When you begin your journey exploring assisted reproductive technologies (ART), the medical terminology can quickly feel overwhelming. For most patients at Ovumia Tallinn, the journey usually comes down to deciding between the two most common treatments: IUI (artificial insemination) and IVF (in vitro fertilization).
Both methods have helped thousands of couples and single women achieve their dream of parenthood, but they work in very different ways. Here is a clear guide to help you understand which treatment might be the right starting point for you.
Artificial insemination, or intrauterine insemination (IUI), is one of the most common and mild fertility treatments.
IUI can be performed in a natural menstrual cycle or alongside mild hormonal stimulation to support egg maturation. Ovulation is carefully timed using ovulation tests or trigger injection, with treatment monitored to ensure the optimal development of one to two follicles. On the day of insemination, a semen sample from a partner or donor is prepared in the laboratory so that the most motile sperm is concentrated. The prepared sperm is then placed directly into the uterus using a thin catheter, allowing fertilization to occur naturally in the fallopian tube. The procedure is quick, minimally invasive and normal daily activities can be resumed immediately afterwards.
IVF is a more advanced, highly controlled laboratory procedure where the egg is fertilized outside the body. It offers the highest success rates per cycle of any fertility treatment available today.
The woman receives hormone medication to stimulate her ovaries to mature multiple eggs. These eggs are then gently retrieved during a minor surgical procedure. In our advanced Ovumia Tallinn laboratory, our embryologists combine the eggs with sperm. Once an embryo develops, the healthiest one is transferred directly into the uterus.
IUI supports conception through the body’s natural fertilization process. For this reason, success rates per treatment cycle are lower compared to IVF, typically around 10–20%. At the same time, IUI is a gentler option: it involves fewer medications, places less physical strain on the body and is a more affordable starting point for many patients.
IVF is a more comprehensive treatment that requires greater physical, emotional and financial commitment. In return, it offers significantly higher success rates per embryo transfer, often around 30–50%, depending primarily on the woman’s age and egg quality. At Ovumia Tallinn, our doctors take the time to explain these differences clearly and openly, helping you understand the expected outcomes and choose the treatment path that offers the best balance between effort and likelihood of success for your individual situation.
Does IUI hurt? No, IUI is generally painless and feels very similar to a standard gynecological check-up or a pap smear. It takes only a few minutes.
Can we move from IUI to IVF if it doesn't work? Absolutely. Many patients start with 2 to 3 cycles of IUI. If a pregnancy is not achieved, we can seamlessly transition your treatment plan to IVF.
