Intrauterine Insemination (IUI) is a procedure in which sperm (in some cases from a donor) are placed into the women’s uterus, near or during the ovulation period. A previously confirmed permeability of the fallopian tubes (by an hysterosalpingography -HSG-, a laparoscopy or a hysteroscopy), and a sperm preparation process made in the Andrology laboratory are required; this process increases the quality and the number of sperm that reach the fallopian tubes as well as the probabilities for pregnancy.

When is Intrauterine Insemination indicated?

There are male and female factors that make this procedure the indicated treatment. Examples are: women with ovulation disorders, women requiring medication to stimulate egg production, and cervix surgery patients which interferes with sperm entrance (cervix conization history, LLETZ, trachelectomy, etc.). In males, examples are: a low sperm count or a mild to moderate motility alteration.

How is the Intrauterine Insemination performed?

After a hormonal ovary stimulation and an ultrasonographic follow up of the follicular development and ovulation, patients are called to obtain a seminal sample which will be received and labeled with the patients’ data. This sample will be subject of an improvement procedure, and delivered to the gynecologist who, having confirmed the data of the sample, introduces the seminal sample inside the uterine cavity.

What are the results of the Intrauterine Insemination?

Results depend on the couples’ reproductive difficulty and the number of attempts that are performed. Pregnancy rates are about 20 – 25%.
