Objective Uterine and ovarian development is influenced by both age and hormonal milieu. Sonographic assessment of normal pubertal and pre-puberty girls provides critical insights into the physiological trajectory of female gonadal maturation and its potential pathological deviations.
Methods This was a cross-sectional study conducted at Gilani Ultrasound Center, Lahore, Pakistan. The duration of the study was 9 months. Uterus length, width, height, volume, right/left ovary volume and Fundo/Cervical ratio were measured.
Results A total of 384 subjects were included in our study, categorizing them into pre-puberty (age 2-6 years), early puberty (age 7-11 years), and late puberty (age 12-18 years) groups. In the pre-puberty group (n = 111, mean age 4.29 ± 1.20 years), uterine measurements revealed a mean length of 2.95 cm, height of 0.97 cm, width of 1.41 cm, and volume of 4.82 cm³. The mean volumes of the right and left ovaries were 1.24 cm³ and 1.10 cm³, respectively, with a mean F/C ratio of 1.33. For the early puberty group (n = 99, mean age 9.15 ± 1.45 years), uterine measurements included a mean length of 4.03 cm, height of 1.22 cm, width of 1.80 cm, and volume of 12.37 cm³. In the late puberty group (n = 31, mean age 12.63 ± 1.21 years), uterine measurements showed a mean length of 5.29 cm, height of 1.82 cm, width of 2.65 cm, and volume of 31.11 cm³. The mean volumes of the right and left ovaries were 4.70 cm³ and 5.26 cm³, respectively, with a mean F/C ratio of 1.26.
Conclusion Uterine and ovarian dimensions, including volumes, correlate directly with age and pubertal status, except for the (Fundus/Cervical) ratio, which shows individual variability. This normative data could serve as a basis for the evaluation of Uterine and ovarian dimensions and volume in the local population.
