OBJECTIVES (1) To describe the progesterone profiles following pituitary down regulation in stimulated IVF cycles with the use of GnRH-a (2) To assess the impact of progesterone supplement and pregnancy on the subsequent luteal phase. STUDY DESIGN A prospective observational study performed in a specialist infertility clinic based at a tertiary centre in the north of England. Subjects were di...

OBJECTIVES A marked increased in food intake in the late-luteal phase is a characteristic symptom of premenstrual dysphoric disorder (PMDD). The aim of the study was to evaluate the leptin level, caloric intake, and eating behaviors of women with PMDD across the menstrual cycle among normal-weight and overweight subjects, respectively. METHODS A total of 62 women with PMDD and 69 controls wer...

PURPOSE To identify molecular alterations potentially involved in predisposition to adnexal serous carcinoma (SerCa) in the nonmalignant fallopian tube epithelium (FTE) of BRCA1/2 mutation carriers, given recent evidence implicating the distal FTE as a common source for SerCa. EXPERIMENTAL DESIGN We obtained and compared gene expression profiles of laser capture microdissected nonmalignant di...

OBJECTIVE: To test hypotheses concerning patterns of caffeine consumption as a function of menstrual cycle phase in women with premenstrual syndrome (PMS), as compared with controls. METHODS: Daily symptom ratings were obtained online for two consecutive menstrual cycles. Women displaying a 30% increase in PMS symptoms during the luteal phase in both cycles were assigned to the PMS group. Parti...

Evaporation by sweating is the most effective way to remove heat from the body. Sweat rates increase under both local and whole-body heat stress. Men and women differ in how they respond to heat, because sexual steroids alter resting body core temperature and the threshold for sweating and skin blood flow (SBF) during heating. The purpose of the present study was to compare local sweat rates an...

After ovulation, non-pregnant female giant pandas experience pseudopregnancy. During pseudopregnancy, non-pregnant females exhibit physiological and behavioral changes similar to pregnancy. Monitoring hormonal patterns that are usually different in pregnant mammals are not effective at determining pregnancy status in many animals that undergo pseudopregnancy, including the giant panda. Therefor...

BACKGROUND Previous studies of the relationship between the menstrual phases and smoking behavior have been problematic, so the association of menstrual phases with smoking behavior and correlations among smoking, psychological and physical conditions in each phase of the menstrual cycle are unclear. METHODS To accurately examine the association between menstrual phases and the amount of smok...

INTRODUCTION Variations in inflammatory markers have been reported in adult women during the luteal phase, but whether these findings are observed during adolescence is unknown. We postulate that higher ultrasensitive C-reactive protein (usCRP) and lower 2-hydroxyestrone (2OHE) levels, an estrogen metabolite with cardioprotective actions, are present during the luteal phase in young women. AI...

An association between serum carotenoid concentrations and risk for certain cancers has been observed in epidemiological studies. Determinants of serum carotenoid concentrations are known to include dietary intake, plasma lipid concentrations, and body mass. Menstrual cycle phase, which has not been adequately addressed in previous studies, has been suggested to be a possible additional factor ...

OBJECTIVE The purpose of the present study was to investigate autonomic tone during the follicular and luteal phases of the menstrual cycle using heart rate variability (HRV) and heart rate recovery (HRR) in healthy women. SUBJECTS AND METHODS Thirty women aged 22-37 years with regular menstrual cycles were included in the study. The HRV and HRR were measured at the follicular and luteal phas...
