title: Electrodermal activity, hormonal levels and subjective experience during the menstrual cycle.
abstract: Changes in electrodermal activity and subjective experience were studied during the menstrual cycle. Sixty-two women, grouped into menstrual, follicular, ovulatory, luteal and premenstrual phases, were presented with 15, 4-s, 80-dB, 1000-Hz tones. Psychological states and psychosomatic symptoms were tested with Spielberger's State-Trait Anxiety Inventory and a self-report questionnaire. Two estimation procedures of the hormonal phases were used: one based on the onset of menses and cycle length, and another on the basal body temperature. Subjects were grouped into low or high levels of luteinizing hormone, follicle-stimulating hormone and progesterone. There were significant increases in nonspecific response frequency, skin conductance response magnitude, skin conductance level, and a decrease in habituation rate at the ovulatory phase in comparison with luteal and premenstrual phases. No changes between the cycle phases were found in subjective experience. High follicle-stimulating hormone levels were associated with slower habituation rates and low trait-anxiety. The relationship between arousal changes and subjective experience in menstrual cycle is discussed.
