1. Water and electrolyte excretion has been measured in both the follicular and luteal phases of the menstrual cycle in eight normal females undergoing a sustained water diuresis. 2. When the subjects were supine, no differences were found in urinary excretion during the follicular and luteal phases. 3. When the subjects were tilted to the upright position, the urine volume, excretion of sodium...

PURPOSE The present study aimed to compare the serum LTG levels during the early-/mid-follicular (low estradiol) and mid-luteal (high estradiol) phases of the physiologic menstrual cycle. METHOD In a cross-sectional study, 20 women with epilepsy were recruited. Participants had been on monotherapy with LTG for at least two months. All the subjects had normal menstrual cycles. Blood samples fo...

The purpose of this study was to determine whether the changes of sex hormone-binding globulin (SHBG) affect the pregnancy outcome in women undergoing controlled ovarian hyperstimulation (COH) for assisted reproduction. Forty-five infertile women who were undergoing pituitary desensitization and COH for in vitro fertilization (IVF) with or without intracytoplasmic sperm injection (ICSI) and 19 ...

It has been demonstrated elsewhere that circulating renin angiotensin system (RAS) components peak when plasma estrogen levels are highest, during the luteal phase of the normal menstrual cycle. This phenomenon has been attributed to "activation" of the RAS. The end-organ vasoconstrictive response to this phenomenon has not been well established. In two related experiments, the RAS was studied ...

OBJECTIVE To investigate whether allopregnanolone, a neuroactive steroid involved in modulating behavioural and neuroendocrine functions, shows episodic secretion in eumenorrheic women, during the follicular and luteal phases of the menstrual cycle, and in women with stress-induced amenorrhea. PATIENTS Six eumenorrheic women and 14 women with hypothalamic amenorrhea were enrolled for the pres...

CONTEXT About 10% of Japanese female athletes are afflicted by menstrually-related edema, mainly in the lower limbs, and, with few studies on this problem, the effect on performance remains unclear. OBJECTIVE To quantitatively evaluate fluid retention in the calf in female students over their menstrual cycle using magnetic resonance imaging (MRI) and to determine the relationship of MRI chang...

BACKGROUND The stem cell marker Octamer-4 (OCT-4) is expressed in human endometrium. Menstrual cycle-dependency of OCT-4 expression has not been investigated to date. METHODS In a prospective, single center cohort study of 98 women undergoing hysteroscopy during the follicular (n = 49) and the luteal (n = 40) phases of the menstrual cycle, we obtained endometrial samples. Specimens were inves...

The effect of the menstrual cycle on oro-cecal transit time (OCTT) has been controversial. Since poor reproducibility of OCTT measurements by lactulose might be responsible for this controversy, we measured OCTT with either milk or a solid test meal during the luteal and follicular phases of the menstrual cycle. Nine healthy young women (21.9 +/- 0.42 years old) with regular menstruation were s...

in this study the reproductive organs of adult and apparently healthy female azarbaijan buffaloes werecollected after slaughter from abattoir. through observation of the ovaries, the luteal and follicular phases ofeach buffalo were specified. a total number of 36 oviducts at follicular phase and 36 oviducts at luteal phasewere collected and 3 tissue samples were taken from 3 regions of infundib...
