The study included 100 women (78, aged 19-44 and 22, aged 45-50)menstruated spontaneously and without thyroid disease, diabetes mellitus,hyperprolactinaemia, hypogonadotropic hypogonadism or polycystic ovary syndromeand any gynaecologic surgery. They all underwent sonographic measurement oftotal antral follicle (TAF) count and mean ovarian volume (MOV) on the secondor third days of menstrual cycle. Then, the women were assigned to 5 groups: group1, 19–24 years; group 2, 25–29 years; group 3, 30–37 years; group 4, 38-44years; and group 5, 45-50 years. Therewas a significant association between chronological age and TAF number (r² =0.328, p < 0.001). No significant difference was noted in TAF number amongthe first three groups (² = 0.58, p > 0.05). TAF number was significantly different between groups 3 and 4(Z: -3.463, p < 0.001), but not between groups 4 and 5 (Z: -1.698, p >0.05). There was a significantrelationship between chronological age and MOV (r² = 0.149, p < 0.001). MOVvalues did not show a significant difference among the first 4 groups(² = 0.58, p> 0.05; ² = 7.87, p > 0.05 respectively). The MOV of group 5 was significantly different from those ofgroups 1, 2, 3, and 4 (Z: -2.75, p < 0.01; Z: -4.351, p < 0.01; Z:-2.722, p < 0.01; and Z: -2.829, p < 0.01 respectively). In conclusion, theTAF count decreases significantly beginning at 38 years of age, while MOVdecreases significantly beginning at 45 years of age. Thus, there is nosignificant decrease in the ovarian follicular reserve until the age of 38years, or in the ovarian volume until the age of 45 years.  KW - Age KW - Ovarian reserve KW - Ovarian volume KW - Total antral follicle CR - Andolf, E., Jorgensen, C., Svalenius, E., Sunden, B. 1987.
