We examined the effects of exercise intensity and menstrual cycle phase on glucose flux rates during rest and exercise in rested and fed (3-h postabsorptive) women. Eight moderately active, eumenorrheic women were studied under conditions of rest (90 min) and exercise (60 min, leg ergometer cycling at 45 and 65% peak oxygen consumption) during follicular and luteal phases. In both menstrual pha...

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...

This study investigated the changes of prostate specific antigen (PSA) concentrations in serum and saliva of women during the menstrual cycle. Thirty healthy volunteers (age 23-35 yr) were enrolled in the study. During the menstrual cycle, serum and saliva PSA concentrations on days 9 (follicular phase) and 14 (mid-cycle) were significantly higher than on days 4 (early follicular phase) and 21 ...

BACKGROUND Many asthmatic women complain of symptom exacerbations in particular periods, i.e. during pregnancy and menstrual cycles (perimenstrual asthma: PMA)". The goal of this study was to study the effect of the luteal and follicular phases of the menstrual cycle on bronchial reactivity (BR) in a group of asthmatic women. METHODS For this purpose, 36 pre-menopausal women were enrolled and...

This article aims to throw light on the controversial topic of whether women have a 'heat' period within their menstrual cycle. The majority of publications in this field report, in addition to a periovulatory peak, no changes at all or even rises in male- and female-initiated sexual activity, woman's sexual desire, autosexual activity and sexual arousability, and interpersonal sexual activitie...

The aim of present study was to investigate the occurence of different lymphocyte subsets in the endometrium of endometriosis patients and in healthy women on every day of the menstrual cycle with special emphasis to the proliferative activity of endometrial cells with Ki-S3 antibody. We also conducted immunohistochemical studies of T-lymphocytes, B-lympho-cytes, macrophages, natural-killer-cel...

The menstrual cycle has attracted research interest ever since the 1930s. For many researchers the menstrual cycle is an excellent model of ovarian steroid influence on emotion, behavior, and cognition. Over the past years methodological improvements in menstrual cycle studies have been noted, and this review summarizes the findings of methodologically sound menstrual cycle studies in healthy w...

PURPOSE  The primary objective of this study is to determine how the phases of the menstrual cycle influence the results of polysomnography (PSG). METHODS  Twenty-eight adult subjects who reported regular menstrual periods, last menstrual period (LMP) within 26 days of their PSG, no exogenous hormone use, no history of polycystic ovarian syndrome, and who were scheduled for diagnostic PSG at ...

BACKGROUND We have previously shown that the menstrual cycle has no effect on rectal sensitivity of normal healthy women, despite them having looser stools at the time of menses. Patients with irritable bowel syndrome (IBS) often report significant exacerbation of their IBS symptoms with menses, raising the possibility that IBS patients may respond differently to the menstrual cycle. AIM AND ...

AIM OF THE STUDY This study explored characteristics of the menstrual cycle including duration, prevalence and severity of symptoms and examined the relationship of these characteristics with attitudes toward menstruation. BACKGROUND Conceptualization of menstrual phenomena and attitudes toward menstruation may vary among cultures. While data about menstrual health among American women are wi...
