Intrauterine insemination (IUI) is a method of infertility treatment. The procedure involves preparing the sperm from the husband or a donor and introducing it into the uterine cavity. Fertilization then occurs naturally.

This method of assisted reproductive technology is the simplest, requires minimal preparation, and is the most natural.

Intrauterine insemination is used when there are no significant obstacles to pregnancy: the fallopian tubes are in good condition, the uterine endometrium is ready for embryo implantation, and the sperm analysis is within normal limits.

When IUI is used:
The main indication for intrauterine insemination is cervical infertility. In this case, sperm either cannot pass through the cervix into the uterine cavity or lose their ability to fertilize the egg while passing through the cervical canal. There are other indications as well.

IUI for Female Infertility:

- Cervical factor;
- Increased acidity of the vaginal environment;
- Irregular menstrual cycle and some other endocrine factors.
IUI is also used by healthy women who do not have a partner but wish to have a child.

IUI for Male Infertility:

- Low sperm quality — sperm is prepared for IUI, which enhances its fertilization capability;
- Antisperm antibodies in the ejaculate (immunological factor of infertility);
- Inability to perform sexual intercourse for various reasons;
- High risk of passing on hereditary pathology — in this case, donor sperm is used for IUI.
