Amayi ambiri asanabadwe nthawi zambiri amayesa tsitsi lawo, kuyesa kusintha kalembedwe kapena kupeza munthu. Pambuyo pake, zimadziwika kuti ngati mwajambulidwa mu brunette, pokhala blonde, ndiye kuti maonekedwe sangasinthe. Makhalidwe, maubwenzi ndi mabwenzi akusintha. Amayi ena amavala tsitsi lawo kuti asadabwe ndi ena, koma kuti aziwoneka bwino nthawi zonse. Komabe, amai nthawi zambiri amadzifunsa ngati lingaliro loti mimba ndi dye ndizogwirizana? Ndipo kodi ndondomeko imeneyi siidzawononge thanzi la mwanayo?
Pothandizira kuletsa kudzola tsitsi pakubereka ndi kulumidwa, dyedayo imakhala ndi mankhwala omwe amachititsa kuti mayi ndi mwanayo asamveke bwino, ngakhale kuti kalembedwe kanali kosavuta. Kuonjezerapo, zinthu zoopsa zomwe zili muzojambula zopitirira zimalowetsa thupi panthawi yamadontho. Choncho, mazira opitirira amavutitsa thupi lachikazi, kaya ali ndi pakati kapena ayi.
Kumapeto kwa zaka za zana la makumi awiri, madokotala ndi a toxicologists anayamba kukambirana nkhani za chitetezo cha mankhwala a tsitsi. Deta yofufuzira inalembedwa, iwo analankhula za zotsatira zolakwika pa thupi laumunthu la zigawo zikuluzikulu za zojambula zamitundu.

Maphunziro a kachipatala ndi a poizoni a mankhwalawa akhala akuchitika kwa zaka pafupifupi makumi awiri pa malo ambiri a khansa ndi mayunivesite ku Ulaya ndi United States. Pa kafukufuku, asayansi anafufuza, onse a zinyama za laboratory, ndi anthu omwe amagwiritsa ntchito zojambulazo za tsitsi. Asayansi anadabwa pamene zotsatirazo zinapezeka.
Malingana ndi yunivesite ya Southern California, utsi wa ndudu okha umayambitsa mavuto kuposa zikopa za zikopa.
