Hirsutizmus - patologická tvorba a distribuce ochlupení u žen - je spojen nejčastěji s nadprodukcí androgenů, ale jsou ženy s normálním profilem androgenů, u kterých je hirsutizmus přítomen a je klasifikován jako idiopatický. Často jsou přítomny anovulační cykly, ale ani ty nejsou pravidlem. Příčinu zvýšené citlivosti androgenního receptoru v kůži můžeme u postižených žen hledat v závislosti na etnickém nebo familiárním výskytu, hormonální poruše, iatrogenní příčině atd. Odpověď na androgeny je přímo ve vlasovém folikulu - androgeny jsou metabolizovány především v dermální části vlasu (tedy ve vlasové papile), jejíž buňky na rozdíl od vlasového bulbu obsahují androgenní receptory. Výskyt zvýšené tvorby ochlupení u žen je asi mezi 5-10 %. Autorka rozebírá příčiny hirsutizmu a androgenní alopecie u žen jako symptomu poruchy regulace růstu terminálního vlasu vlivem poruchy hormonální sekrece, enzymové distribuce, metabolických, nádorových a jiných stavů.

Hirsutism

Hirsutism - pathologic formation and distribution of hair in women is mostly connected with androgens overproduction. But women with normal androgen profile exist, where hirsutism is present being classified as idiopathic. Anovulation cycles are often present, but even these are not a rule. The reason for increased sensitivity of androgen receptor in the skin can be searched in ethic or familiar background, hormonal disorder, iatrogenic reason etc. Answer to androgens is present right in the hair follicle - androgens are metabolised predominantly in dermal part of a hair (hair papilla), where cells apart from hair bulbus contain androgen receptors. Increased hair formation incidence in women is about 5-10 %. Author discusses reasons of hirsutism and androgenic alopecia in women as a symptom of terminal hair growth regulation disorder based on hormonal secretion, enzyme distribution, metabolic, tumorous or other disorders.
