双性人(Intersex people)在出生之时具有非典型的身体性别特征,这可能致使初始性别判定趋于复杂,并引发非自愿或被迫的医疗处置。[26][27]依据「支持间性青年行动计划」(Interact Advocates for Intersex Youth Inter/Act project),尽管部分双性人会使用「顺性别」这一术语,然而当该术语与双性人的情况相关联时,可能会令人产生混淆之感。[28]
「平等間性運動」(Intersex Campaign for Equality)的希達·維洛里亞(Hida Viloria)声称,身为一名出生时具备间性身体且性别认同为非二元的个体,其性别认同与其身体「相符」。这使得他们既属于顺性别者,同时又是非常规性别者。此二者在顺性别的定义中被视作相互对立,然而这也表明该术语基于二元性别模式,并未将双性人的存在纳入考量。
