Ding ding ding. The research articles being cited both explicitly state "sex" and make no disclaimer. The statement reads as having been added after the fact due to potential ambiguity by not explicitly stating (gender|sex) once and/or misquoting by the audience intended to be reached ("Nature says gender = sex").
