The cyclic changes in the endocervix in reproductive-age women

Abstract

The article presents data on transvaginal sonographic assessment of cyclic changes in the endocervix in 78 women of reproductive age (19-35 years) without uterine pathologies. Among the examined women, 46 (59.0±5.6%) had a history of pregnancy (group I), 32 (41.0±5.6%) did not experience pregnancy (group II). The thickness of the endocervix in the late proliferative period in women of group I averaged 6.3±0.7 mm, and in group II – 9.1±1.2 mm, indicating a significant (p<0.05) difference between them . A decrease in the echogenicity of the endocervix on days 9-10 of the menstrual cycle was noted in 29 (63.0±7.1%) women in group I, and in 23 (71.9±7.9%) in group II. A moderate increase in the echogenicity of the endocervix was most often recorded on days 13-14 of the cycle - in 36 (78.3±6.1%) and 18 (56.3±8.8%) women (P<0.05), respectively. Isoechogenic endocervix was most often observed on days 21-23 of the cycle - in 26 (56.5±7.3%) and 25 (78.1±7.3%) women (P<0.05), respectively.
