claim: the ace2 deficiency in sertoli cells and germ cells may cause male reproductive disorder after sars-cov-2 infection
evidence_1: moreover, the positive rate of ace2 in testes of infertile men was higher than normal, which indicates that sars-cov-2 may cause reproductive disorders through pathway activated by ace2 and the men with reproductive disorder may easily to be infected by sars-cov-2.", "the novel angiotensinconverting enzyme (ace) homolog, ace2, is selectively expressed by adult leydig cells of the testis.", "the expression level of ace2 was related to the age, and the mid-aged with higher positive rate than young men testicular cells.",
