MaAntisperm antibodies (ASAs) ma antibodies anogadzirwa nemuviri wemunhu kurwisa maantigens embeu ( Krause 2017: 109 ). Kuumbwa kweASA chimwe chezvikonzero zvekushaya mbereko kana kusabereka kwemuviri: maASA anokanganisa mashandiro embeu, anochinja nzira ye acrosome reaction (AR), anokanganisa maitiro ekuberekesa, kuisa muchibereko uye kukura kwembeu ( Restrepo 2013 ), uye anokonzera kupatsanuka kweDNA ( Kirilenko 2017 ). Zvidzidzo mumhando dzakasiyana dzemhuka zvakaratidza hukama pakati peASAs nekudzikira kwembeu isati yaiswa kana mushure mekuiswa muchibereko ( Krause 2017: 164 ). Mhedzisiro yekudzivirira pamuviri yeASAs iri kudzidzwa panguva yekugadzira mushonga wekudzivirira pamuviri wevanhu ( Krause 2017: 251 ), pamwe nekuderedza nekudzora huwandu hwemhuka dzesango ( Krause 2017: 268 ).

Kubva pakati pezana remakore rechi20, pasi pechiratidzo che "dambudziko rekuwanda kwevanhu," nyika yave ichishandiswa mukushambadzira kwepasi rose kwakanangana nekuderedza zvakanyanya huwandu hwevanhu vanozvarwa uye huwandu hwevanhu. Munyika zhinji dzakabudirira, huwandu hwevanhu vanozvarwa hwatodzikira zvakanyanya pasi pehuwandu hwevanhu vanozvarwa, uye huwandu hwevanhu vakwegura hwakaenzana kana kutopfuura huwandu hwevana. Michato iri kuramba ichipera nekurambana uye ichitsiviwa nekugara pamwe chete. Kurara nevanhu vasina kuroorana, ungochani, uye nyaya dzekuchinja hunhu hwevanhu vave chinhu chikuru. Kuderera kwevanhu, kwete "kuwanda kwevanhu" kwengano, kwave chinhu chitsva chepasi rose.
