BACKGROUND In low-income settings, many women and girls face activity restrictions during menses, owing to lack of affordable menstrual products. The menstrual cup (MC) is a nonabsorbent reusable cup that collects menstrual blood. We assessed the acceptability and performance of the MPower® MC compared to pads or tampons among women in a low-resource setting. METHODS We conducted a randomized...

This study aimed to investigate the prevalence of dysmenorrhea in a prospective approach. Menstruation-related diary data were obtained from 2640 female college students in North Sichuan Medical College; dysmenorrhea and related factors were analyzed. Dysmenorrhea occurred in 56.4% of students; 6.5% of dysmenorrheal students suffered from “hard to bear” (unbearable) menstrual pain, and 6.5% had...

Menstrual blood loss was measured in 80 apparently healthy women aged 15-44 years. The study showed a median menstrual blood loss of 37.1 ml per period and the range was from 5.4-169.0 ml. With an average menstrual cycle of 29 days and a mean hemoglobin content of 12.8 g/dl the average iron loss was estimated to be about 0.55 mg/day. The simultaneous effects of menstrual iron loss and dietary i...

The aim of this study was (a) to show that different measures of spatial cognition are modulated by the menstrual cycle and (b) to analyze which steroid is responsible for these cognitive alterations. The authors collected blood samples in 3-day intervals over 6 weeks from 12 young women with a regular menstrual cycle to analyze concentrations of estradiol, progesterone, testosterone, luteinizi...

INTRODUCTION Hormonal fluctuations may influence fibrin structure. During the menstrual cycle, plasma fibrinogen levels change, mainly due to the variations of estrogen. Throughout the menstrual cycle estrogen levels peak twice, first during the mid-follicular phase and then a lower second peak during the luteal phase. MATERIALS AND METHODS In order to investigate the possible changes in the ...

Background: In recent years, numerous regulators of gonadal function have been studied. Adenosine deaminase(ADA) is widely distributed throughout human tissues and may contribute in the regulation of menstrual cycle. The purpose of this study was to determine the plasma activities of total adenosine deaminase (ADAT), and its isoenzymes, ADA1 and ADA2, and ADA1/ADA2 ratio during the menses, foll...

Objectives: To evaluate the efficacy and safety of an intrauterine system releasing 20μg levonorgestrel per 24 hours in the longterm treatment of heavy menstrual blood loss in women unrelated to intrauterine pathology. Methods: Sixty parous women aged 35-48 years with recurrent menorrhagia participated in this study. Women were followed-up for at least 12 months (12-16 months). The effect on me...

BACKGROUND Menstrual blood loss (MBL) has been shown to be an important determinant in iron status, work performance and well-being. Several methods have been developed to estimate MBL, the standard quantitative method however has limited application in clinical practice as it is expensive and requires women to collect, store and submit their sanitary products for analysis. We therefore aimed t...

We investigated the cardiovascular responses to acute hypercapnia during the menstrual cycle. Eleven female subjects with regular menstrual cycles performed hypercapnic rebreathing tests during the follicular and luteal phases of their menstrual cycles. Ventilatory and cardiovascular variables were recorded breath by breath. Serum progesterone and estradiol were measured on each occasion. Serum...

Gas transfer in the female lung varies over the menstrual cycle in parallel with the cyclic angiogenesis that occurs in the uterine endometrium. Given that vessels form and regress in the uterus under the control of hormones, angiogenic factors, and proangiogenic circulating bone marrow-derived progenitor cells, we tested the possibility that variation in pulmonary gas transfer over the menstru...
