A new coronavirus illness (COVID-19) pandemic is an important public health problem across the globe. The COVID-19 has sparked widespread media and blog debate about women undergoing alterations in their menstrual cycle, including enhanced dysmenorrhea, bleeding, increased frequency, intensity, pattern, volume, premenstrual syndrome (PMS). Premenstrual affects overall well-being of reproductive...

Women's basal body temperature (BBT) shows a periodic pattern that associates with menstrual cycle. Although this fact suggests a possibility that daily BBT time series can be useful for estimating the underlying phase state as well as for predicting the length of current menstrual cycle, little attention has been paid to model BBT time series. In this study, we propose a state-space model that...

Previous studies have shown that progesterone concentrations in serum and nipple aspirate fluid (NAF) are significantly correlated in premenopausal women, but estradiol concentrations are not. We therefore sought to ascertain the patterns of both steroids in NAF throughout the menstrual cycle and in postmenopausal women. Simultaneous samples of blood and NAF were obtained from 40 premenopausal ...

INTRODUCTION Endometriosis is defined as overgrowth of endometrial tissue outside the uterine cavity. Endometriosis may be asymptomatic or associated with dysmenorrheal symptoms, dyspareunia, pelvic pain, abnormal uterine bleeding and infertility. The aim of this study was to explore the risk factors related to endometriosis among infertile Iranian women. MATERIAL AND METHODS In this case con...

BACKGROUND The objective of this study was to identify baseline predictors of live birth in anovulatory patients undergoing ovulation induction, and based on these predictors, develop nomograms for estimation of the probability of live birth in a single cycle. METHODS Univariate and multivariate logistic regression were used for retrospective analysis of clinical, sonographic and endocrinolog...

OBJECTIVES We investigated whether open-heart surgery with the use of extracorporeal circulation has an impact on menstrual bleeding. METHODS The menstrual bleeding pattern was registered in fertile women undergoing open-heart surgery in 2010-12. Haematocrit and 24-h postoperative bleeding were compared with those of men undergoing cardiac surgery. RESULTS Women (n = 22), with mean age of 3...

In order to throw further light on the role of androgens in the aetiology of the polycystic ovary syndrome (PCO) we have examined the effect of artificially increasing serum testosterone levels on menstrual function in a group of ovulating women. Six women were studied who had either severe premenstrual syndrome or loss of libido for which they were treated with 100 mg testosterone by s.c. impl...

Men typically outperform women in spatial navigation tasks, while the advantage of women in verbal fluency is more controversial. Sex differences in cognitive abilities have been related to sex-specific cognitive strategies on the one hand and sex hormone influences on the other hand. However, sex hormone and menstrual cycle influences on cognitive strategies have not been previously investigat...

Factors associated with the menstrual cycle, such as the endogenous hormones estrogen and progesterone, have dramatic effects on cardiovascular regulation. It is unknown how this affects postexercise hemodynamics. Therefore, we examined the effects of the menstrual cycle and sex on postexercise hemodynamics. We studied 14 normally menstruating women [24.0 (4.2) yr; SD] and 14 men [22.5 (3.5) yr...
