Intrauterine insemination (IUI)

A simple, minimally invasive procedure: we place a prepared sperm sample directly into the uterus during your fertile window.

What is intrauterine insemination?

IUI consists of preparing a semen sample in the laboratory to select the sperm with the best motility and placing them directly into the uterus, near the time of ovulation. It is less complex than in vitro fertilization and is often a first option in selected cases.

Before starting any treatment, an assessment by a health professional is required to determine whether IUI is suitable for your case.

FAQ

Common questions about IUI

Is it painful?

It's usually well tolerated and doesn't require sedation. Some people feel mild discomfort, similar to a gynecological exam.

How many attempts are recommended?

It depends on each case. Your specialist will assess it with you; there's no single figure valid for everyone.

What's the difference from IVF?

In IUI, fertilization happens inside the body; in IVF, in the laboratory. The choice depends on your diagnosis.

Sample preparation in the laboratory

Laboratory preparation

The sample is carefully processed and prepared in the laboratory to perform the insemination at the optimal moment of your cycle.
