BACKGROUND Several studies have investigated the relationship between behavioral changes and the menstrual cycle in female subjects at a reproductive age. The present study investigated the relationship between the menstrual cycle and emotional face recognition by measuring the N170 component of ERPs. METHODS We measured N170 of twelve women in both follicular phase and late luteal phase who ...

In semantic categorization processes, individuals form a relation between perceived or imagined objects and knowledge about these objects. In the present semantic categorization study, we correlated endogenous 17-β-estradiol levels (E2) with performance as well as amplitude of theta oscillations in young women (age 23.1±3.4 years). The semantic categorization task consisted of nouns representin...

BACKGROUND Smoking is the most important modifiable cardiovascular risk factor in young women. The aim of this study was to investigate whether tobacco use influences physiological changes in endothelial function during the menstrual cycle. METHODS AND RESULTS Flow-mediated dilation (FMD) and nitro-mediated dilation (NMD) were assessed in healthy smoking and non-smoking women, by high-resolut...

We compared systemic and cervical total IgA and IgG during the menstrual cycle among 154 women who attended clinic visits at follicular/early, periovulatory/mid, and luteal/late phases of menstrual cycle. Paired serum and cervical secretions were tested at each visit for total IgA and IgG using ELISA. Geometric mean titers for systemic IgA and IgG were 1.92 and 8.25 mg/mL, respectively. There w...

While many studies of face preferences have emphasized high agreement among individuals about the types of faces they consider attractive and unattractive, other studies have demonstrated systematic variation in face preferences. Here, we review the evidence that women's preferences for masculinity, apparent health, and self-resemblance in faces change systematically during the menstrual cycle....

This study investigated the fluctuations of autonomic nervous activities during the menstrual cycle. Twenty college females were tested for cardiovascular reactivity to mental challenge during both follicular and luteal phases across two menstrual cycles. Power spectral analysis of heart rate variability (HRV) was used to examine the autonomic nervous activities. At baseline, although heart rat...

Women have periodic physiologic change of menstruation. There is a possibility to be influenced the physical and mentally in the female. It is necessary to support a comfortable life and work for female. The relationship between workload and stress that was taken the menstrual cycle into consideration had been examined on mental tasks in this research. Menstrual phase, follicular phase and prem...

To investigate the possibility that cigarette smoking and other drug use are affected by menstrual phase in smokers with Late Luteal Phase Dysphoric Disorder (LLPDD), we examined daily diaries rating menstrual symptomatology, smoking, alcohol and nonprescription drug use, and caffeine intake in nine female smokers meeting criteria for LLPDD. Menstrual symptomatology peaked during the premenstru...

Physical activity is an important physiological variable impacting on a number of systems in the body. In rodents and several species of domestic animals, levels of physical activity have been reported to vary across the estrous cycle; however, it is unclear whether such changes in activity occur in women and other primates across the menstrual cycle. To determine whether significant changes in...

Background: Although the coordinated sequence of hormonal changes during the normal menstrual cycle are well characterized, whether similar or parallel changes occur in the distribution of various electrolytes has not been clearly established. Materials and methods: This corollary follow up study on 50 healthy normal menstruating females presents variation in serum calcium, magnesium, sodium an...
