Arizona Sexual Experiences Scale (ASEX)

The ASEX is a brief, five-item self-report screening measure designed to assess sexual dysfunction in patients taking psychotropic medications, particularly antidepressants and antipsychotics. First published by McGahuey and colleagues in 2000, it rapidly measures sexual desire, arousal, penile erection (or lubrication), ejaculation (or orgasm), and satisfaction. The ASEX has become the standard tool for evaluating medication-induced sexual side effects in psychiatric and psychopharmacology research.
