Na none, kuri iki cyiciro, imyanya ndangagitsina yo hanze yinka cyangwa intama zirashobora kugaragara ko zabyimbye kandi zabyimbye, mugihe urukuta rwigituba ruba rutose kandi rukayangana. Iyo estrus irangiye, ingano ya mucus iragabanuka kandi igahinduka ibicu na gelatine mu bigaragara. Kubyimba kw'imyanya ndangagitsina yo hanze bitangira kugabanuka, bitera iminkanyari nkeya.

Mu gusoza, inka n’intama byangiza ibyara nigikoresho gikomeye kandi cyizewe cyo gukora ibizamini byo mu nda ibyara kugirango harebwe inzinguzingo zinka n'intama. Igishushanyo cyacyo cyizengurutse gitanga umwanya wo kurinda urukuta rwimbere rwimbere rwinkondo y'umura, bigatuma inzira yo gusuzuma yitonze kandi itekanye.
