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...

Objective. This study is performed to obtain objective diagnostic indicators associated with menstrual pain using pulse wave analysis. Methods. Using a pulse diagnostic device, we measured the pulse waves of 541 women aged between 19 and 30 years, placed in either an experimental group with menstrual pain (n = 329) or a control group with little or no menstrual pain (n = 212). Measurements were...

on a positive balance between intestinal absorption and loss from the body. Iron deficiency is a common cause of anaemia (Kilpatrick, 1961) and in women is often associated with high levels of menstrual blood loss (Jacobs and Butler, 1965). When menstrual loss is increased iron balance must be maintained either by a diet with a high iron content or by an increase in the proportion absorbed by t...

This study tested the hypothesis that effects of the menstrual cycle on resting blood pressure carry over to dynamic exercise. Eleven healthy females were studied during the early (EP; low estrogen, low progesterone) and late follicular (LP; high estrogen, low progesterone) menstrual phases. Stroke volume (SV), heart rate (HR), cardiac output (CO), systolic blood pressure (SBP), diastolic blood...

OBJECTIVES To investigate the hormonal contraceptive practices of female university students aged ≤ 25 years, their menstrual bleeding frequency, and interest in contraceptive regimens that reduce menstrual frequency or duration. STUDY DESIGN A 20-item questionnaire was distributed to female students at Griffith University, Gold Coast campus. This included questions relating to: demographics,...

BACKGROUND Copeptin, a surrogate marker for arginin vasopressin production, is evaluated as an osmo-dependent stress and inflammatory biomarker in different diseases. We investigated copeptin during the menstrual cycle and its relationship to sex hormones, markers of subclinical inflammation and estimates of body fluid. METHODS In 15 healthy women with regular menstrual cycles, blood was draw...

Excessive menstrual bleeding—menorrhagia is a common gynecologic disorder affecting women of reproductive age. Subjectively, menorrhagia is defined as a complaint of heavy cyclical menstrual bleeding occurring over several consecutive cycles (Rönnerdag and Odlind, 1999). Objectively, it can be defined as heavy menstrual bleeding lasting for more than 7 days or resulting in the loss of more than...

The objective of this study was to identify the optimal timing of sampling during the menstrual cycle for assessment of interindividual variation in exposure to endogenous sex hormones, including estradiol, progesterone, and the free androgen index. Twenty-four healthy premenopausal women with regular periods were recruited, and alternate day venous blood samples were taken in the morning throu...

BACKGROUND Tubal ligation (TL) is recommended for women who have completed their family planning. The existence of the menstrual disorders following this procedure has been the subject of debate for decades. This study was conducted to identify the relationship between tubal ligation and menstrual disorders. MATERIALS AND METHODS A historical cohort study was carried out on 140 women undergoi...
