Intrauterine insemination (IUI)

The objective of Intrauterine insemination (IUI) is to respect the natural environment of the gametes as much as possible, thus promoting fertilization. This technique consists of depositing a semen sample, which has been prepared in advance in the laboratory, inside the woman’s uterus in order to increase the potential of the sperm and improve the chances of the egg being fertilised.

Ovarian stimulation and ovulation induction

During treatment, a series of 3 or 4 ultrasound scans are carried out and the amount of estradiol in the blood is determined to check that there is normal growth and development of the follicles. When we have evidence through the ultrasound scans that the follicles have reached an adequate size and number, we schedule artificial insemination around 36 hours after administering an injection of hCG which induces oocyte maturation and ovulation.

During treatment, a series of 3 or 4 transvaginal ultrasound scans are performed to check the growth and development of the follicles (follicles are fluid filled sacs in which an egg will develop). When the follicle has reached the optimum size an injection of hCG is administered to mature the egg in the follicle and time the release of the egg (ovulation) . This injection is given approximately 36 hours before insemination takes place.
