1 OBJECTIVE: To examine the effect of a low concentration of DHEAS on the expression of the androgen receptor, estrogen receptor alpha and beta, progesterone receptor, aromatase, 3-beta-hydroxysteroid dehydrogenase, and cyclooxygenase-2 in human preovulatory granulosa cells, and to measure their production of steroid hormones (estrone, estradiol, progesterone, androstenedione, and testosterone).

2 RESULT(S): Treatment of granulosa cells with 20 ng/mL DHEAS increased the expression of androgen receptor, aromatase, 3-beta-hydroxysteroid dehydrogenase, and cyclooxygenase-2, reduced the expression of estrogen receptor beta, and increased estrone and estradiol levels, but had no effect on progesterone, androstenedione, or testosterone levels.
