1. Tubal A tubal infertility develops due to biological or functional pathology. Biological causes of tubal infertility are: inflammatory diseases; postpartum; postabortion; postoperative complications; fallopian tubes endometriosis. Functional tubal infertility reasons are: pathology of the neuroendocrine system for regulating reproductive function; steroidogenesis; prostaglandin involvement. 2. Peritoneal A peritoneal infertility has the same causes as tubal infertility. It is the result of adhesions caused by inflammatory diseases, surgical interventions on the genitals, and in the abdominal cavity. Endometriosis is a peritoneal disease. As a result of endometriosis, the endometrium localizes outside the uterine cavity. It happens in 5-10 women out of 100. The causes of endometriosis can be mechanical, immunological, and hormonal. To diagnose it, the doctor needs the results of the gynecological and ultrasound examinations of the patient. The pathogenesis of this disease is still not entirely clear, therefore, unfortunately, there is no single approach to the treatment. 3. Endocrine An endocrine infertility covers all forms of primary and secondary amenorrhea, follicular and luteal insufficiency, ovarian and adrenal hyperandrogenemia, hyperprolactinemia, etc. Endocrine infertility occurs in women as a result of dysfunction of the ovaries, adrenal glands, pituitary gland, or thyroid gland. The female organism does not produce enough hormones, which leads to a malfunction in the maturation of the eggs. This type of infertility is most often temporary and disappears after hormonal normalization. 4. Immunological Immunological infertility is a problem for 1 out of 5 couples. The reason lies in an autoimmune response of a female organism to sperm. The female body can produce a massive amount of antibodies and therefore kill the sperm before it can fertilize the egg. The most effective treatments are IUI insemination and IVF technology. One more type is infertility due to malformations and disorders in the reproductive system, e.g.: hymen, vagina or cervical canal atresia; acquired cervical canal fusion; vaginal aplasia; double reproductive organs (uterus and vagina); traumatic damage to the genitals; retroflexed uterus and uterine. 5. Psychogenic Psychogenic infertility results from psycho-emotional disorders and stress. It arises as a result of stress and other factors. Statistics say that at least 30% of couples cannot conceive a child as a result of psychological infertility. The fear of responsibility for the child or losing attractiveness is top-2 reasons for psychological infertility. 6. Uterine Uterine infertility form appears due to multiple degenerative changes in the endometrium, inflammatory processes, and traumatic injuries. Every third patient with primary infertility has uterine fibroids that become the main infertility reason. The diagnosis of this disease is not complicated. To detect a large and medium fibroid, a doctor needs a gynecological examination and ultrasound results. In some cases, they need to make hysteroscopy to determine the state of the endometrium. As a rule, uterine fibroids infertility is temporary, and a woman can become pregnant after the node removal. 7. Extragenital Extragenital infertility form results from somatic diseases and can directly affect the generative function or lead to hormonal disorders.
