According to a study the incidence and prevalence of twin pregnancies have been increased from 18.9 cases per 1000 in 1980 to 32.1 cases recorded in 2005. Objective: To determine the ultrasonographic frequency of twin pregnancies in general population of district Jhang. Material and Method: This cross sectional study was carried out on a total of 100 participants for a period of three months. A convenient sampling technique was used in patients who visited the Manzoor Diagnostic Center, Jhang. Data was calculated by a specified performa and all measurements were taken by an experienced radiologist using ultrasonography. Data was analyzed by using SPSS version 20.0. Maternal age group and gestational age group and number of gestation were expressed in the form of frequency and percentage. Graphs were also used to display the data. Result: Among 100 participants The mean value of the maternal age was calculated as 26.80±3.53 with minimum age of 19 years and 33 years as maximum of age. The mean gestational age was calculated as 24.11±7.90. Single pregnancy was seen in 94% females while twin pregnancy was seen in 5% patients and only 1% female reported with multiple pregnancy status. 3% of twin pregnancies were seen in age group 23-27 following 2% in age group 28-32 years and 1% triple pregnancies were seen in age group 33-37 years.
