Употребление эстрогенов положительно сказывается на лечении ага, но ведет к феминизации, необратимому бесплодию и импотенции и прочим прекрасным вещам у мужчин.

НазваниеEffects of sex steroids on skin 5 alpha-reductase activity in vitro.
ОписаниеАннотацияSkin 5 alpha-reductase activity is the major factor influencing the manifestation of androgen excess. Although oral contraceptives have been useful for the treatment of androgen excess, little is known of the independent effects of the various progestins and estrogens on inhibition of skin 5 alpha-reductase activity. We incubated minces of normal genital and pubic skin with physiologic concentrations of 3H-testosterone to assess 5 alpha-reductase activity by its conversion to 3H-dihydrotestosterone. In separate experiments, 5 alpha-reductase activity was assessed before and after the addition of progesterone, medroxyprogesterone acetate, levonorgestrel, norethindrone, 17 beta-estradiol, and ethinyl estradiol. Progesterone, levonorgestrel, and norethindrone demonstrated 97 +/- 5.3%, 47.9 +/- 6.3%, and 59 +/- 4.6% inhibition, respectively, of genital skin 5 alpha-reductase activity at 10(-4) mol/L (P less than .01). Medroxyprogesterone acetate, however, failed to affect 5 alpha-reductase activity at similar doses. Estradiol exhibited 40.8 +/- 14.2% inhibition at 10(-4) mol/L (P less than .01), whereas ethinyl estradiol at concentrations from 10(-8) to 10(-4) mol/L failed to inhibit 5 alpha-reductase activity. We conclude that progesterone and the 19-nor-derivatives inhibit 5 alpha-reductase activity at high doses, whereas medroxyprogesterone acetate does not. Therefore, the 19-nor-progestin component may expand the usefulness of oral contraceptives in the treatment of hirsutism by an inhibitory action on skin 5 alpha-reductase activity.

НазваниеPenetration and side effects of local estrogen application in alopecia androgenetica.
ОписаниеАннотацияIn 30 male patients aged 17-37 with definite androgenetic ("male pattern") alopecia (AA, telogen hair rate greater than 20%) the total urinary estrogen level was estimated before and after topical treatment: In 18 patients estrogen in a alcoholic vehicle (0.05% dienestroldiacetate) was daily applied on the scalp skin; whereas 12 patients were treated with a corresponding preparation without estrogen and served as controls. Before treatment the average estrogen level of all patients with AA was 23.3 mum/24 hrs (individual data ranged from 9.4-45.6 mum/24 hrs) and was thus slightly elevated but still within the normal range. 3 and 6 months after treatment no significant differences of the urinary estrogen level were found between the controlled patients of the two groups and, similarly, no clinical side-effects of the estrogen application (gynecomasty etc.) were recorded. It seems, on the basis of this study, that a long-term topical treatment with estrogen does not involve considerable risks regarding side-effects on male adults, in contrast to children and youngsters. On the assumption that estrogen may be effective in AA, a local mechanism of action on the hair follicle is considered.
Тип исследованияin vivo.
