INDIVIDUAL AND CYCLIC ESTROGENIC PROFILE IN WOMAN: STRUCTURE AND VARIABILITY OF THE DATA

摘要

In premenopausal women the role of estrogens is not thoroughly understood due to the large variations in estrogenic concentration throughout the menstrual cycle [1-6]. Lifestyle factors, such as smoking, physical activity and alcohol consumption may affect menstrual cycle outcomes [7]. Vice versa, the variations could influence fertility [8], the sexual behavior [9] and some diseases, such as schizophrenia [10], stress [11], insomnia [12] and anxiety [13].
