Dedjoe V. The possibilities of transvaginal ultrasonography in the diagnosis en-docrine infertility.

The studies show the effectiveness of diagnosing the different forms of endocrine infertility by way of developing a criteria of the disruption in the cyclical changes in the the follicular structure and endometrium by means of transvaginal triplex ultrasonographic monitoring Ultrasonographic criteria and the differential diagnosis were developed for dysfunctional luteal phase, premature ovarian failure, polycystic ovarian syndrome, and multifollicular ovaries. It was also established that chaotic localization of more than 12 follicles in cross section of the ovary, visualization of thickened ovarian capsule and the registration of blood flow in the follicular stroma on day 5-7 of the menstrual cycle, the absence of dominant follicle on day 11-12 of the menstrual cycle, high resistivity of intraovarial blood flow in women with normal physical structure allowed as to cocretize on the the diagnosis of secondary polycystic ovaries. Multifollicular (multicystic) ovaries are mainly characterized by oval circular forms of follicles with maturation on day 9-10 of the menstrual cycle. Criteria for luteal phase dysfunction was developed - cystic, thin-walled corpus luteum, weak vascularization with resistivity index of above 0.49, endometrial thickness less than 8 mm, 3-layed endometrium on day 21-23 of the menstral cycle.
