“…The mean number of measurements per pregnancy was 5.3 ± 3.2 (range, [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19]. Of the 494 (88.1%) subjects that had more than one measurement, the median times for the first and last cervical length measurements were the 19 th and 31 st weeks, respectively, and the mean interval between cervical length measurements was 2.4 ± 1.6 (range, 1-18) weeks.…”

Objectives (odds ratio (OR) 0.95 (95% CI,; P < 0.001) and by approximately 6% for each additional week at which the cervical length was measured (OR 0.94 (95% CI,; P < 0.001). ConclusionThe gestational age at which cervical length is measured is an important consideration when estimating the risk of spontaneous preterm birth in twins. The risk of preterm delivery is increased at earlier gestational ages and as cervical length decreases.

“…Cervical funneling seen at midtrimester had a high sensitivity and specificity for prediction of the preterm birth, which was higher for gestations born <32 weeks than <35 weeks (86 % and 54 %, and specificity 78 % and 82 %, respectively) [40]. Funneling is seen by transvaginal ultrasound.…”

“…The patient should be examined in the dorsal lithotomy position with an empty bladder without undue pressure on the cervix, and the examiner should wait for up to 5 minutes to note any changes in cervical length and shape. Funneling is defined as dilatation of the internal os >5 mm in width for a period of at least 3 minutes [40].…”

“…A large number of prospective studies [20][21][22][23][24][25][26][27][28][29][30] have shown the predictive value of midtrimester cervical length measurement in twin pregnancies; these data were collected in two large meta-analyses. The first meta-analysis included 21 studies, 16 in asymptomatic women and only 5 in symptomatic women; the collected data included 3,523 women.…”

Twin pregnancies are increasing. Preterm birth is a major health problem with high incidence all over the world. It is known to have a higher incidence in twin pregnancies as well as being higher in IVF/ICSI pregnancies. Prediction of preterm birth in twins through transvaginal cervical length measurement and vaginal fetal fibronectin measurement are good and well-documented methods. However, this could not be applied to IVF pregnancies. Prevention of preterm birth by administration of vaginal natural progesterone or IM synthetic progesterone injections is not effective in twins. The situation was similar with administration of progesterone to IVF twin pregnancies. Prophylactic cerclage for prevention of preterm birth in twins resulted in an increase of the incidence of preterm birth. Tocolytics also are ineffective, although nifedipine may have a role in treatment of threatened preterm birth in twins.

“…They reported that a cervical length >35 mm at 18 to 24 weeks identified pregnancies at low risk for delivery before 34 weeks. In a prospective study on 251 twin gestations, Vayssiere et al, 59 performed transvaginal ultrasound assessment of the cervix. They observed that cervical length and funneling both predicted the very preterm birth.…”
