Natural menstrual cycle and/or oral contraception diversely affect women metabolites.
Longitudinal metabolic profiling under constant experimental conditions is thereby realistic
to understand such effects. Thus, we investigated volatile organic compounds (VOCs)
exhalation throughout menstrual cycles in 24 young and healthy women with-and without
oral contraception. Exhaled VOCs were identified and quantified in trace concentrations via
high-resolution real-time mass-spectrometry, starting from a menstruation and then repeated …
