Importance: Premenstrual syndrome (PMS) is characterized by physical and psychological symptoms in the luteal phase. Leptin can influence PMS as it acts on the hypothalamic-pituitary-gonadal axis. Objective: The aim of this study was to evaluate data in the literature about the profile of plasma leptin in women with PMS. Evidence Acquisition: We performed a search of databases using both descriptors. Three studies were identified. They included 181 participants...

BACKGROUND: Difficulties in regulating emotions are linked to the core symptoms of premenstrual dysphoric disorder (PMDD). We therefore investigated the neural substrates of emotion-regulation problems in women with PMDD. METHODS: On the basis of self-evaluations over 2 months on the Daily Record of Severity of Problems, eligible participants were assigned to two groups: PMDD and control (18 per group). Functional magnetic resonance imaging (fMRI) and a well-validated task were used to assess brain function during emotion regulation...

In mammography, breast compression is necessary and an important factor influencing image quality. The purpose of this study was to determine the influence of the menstrual cycle on compression-induced pain during mammography and to evaluate the association between the thickness and volume of the mammary gland and pain. We examined basal body temperature and categorized the menstrual cycle into five phases. We executed breast compression in the craniocaudal view using a customized compression plate, to which we introduced an opening...

Widespread application of the plasma aldosterone/renin ratio (ARR) as a screening test has led to the recognition that primary aldosteronism (PA) is the most common specifically treatable and potentially curable form of hypertension, accounting for 5-10% of patients. Maximal detection requires accurate diagnostic approaches and awareness and control of factors that confound results, including most antihypertensives, posture, time of day, dietary salt, and plasma potassium. Recent studies have revealed potential for false positives in patients on beta-adrenoceptor blockers, and, when direct renin concentration (but not plasma renin activity) is used to measure renin, in women during the luteal phase of the menstrual cycle or receiving estrogen-containing contraceptives or hormonal replacement therapy...

According to the ovulatory shift hypothesis, women's mate preferences for male morphology indicative of competitive ability, social dominance, and/or underlying health are strongest at the peri-ovulatory phase of the menstrual cycle. However, recent meta-analyses are divided on the robustness of such effects and the validity of the often-used indirect estimates of fertility and ovulation has been called into question in methodological studies. In the current study, we test whether women's preferences for men's beardedness, a cue of male sexual maturity, androgenic development and social dominance, are stronger at the peri-ovulatory phase of the menstrual cycle compared to during the early follicular or the luteal phase...

STUDY QUESTION: Do both ulipristal acetate (UPA) and mifepristone inhibit embryo-endometrial attachment at concentrations corresponding to the emergency contraception (EC) dose? SUMMARY ANSWER: Both UPA and mifepristone at concentrations corresponding to the EC dose do not have an inhibitory effect on embryo implantation, although mifepristone at a higher concentration appeared to have such an effect. WHAT IS KNOWN ALREADY: Levonorgestrel is commonly used for EC, but it only acts through inhibition of ovulation...

OBJECTIVE: The aim of the study was to test the hypothesis that the development of luteal phase dominant follicles (LPDFs) as women age is associated with abnormal luteal function. METHODS: Luteal and antral follicle diameter were quantified in ovulatory women of midreproductive age (MRA; 18-35 y; n = 9) and advanced reproductive age (ARA; 45-55 y; n = 16) every 1 to 3 days during one complete interovulatory interval. Blood was drawn at each visit and assayed for progesterone, estradiol, inhibin A, follicle-stimulating hormone, and luteinizing hormone...

Little is known about the regulation of temporal variations of progesterone over the 24-hr span in young cycling women as well as in postmenopausal women. The purpose of the present study was to investigate the relationships between diurnal variations of progesterone and diurnal variations of hormones of the gonadotropic and corticotropic axes, and to provide further information on the source of progesterone secretion under physiological conditions. Twenty-four-hour hormonal profiles were explored under well-controlled laboratory conditions in 10 healthy women (21-36 yr old) with normal ovulatory cycles during early-mid follicular and late luteal phases, and in 8 healthy postmenopausal women (48-74 yr old)...

OBJECTIVE: To assess ultrasound and haematological changes in ovarian hyperstimulation syndrome (OHSS) during the early luteal phase in women at high risk for developing OHSS. METHODS: This is a retrospective cohort study of 319 women undergoing in-vitro fertilisation (IVF), at high risk for OHSS following human chorionic gonadotrophin (hCG) triggering of final oocyte maturation. Patients were treated with GnRH agonist or antagonist protocol and were monitored for 5 days post oocyte retrieval...

Final oocyte maturation using gonadotrophin-releasing hormone agonist (GnRHa) is increasingly common as it almost eliminates the risk of developing ovarian hyperstimulation syndrome (OHSS) in high-responder patients. The first studies using this approach showed a poor reproductive outcome when only vaginal progesterone was used as luteal phase support, due to the luteolysis that will develop as a result of LH withdrawal. Timely luteal administration of human chorionic gonadotrophin (HCG) will counterbalance the low LH concentrations and therefore maintain progesterone production from the corpora lutea, however, some patients with a high number of follicles will develop OHSS using this approach...

Relaxin is increasingly being recognized as a potent vasodilatory and anti-fibrotic hormone. Given that relaxin is present in the circulation during luteal phase of the menstrual cycle and during pregnancy, when arterial pressure is lowest in women, relaxin may contribute to the relative cardiovascular protection observed in premenopausal women as compared to age-matched men and post-menopausal women. In the present study, we investigated the contribution of relaxin to the normal regulation of arterial pressure in adult female and male mice and during pregnancy...

BACKGROUND: Despite advances in ART, implantation and pregnancy rates per embryo transfer still remain low. IVF laboratories strive to ensure that the process of handling gametes in vitro closely mimics the in vivo environment. However, there remains a lack of knowledge regarding the in vivo regulation and dynamic variation in biophysical parameters such as oxygen concentration, pH and temperature within the reproductive tract. OBJECTIVE AND RATIONALE: To undertake a systematic review of the current understanding of the physico-chemical parameters of oxygen tension (pO2), pH and temperature within the female reproductive tract, and their potential implications in clinical and pathological processes related to fertility and those pertaining to limited reproductive capacity...

PMDD (premenstrual dysphoric disorder) afflicts 3-5% of women of childbearing age, and is characterized by recurrent negative mood symptoms, e.g. irritability, depression, anxiety and emotional lability during the luteal phase of the menstrual cycle. The etiology of PMDD is unknown, but a temporal association with circulating ovarian steroids, in particular progesterone and its metabolite allopregnanolone, during the luteal phase has been established. Allopregnanolone is a positive modulator of the GABAA receptor: it is sedative in high concentrations, but may precipitate paradoxical adverse effects on mood at levels corresponding to luteal phase concentrations in susceptible women...

Breast pain (mastalgia) often precedes menstrual period, which is of mild to moderate severity. This study was performed to determine the effectiveness of chamomile on pain control of cyclic mastalgia. This double-blind randomised controlled clinical trial was conducted on 60 patients with mastalgia referred to the breast clinic of an academic hospital, Mashhad University of Medical Sciences. The patients were randomly allocated into two groups: chamomile (n = 30) and placebo (n = 30). Primary outcomes were: (1) assessment of the visual analogue scale (VAS) and (2) assessment of the breast pain chart (BPC) 8 weeks after initial intervention...

Hyperactivity of the hypothalamic-pituitary-adrenal (HPA) axis may play a role in the pathogenesis of comorbidities encountered in obesity, including the relative hypogonadotropic hypogonadism that we and others have observed. We sought to examine serum cortisol profiles throughout the day and evening in a sample of normal weight women and women with obesity. In this cross-sectional study, regularly cycling obese (n = 12) and normal weight (n = 10) women were recruited. Mean serum cortisol was measured by frequent blood sampling for 16 h (8am-midnight) in the luteal phase of the menstrual cycle...
