Intrauterine insemination

Intrauterine insemination, or IUI, is a simple and safe procedure, and it is often one of the first fertility treatments for couples looking to fulfill their desire to have a child. It relies on the natural ability of sperm to fertilize an egg in the fallopian tube. Studies show that the effectiveness of this procedure is limited if the quality of the partner’s sperm is altered. A sperm analysis prior to the procedure is therefore relevant, as it will confirm the quality of the male partner’s sperm.

Sperm preparation for IUI takes just a few hours. The procedure is organized around the patient’s ovulation to optimize the chances of pregnancy, and involves depositing an enriched sperm preparation in the uterus. This is a painless gynecological procedure that requires no anesthesia.

The aim of this treatment is to significantly increase the number of motile spermatozoa reaching the fallopian tube, thereby increasing the chances of fertilization. This method in no way interferes with the fertilization process.

Insemination in practice

At the start of the procedure, a personalized care plan is defined with the treating gynecological specialist.

During ovulation in a natural cycle, a woman generally releases an egg from her ovaries. To increase the chances of fertilization and pregnancy by intrauterine insemination, the patient takes medication at the start of her menstrual cycle to improve and synchronize oocyte growth and maturity. This is monitored by a specialist gynecologist who will follow you throughout the first phase of your cycle.

This monitoring is carried out under ultrasound. Occasionally, blood hormone levels may be useful. When ovulation approaches, it can be triggered by medication, and intrauterine insemination can then be organized. Intrauterine insemination takes place 24 to 36 hours after ovulation.

Sperm preparation
When insemination is scheduled, a semen sample is prepared in the laboratory. The purpose of this preparation is manifold. Firstly, the seminal fluid (liquid from gland secretions) is eliminated, and the most motile spermatozoa are selected.

Finally, a preparation enriched with motile spermatozoa is obtained. This sperm preparation is used for insemination.
Intrauterine insemination
This relatively simple procedure involves depositing the sperm preparation into the uterus. This gynaecological procedure takes around twenty minutes, including the rest period. You can then resume your daily activities.
Pregnancy test
This takes place around 2 weeks after insemination. A simple blood test measures the presence or absence of βhcg, the pregnancy hormone.
