objectives in this study the association of phenotypes and activity of butyrylcholinesterase (buche) with serum level of lipid-lipoprotein and apolipoproteins during various phases of menstrual-cycle was determined. methods the study population consisted of 22 healthy women aged 19–25 years with regular menstrual cycles, 26–30 days in length. the serum levels of lipids, apolipoproteins, and buc...

BACKGROUND Studies suggested that microRNAs influence cellular activities in the uterus including cell differentiation and embryo implantation. In assisted reproduction cycles, luteal phase support, given to improve endometrial characteristics and to facilitate the implantation process, has been a standard practice. The effect of different types of luteal phase support using steroid hormones in...

Background: Mammographic breast density may be greater in the luteal phase (days 15-30) than the follicular phase (days 1-14) of the menstrual cycle; this may have implications for when mammography screening should occur. Objective: Examine whether percent breast density, breast area, or dense area differ by menstrual phase. Methods: We identified 204 premenopausal women with regular periods wh...

Several studies have suggested that the menstrual cycle has the impact on sedation. No previous study has evaluated the effects of the menstrual cycle on sedation level and propofol requirement with preoperative intravenous dexmedetomidine. Sixty-four adult fertile women receiving general anesthesia for elective gynecologic surgery were included in the study. Patients were classified into four ...

Recent findings In random-start protocols, the number of total and mature oocytes retrieved, oocyte maturity rate, mature oocyte yield and fertilization rates are similar to those in conventional (early follicular phase start) protocols. Starting ovarian stimulation in the late follicular or luteal phase did not show any superiority against the other. The presence of corpus luteum or luteal pha...

It is well established that women experience food craving for particular foods and gain weight in relation to phases of menstrual cycle. In this study, the preference for different concentrations of salt sprayed on bland popcorn was assessed in 55 healthy women (age 18 to 22 yrs). Salt solutions of 0, 1, 2, 3 and +3 molar strength were used. Samples of sprayed popcorn were consumed in random or...

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...

The majority of women of reproductive age experience a regular recurrence of various symptoms in the premenstrual phase. The etiopathogenesis of premenstrual symptomatology, however, remains inconclusive. The present study was proposed to evaluate whether the activity of the autonomic nervous system (ANS), which largely contributes to the relative stability of a human's internal environment, is...

Blood pressure decreases during early pregnancy in association with a decrease in peripheral vascular resistance and increases in renal plasma flow and glomerular filtration rate. These early changes suggest a potential association with corpora lutea function. To determine whether peripheral vasodilation occurs following ovulation, we studied 16 healthy women in the midfollicular and midluteal ...

BACKGROUND The blood supply to the uterus is provided by the uterine and ovarian arteries, which form anastomoses. Yet the flow direction through this anastomoses and the primary source of blood supply to the tubes and uterine cornua remains unknown. To clarify this issue, we studied the spatial propagation of temperature changes following cooling of the upper vaginal area. METHODS A thermoca...
