In usual clinical conditions, depressed patients with no sexual dysfunction, after signing their consent for the dissemination of their clinical information will begin their treatment with any SSRI or a Dual antidepressant as per the best clinical decision of their treating psychiatrist. Sexual dysfunction will be identified along the 6 months of active observation. Psychiatrists will decide to change dose, augment, shift or combine antidepressants at their clinical discretion in the benefit of their patients and all clinical decisions will be recorded.Comparisons among antidepressants will be made in terms of their sexual dysfunction potentiality.
