The salivary glands and salivary alpha-amylase production can be influenced by many factors, including circadian rhythms, sex, age, stress, medication, tobacco and alcohol, as well as menstrual cycle (Alagendran, Archunan, Armando, & Guzman, 2010; Rohleder & Nater, 2009). There are reports of the inefficacy of saliva from menstruated women to digest glycogen in histochemical stains. However papers studying the relationship between salivary alpha-amylase activity and the menstrual cycle do not have consensual results.engconference object
