Intrauterine Insemination (IUI)

Meet the simplest treatment.

What is IUI?

Intrauterine Insemination (IUI) is a fertility treatment procedure that involves the direct insertion of sperm into a woman’s uterus during her ovulatory cycle. The goal is to increase the number of sperm that reach the fallopian tubes, thereby increasing the chances of fertilization.



How does intrauterine insemination work?

During IUI, sperm is collected, washed, and concentrated. This “enhanced” semen is then injected directly into the uterus through a small tube or catheter. IUI is often performed in conjunction with natural or stimulated ovulation.


Is ovarian stimulation necessary for IUI?

Ovarian stimulation, although mild, is often used in conjunction with IUI to increase the chances of pregnancy. This involves the use of medications to stimulate ovulation, allowing for the release of multiple eggs during a cycle.


How to prepare for intrauterine insemination?

Prior to IUI, certain tests are conducted to confirm ovulation and the health of the uterus and fallopian tubes.


IUI with frozen sperm

Frozen sperm can also be used in IUI. This can be particularly useful when the male partner is unable to produce a fresh sample at the time of IUI, or when using donor sperm. In this case, it is referred to as heterologous IUI and can be very helpful for single women, same-sex couples, or when there are male fertility issues.


What are the costs of IUI?

The cost of IUI can vary depending on the clinic and country where it is performed. Additionally, there may be additional costs for tests, ovulation monitoring, and ovarian stimulation medications. Fertilab offers a fixed price of €508.00 with the purchase of a 3xIAC package.


After the IUI procedure:

How to know if IUI was successful?

After the IUI procedure, it may take one or two weeks before a pregnancy test can be performed. Signs such as a delayed menstrual cycle or the appearance of typical pregnancy symptoms, such as tender breasts or nausea, may suggest that the IUI was successful.


What are the symptoms after IUI?

Post-IUI symptoms can vary. Some women may experience mild bleeding or cramping. Others may have early signs of pregnancy such as tender breasts, nausea, fatigue, or frequent urination.

Is it possible to have intercourse after intrauterine insemination? In general, having sexual intercourse after IUI is usually safe unless otherwise advised by a doctor. However, it is preferable to wait a couple of days after the procedure.


Is rest necessary after IUI?

Generally, a period of rest is not required after IUI. Many women return to their normal activities immediately after the procedure.

Lower abdominal pain after IUI It is normal to experience some discomfort or cramping after IUI. However, if the pain is severe or persistent, it is important to contact a doctor.


When does implantation occur?

After IUI, embryo implantation in the uterus can occur between 6 and 12 days. During this period, it is advisable to avoid taking medications or engaging in activities that could interfere with implantation.

IUI or IVF? The choice between IUI and IVF (In Vitro Fertilization) depends on many factors, including the woman’s age, sperm quality, duration of infertility, and other health issues. IUI is less invasive and less expensive, but IVF generally has higher success rates.
