We explored the relation between age, time since menarche, antrophometric parameters and the volume and size of uterus and ovaries in a population of 835 postmenarcheal girls. Patients were grouped in two distinct groups. First group consisted of 428 patients with irregular menstrual cycles and the second group comprised of 407 patients with regular cycles. Results of our study showed that girls with regular and irregular cycles differed in height, weight, body mass index, percentage of body fat and ovarian volumes. The size of the ovaries decreases in group of girls with regular cycles (r = 0.14; p < 0.005), while it increases in girls with irregular cycles (r = 0.15; p < 0.001). Uterine volume in all patient increases gradually with increasing age reaching consistent values at 16 years(r = 0.5; p < 0.001). Age at menarche with age, time since menarche, height, weight, body mass index and percentage body fat correlated with uterine volume. Ovarian volume correlated with weight, BMI and percentage of fat. Ovarian/uterine ratio inversely correlated with age, time since menarche, height and weight in all examined patients.
In conclusion, results of our study indicate that uterus continues to grow in postmenarchal years, with increasing height and weight of girls, regardless the regularity of cycles. Postmenarcheal girls with irregular cycles are found to have heavier figures and larger ovaries.
