The purpose of this study was to determine if the menstrual cycle influences the amplitude of transient (TEOAEs) and distortion-product (DPOAEs) otoacoustic emissions. Thirteen normal-hearing, normal-cycling females were monitored weekly for 12 weeks. TEOAE and DPOAE amplitudes were analyzed to determine if amplitude changes could be detected and correlated to phases of the menstrual cycle. No ...

Dr. L. Altshuler (University of California Los Angeles School of Medicine) and colleagues studied 72 women with bipolar disorder ages 18–45, who were not taking oral contraceptives, agreed to fill out questionnaires about their menstrual cycle, and agreed to give blood samples to measure a range of reproductive endocrine and metabolic hormone levels. Dr. Altshuler and colleagues found that seve...

New models for menstrual cycle-related mood disorders provide unique opportunities to gain insight into the processing of emotional information and the regulation of mood state by reproductive steroids. This paper reviews the role of reproductive steroids in affect regulation and in premenstrual dysphoric disorder (PMD), parses PMD into component processes that suggest potential mediating neuro...

STUDY QUESTION Does perfluorooctane sulfonate (PFOS) and perfluorooctanate (PFOA) exposure disrupt the menstrual cyclicity? SUMMARY ANSWER The female reproductive system may be sensitive to PFOA exposure, with longer menstrual cycle length at higher exposure. WHAT IS KNOWN ALREADY PFOS and PFOA are persistent man-made chemicals. Experimental animal studies suggest they are reproductive toxi...

This manuscript discusses sex-related differences in headache prevalence, the symptoms and natural history of migraine, associated disability, and co-morbid disorders. The role of sex hormones is discussed with reference to the effects of hormonal events across the reproductive years and the specific effects of the menstrual cycle on migraine. Differences between the sexes were identified acros...

There are not enough studies about the relationship between menstrual psychosis and schizophrenia exacerbation during the menstrual cycle. In patients diagnosed with schizophrenia, it is important to examine the psychotic symptoms and depression and anxiety symptoms during the menstrual cycle and to adjust the treatment according to these symptoms. If depression and anxiety symptoms are present...

BACKGROUND The transcription factor CCAAT/enhancer-binding protein (C/EBP) beta is a critical mediator of murine endometrial function during embryo implantation. Our objective is to characterize changes in C/EBP beta mRNA abundance and protein localization over the normal human menstrual cycle. METHODS Fifty normally cycling volunteers without reproductive disorders were randomized to undergo...
