The goal of this study was to determine the ovarian reserve by sonographic measurement of ovarian volume and antral follicle count, then correlate with menstrual pattern in women belonging reproductive age. All patients were grouped accordingly into early, mid and late reproductive age group. Transvaginal or transrectal sonography was performed on the follicular phase of the menstrual cycle. Ovarian volumes and antral follicle counts of both ovaries were determined sonographically and recorded.

METHODS: A total of 160 subjects were included in the study. Infrequent; menstrual pattern were noted in half (50%) of the subjects. Irregular menstrual pattern were noted in more than half (55%) of the subjects. Almost 60% were noted to have shortened duration of menstrual pattern. There were 92 (57.5%) with light menstrual pattern.

RESULTS: Results showed ovarian volume and antral follicle count decreases with increasing age. Ovarian volume of subjects with infrequent menstrual pattern was significantly higher than those with frequent menstrual pattern but is significantly higher than those with normal menstrual pattern. Ovarian volume of subjects with irregular menstrual pattern were significantly higher than those with regular menstrual pattern. Antral follicle count of subjects with infrequent menstrual pattern was significantly higher than those with frequent menstrual pattern but is significantly higher than those with normal menstrual pattern. Antral follicle count of subjects with irregular menstrual pattern were significantly higher than those with regular menstrual pattern. Results showed that there was a significant difference both in the ovarian volume and antral follicle count according to age as well as frequency and regularity of menstrual pattern.
