premenstrual syndromes (pms) are a group of menstrually related, chronic and cyclical disorders characterized by emotional, behavioral, and physical symptoms in the second half (luteal phase) of the menstrual cycle. several line of evidence point to a significant role of the serotonergic system in the course of the luteal phase in women with pms/ premenstrual dysphoric disorder. it has been rep...

STUDY QUESTION Can the luteal phase support be improved in terms of efficacy, hormonal profiles and convenience as compared with today's standard care? SUMMARY ANSWER Daily low-dose rhCG supplementation in GnRHa triggered IVF cycles can replace the traditional used luteal phase support with exogenous progesterone. WHAT IS KNOWN ALREADY A bolus of hCG for final maturation of follicles in con...

BACKGROUND Premenstrual syndrome (PMS) is a common finding in luteal phase of menstrual cycle resulting in several changes in woman life including pain sensation. OBJECTIVES This study evaluated the alterations of postoperative pain sensation in those with and without a history of PMS. PATIENTS AND METHODS A total of 140 women in in postoperative period were assigned to four groups regardin...

Previous studies have indicated phase-related differences in HPA activity and amygdala responsiveness in women, such that the response to negative emotional images is reduced during high-estrogen phases of the menstrual cycle. Other research has indicated an opposite effect of exogenous progesterone, increasing amygdala activity at some doses. However, no study to date has assessed the response...

Serum Calcium (Ca), Magnesium (Mg) and Inorganic phosphorous (Pi) were investigated serially during menstrual, follicular, ovulatory and luteal phases of menstrual cycle in 25 healthy medical student volunteers. The result shows significant cyclic variations within physiological limits in all parameters. Ca level was highest during ovulation (P < 0.001) and lowest during luteal phase (P < 0.001...

BACKGROUND Controlled ovarian stimulation combined with intra uterine insemination (IUI) is a convenient treatment of infertility with a success rate of 11%. The clinical observation and pattern of progesterone secretion in this method is suggestive of luteal phase defect and postulated as an implicating factor of treatment failure. OBJECTIVE To investigate the efficacy of luteal phase suppor...

Gender differences in the incidence of many cardiovascular diseases may be due to the effects of sex hormones. Both alpha(1)- and alpha(2)-adrenergic receptors produce vasoconstriction in peripheral blood vessels and have demonstrated gender effects in previous studies. In addition, race has been shown to influence the effects of some alpha-adrenergic stimuli. We therefore sought to determine t...

CONTEXT Over the years, different hypotheses involving the ovarian steroid hormones have been proposed to explain the luteal phase occurrence of severe premenstrual syndrome symptoms. Although it had been strongly suspected that differences in the concentrations of the ovarian steroids may underlie the mood and psychological imbalance of this disorder, the evidence for this hypothesis has been ...
