Virilization in post-menopausal women are rare, and the differentiation between VOT and OH, the two main causes, is difficult, as images studies are usually misleading. We studied 7 women with VOT and 7 with OH (age: 59.7±8.0 x 61.4±8.2 yo, p=0.1356, BMI: 32.2±9.4 x 29.4±4.6 kg/m2, p=0.592). All were hirsute and in all the diagnosis was histologic proven. Years post-menopause until to the diagnosis were 10.1±9.5 years for VOT and 5.8±3.9 years for OH (p=0.25). In women with VOT, ovarian volume on ultrasound was not visualized in 1 and slight unilateral enlarged in the others 6, while in the OH woman ovarian volume on was not visualized in 1, normal size in 1, unilateral enlarged in 2 and bilateral enlarged in 3.

All women had at least 1 sign of virilization. Its presence was much more common in women with VOT than in women with OH (alopecia: VOT: 7 of 7 x HO: 4 of 7; clitoromegaly: VOT: 6 of 7 x OH: 1 of 7; deepening of the voice: VOT: 7 of 7 x OH: 1 of 7 and increase muscle mass: VOT: 7 of 7 x HO: 1 of 6). A virilization index (one point for each symptoms and signs) was higher in VOT (3.7±0.7) than in OH (0.8±0.4) (p<0.001).

Testosterone (RIA, median of 2 values) was higher in VOT (516.7±270.2 ng/dL) than in OH (179.5±102.8 ng/dL) (p<0.001), but with overlap between both groups (minimal and maximal values – VOT:184 and 1,114 ng/mL; OH:103 and 503 ng/mL); 4 women with OH has a higher testosterone level higher than the minimal value observed in VOT (185 to 245 ng/mL x 184 ng/dL). DHEAS, D4, 17OPH and LH were not different between the groups (p>0.01), but FSH was significantly lower in VOT (9.8±8.7 IU/L) than in OH (42.1± 17.5 IU/L) (p=0.001). Only 1 woman in the OH group presented a concentration of FSH lower than 33 IU/L (10.5 IU/L), whereas the highest concentration of FSH observed in group VOT  group was 23.4 IU/L.
