directly through the cervix into the uterine cavity. The procedure takes only a few minutes and does not require anesthesia. Many women describe it as a mild pulling sensation, comparable to a gynecological swab.

5. Waiting period and test

About two weeks after the insemination, a blood test for the pregnancy hormone hCG shows whether a pregnancy has occurred. The fertility clinic Kinderwunsch-Zentrum Hannover, for example, advises not testing before day 14 after the insemination. If you received a trigger shot containing hCG, according to the prescribing information it can affect hCG tests in blood and urine for up to 10 days, so an early test may then be falsely positive. The IVF Due Date Calculator shows when testing makes sense, in its mode for insemination.

Success rates

The success rate per IUI cycle is lower than with IVF, but the treatment is simpler, less expensive, and less burdensome:

Variant Clinical pregnancy per insemination
IUI in a natural cycle 8.6%
IUI with clomiphene 8.0%
IUI with letrozole 11.7%
IUI with FSH injections (gonadotropins) 14.5%
IUI with donor sperm 16.0%

The figures come from the German Insemination Registry (DERI) and were published in the 2024 yearbook of the German IVF Registry (Deutsches IVF-Register, D.I.R.). The partner sperm figures come from an analysis of 2020 to 2024; the donor sperm figures are from 2024. Across all variants, the rate with partner sperm in 2024 was 10.3%. Letrozole is not approved for this use in Germany and is used off label.

The chances add up over several cycles. The guidelines name three to six stimulated cycles (ESHRE 2023), and the British NICE guideline names up to four stimulated cycles or going straight to IVF (NICE 2026). Our analysis of IUI chances of success by age shows how strongly the chances depend on age, how many inseminations lead to a birth, and how they develop over several cycles.

The rates depend on age, the cause of infertility, and sperm quality. In the German registry, the clinical pregnancy rate per insemination with partner sperm was 11.3% (ages 25 to 29), 10.3% (30 to 34), 9.7% (35 to 39), and 6.4% (ages 40 to 44, 2019 to 2023). In a French study, couples had the best chances when the woman was under 30, the cause was in the cervix or in disrupted ovulation, and the man had at least 5 million motile sperm (Merviel 2010).

Costs

IUI is considerably less expensive than IVF or ICSI:

Germany

  • Reference value according to familienplanung.de: about €370 without and €670 with hormone treatment. What individual practices charge self-pay patients may differ, with examples in the article IUI costs.
  • With donor sperm: plus the costs of the sperm bank, see sperm donation costs
  • Insurance coverage: Statutory health insurance funds cover 50% of the costs, for up to eight inseminations in a spontaneous cycle (also with clomiphene) and up to three after stimulation with gonadotropins. Requirements: married, both at least 25, the woman under 40, the man under 50, own eggs and sperm only

Austria

We did not find a nationwide reference value for the cost of an insemination in Austria, like the one familienplanung.de gives for Germany. The clinic will tell you its self-pay price, and the cost calculator provides an estimate. IUI is not funded through the IVF Fund (IVF-Fonds): the IVF Fund Act (IVF-Fonds-Gesetz) covers only the methods with fertilization outside the body (Section 1, paragraph 2, items 2 to 4 of the Austrian Reproductive Medicine Act, Fortpflanzungsmedizingesetz), and according to the Austrian public health portal, IVF and ICSI are the methods that receive funding. For coverage of the cost of an insemination, gesundheit.gv.at refers to the respective social insurance carrier, so ask your health insurance fund in advance.

Switzerland

  • What a cycle costs without insurance is estimated by the cost calculator
  • Mandatory basic health insurance (Grundversicherung) covers intrauterine insemination, with a maximum of three treatment cycles per pregnancy. As with all benefits, a deductible (ordinary deductible of CHF 300 per year) and 10% co-insurance apply, with a maximum of CHF 700 per year

IUI vs. IVF: when to switch?

Criterion IUI IVF/ICSI
Invasiveness Minimal Egg retrieval required
Cost per cycle Reference value €370 without, €670 with hormones considerably higher, see IVF costs
Clinical pregnancy up to age 39 9.7% to 11.3% per insemination (ages 25 to 39), 10.3% across all age groups in 2024 31.9% to 43.1% per transfer with conventional IVF
Clinical pregnancy from age 40 6.4% per insemination (ages 40 to 44) 24.1% per transfer (age 40 only, conventional IVF)
Anesthesia Not required Brief anesthesia for retrieval
Time required Ultrasound checks and the insemination More appointments: monitoring during stimulation, egg retrieval, and transfer

The figures come from the D.I.R. yearbook 2024: IUI from the German Insemination Registry (partner sperm, 2019 to 2023), IVF from the German IVF Registry (conventional IVF, 2019 to 2023). The reference bases differ; “per transfer” leaves out cycles without a transfer. Per egg retrieval, the clinical pregnancy rate with IVF was 32.2% (up to 29), 30.3% (30 to 34), and 25.3% (35 to 39). Over the entire treatment, the gap is smaller: In a Dutch study of women aged 18 to 38 (unexplained or mild male-factor cause), 47% of couples with stimulated IUI and 52% with IVF and single embryo transfer had a healthy singleton baby within 12 months (INeS 2015).

Switching to IVF is usually a consideration in cases of:

  • Several unsuccessful cycles (ESHRE: three to six, NICE: up to four stimulated cycles)
  • Age 38 or older: Here, IVF led to just over twice as many births as stimulated IUI in the only randomized trial (relative risk 2.15; ESHRE guideline 2023)
  • Worsening semen quality
  • Newly discovered causes (e.g., a tubal factor)

Risks

IUI is a minor procedure without anesthesia. You should know about these risks:

  • Multiple pregnancies: the risk is higher in stimulated cycles because several follicles can mature. According to the German Insemination Registry (DERI), the rate of multiples after IUI with partner sperm was 1.3% in a natural cycle, 6.8% across all stimulated cycles, and 9.4% with FSH injections (2020 to 2023, reference base not stated in the yearbook). For this reason, ESHRE recommends gonadotropins only at a low dose and with adequate monitoring. Under the guideline of the Federal Joint Committee (Gemeinsamer Bundesausschuss, G-BA), an IUI covered by statutory health insurance after gonadotropin stimulation should only take place if no more than three follicles have matured, apart from medically justified exceptions.
  • Mild discomfort: mild pulling or cramping during or after the insemination is possible
  • Infections: Because the catheter is passed through the cervix, the practice works with sterile materials. The sources we reviewed do not state how often an infection occurs after an IUI. You should discuss fever or increasing lower abdominal pain after the insemination with your practice
  • Ovarian hyperstimulation: possible in stimulated cycles. The sources we reviewed do not state how often it occurs after an IUI. A low dose and ultrasound checks are meant to help avoid an excessive response of the ovaries or detect it early. If you have symptoms after stimulation, contact your practice

Frequently asked questions

Does insemination hurt?

Many women describe IUI as a mild pulling sensation, comparable to a gynecological swab. Anesthesia is not needed.

Do you have to lie down after IUI?

This is not settled. A Dutch study found more births after lying down for 15 minutes, and a later meta-analysis could not confirm this. Details under Do I have to lie down after IUI?.

Does IUI also work with donor sperm?

Yes, IUI is also possible with donor sperm; more on this under sperm donation. The thawed donor samples are prepared and placed in the same way. Success rates are higher with donor sperm (16.0% in 2024 versus 10.3% with partner sperm per insemination, according to the German Insemination Registry). The registry does not state reasons for this. Note the differences across Germany, Austria, and Switzerland (the DACH region): In Austria and Switzerland, single women have no access to sperm donation, and in Switzerland it is reserved for married couples.

How many IUI attempts make sense?

The guidelines name three to six stimulated cycles (ESHRE 2023) and up to four stimulated cycles with gonadotropins or going straight to IVF (NICE 2026). In a large Dutch study, the ongoing pregnancy rate was still 4.6% to 6.7% per cycle even in the seventh to ninth cycle (Custers 2008). In Germany, statutory health insurance pays for up to eight inseminations in a spontaneous cycle and up to three after stimulation with gonadotropins.

Conclusion

IUI is the simplest and least expensive form of fertility treatment and needs no anesthesia. In the German registry, the clinical pregnancy rate per insemination with partner sperm was 10.3% in 2024, ranging from 8.0% (clomiphene) to 14.5% (FSH injections, 2020 to 2024) depending on the stimulation, and 16.0% with donor sperm in 2024. That is considerably lower than with IVF per transfer, and the chance declines with age. IUI is suited mainly to mildly reduced sperm quality, cervical factor, unexplained infertility, or sperm donation. If it remains unsuccessful after several attempts or you are 38 or older, it is worth taking a look at IVF or ICSI.
