Intrauterine insemination (IUI) – is an injection of treated sperm into the uterine cavity. Fertilization in this case occurs naturally - this is the main difference of IUI from in vitro fertilization.
Indications for IUI on the part of male:
In the presence of serious changes in the spermogram of the spouse, which do not allow the impregnation to occur, donor sperm shall be used for fertilization.
Indications for IUI on the part of female:
Most often, the procedure of IUI shall be carried out when a female is healthy, she has pure, patulous fallopian tubes, whereas a male has a low fertilizing ability of sperm cells.
Intrauterine insemination can be performed in a natural or stimulated cycle.
When ovulation is stimulated, PR (pregnancy rate) is higher. Stimulation of ovulation shall be carried out under ultrasound control, which allows to monitor the process of ovum maturation and
increase intal uterine lining - endometrium. When reaching the most favorable moment for impregnation and implantation, sperm cells shall be injected into the uterus.
Time of ovulation shall be determined during the IUI procedure in the natural cycle using ultrasound – in most cases, it is the middle of the menstrual cycle.
After treating and concentrating male sperm during IUI procedure, it shall be injected into the uterine cavity through the cervix in the nutrient medium. The procedure is painless, since the sperm is injected with a special catheter of a very small diameter, which passes freely through the cervical canal.
The duration of intrauterine insemination is about 2 minutes. After the procedure, female shall stay in a horizontal position for 20-30 minutes.
Factors affecting the IUI effectiveness:
Factors increasing the IUI effectiveness:
Efficiency of one attempt of IUI is no more than 20%.
WHO recommends no more than six attempts of IUI, local experts tend to the fact that the maximum number should not exceed 3-4 attempts. If pregnancy has not occurred, it is recommended to undergo the procedure of in vitro fertilization (IVF/ICSI).
Preparation for IUI procedure includes the following:
