Na none, kuri iki cyiciro, imyanya ndangagitsina yo hanze yinka cyangwa intama irashobora kugaragara nkuwabyimbye kandi ikabyimba, 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.
