Research in humans has long recognized a modulating role for sex hormones on fear learning. There is still not quite a consensus on what specific effects different hormones have, or what experimental paradigm properly reflects key processes of fear-related learning in near-ecological situations. Our aim with this work was to precisely tackle the influence of sex hormones and the menstrual cycle in fear memory, combining for the first time methods such as vaginal cytology analysis, liquid chromatography-mass spectrometry (LC-MS), fear-potentiated startle (FPS) and skin conductance response (SCR

The menstrual cycle exerts a modulatory effect on appetite among females, with a notable increase in appetite and food consumption observed during the pre-menstruation. This phenomenon may be attributed to an inhibitory mechanism related to food intake, although the underlying neural substrates remain elusive. This study aims to elucidate the variations in the inhibitory control for food and its associated neural correlates throughout the menstrual cycle.Eleven healthy females with regular menstruation participated in the present study. Participants were asked to visit the laboratory at four d
