title: Hormone receptors in pubic skin of premenopausal and postmenopausal females.
abstract: Various functions of the skin are hormone-dependent. Recently hormonal involvement in aging processes of the skin has attracted increasing interest. The rapid onset of aging of the skin from the climacterium on seems to be correlated with the decrease of estrogens. In order to evaluate hormonal stimulability of the skin a study of hormone receptors was performed in pre- and postclimacteric women. Pubic skin of a total of 106 females was obtained during gynecologic operations for determination of estrogen receptors (ER), androgen receptors (AR) and gestagen receptors (PgR) by saturation analysis. In the preclimacteric group consisting of 62 females with a mean age of 39.6 +/- (SD) 6.5 years the operations were performed in the luteal phase of the menstrual cycle. The results were compared with those of 44 postmenopausal females with a mean age of 63.2 +/- 9.4 years. AR concentrations were significantly lower in the skin of postmenopausal women. 47.4% positive findings with a mean receptor level of 15.3 +/- 33.3 fmol/mg protein were to be found against 85.2% positive AR with a mean level of 31.4 +/- 20.3 fmol/mg protein in the ovulatory cycling females. These findings were of high significance. In addition, diminished PgR in the postmenopausal group were noted for incidence and mean receptor levels. PgR were positive in 18.4% with a mean level of 34.2 +/- 72.8 fmol/mg protein versus 36.3% with a mean receptor level of 34.2 +/- 72.8 in the ovulatory group. In contrast, no significant differences between ER of premenopausal and postmenopausal skin became evident. Results of hormone receptor determinations in the premenopausal and postmenopausal group with regard to the aging process are interpreted.
