Premature ovarian failure: steroid synthesis and autoimmunity

The androgen biosynthesis and autoimmunity of 25 patients with premature ovarian failure (POF) and 28 control subjects with normal cycles were examined. Serum levels of dehydroepiandrosterone sulfate (DHEAS), 17-hydroxyprogesterone (17-OHP), androstenedione, and testosterone were analyzed in POF patients with or without organ-specific autoimmunity, and the results compared with those of women with normal ovarian function. The comparative analysis elf DHEAS, 17-OHP, androstenedione and testosterone showed that POF patients Iran significantly lower values than normal women (DHEAS, androstenedione and testosterone p < 0.01, 17-OHP p < 0.05). Furthermore, we found one or more organ-specific autoantibodies in 11 patients with POF (44%), while only one woman in the control group shouted autoimmunity (antithyroid microsome) (5.5%). Only one patient had both anti-ovarian and anti-adrenal antibodies (4%). The comparison of androgen levels in POF patients with or without autoimmunity revealed a statistically significant reduction of DHEAS levels in POF patients with organ-specific autoimmunity (p < 0.01). These data reveal the reduction in androgen synthesis in POF patients, particularly in those with organ-specific antoimmunity.
