Success of fertilization and its association with the levels of psychophysiological stress before and during the treatment.

Despite the advance of assisted reproduction, high rates of failure in treatment are still observed. Herein, we investigated how the psychophysiological stress profiles of patients can modulate the fertilization treatment (IVF) outcome. The women who had failure in IVF ( = 13; 65%) had higher baseline salivary cortisol awakening response and anxiety-state during treatment than patients who became pregnant ( = 7; 35%).
