The aim of this study was to evaluate whether the differences in plasma 17beta-estradiol concentration in early and late follicular phases of the menstrual cycle can affect the level of endogenous DNA damage in lymphocytes assessed by comet assay, and whether the extent of this damage in the follicular phase is associated with the genotype of catechol-O-methyltransferase (COMT). The level of DN...

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: Food intake fluctuates throughout the menstrual cycle; it is greater during the early follicular and luteal phases than in the late follicular (periovulatory) phase. Ovarian steroids can influence brain areas that process food-related information, but the specific contribution of individual hormones and the importance of the prandial state remain unknown. Objective: The objective wa...

BACKGROUND The menstrual cycle influences pain, with symptoms often increasing during the premenstrual (late-luteal) phase. Deficiencies in endogenous inhibition of afferent nociception at the spinal level might contribute to menstrual phase-related changes in pain. PURPOSE This study assessed whether conditioned pain modulation (CPM) of spinal nociception differs between mid-follicular and l...

Auditory steady-state responses (ASSRs) are widely applied to test brain's ability to follow external stimulation in neuropsychiatric disorders. It is known that ASSRs are related to GABAergic transmission. Female sex steroid homones - both estrogens and progesterone - affect functioning of GABAergic system. However, it is not known how these hormones affect brain's ability to entrain. This stu...

Ovarian stimulation is usually carried out with exogenous gonadotropins to induce multiple follicle development and to mature more oocytes for in vitro Fertilization (IVF) [1]. According to the traditional folliculogenesis, antral follicles in each ovary are recruited from the late luteal phase of the preceding menstrual cycle for the following follicle phase. The dominant follicle is selected ...

BACKGROUND Neuroticism, which is a personality trait characterized by the tendency to experience negative affect, is associated with premenstrual negative emotion changes. The present ERP study intended to investigate how neuroticism and the menstrual cycle influence the evaluation of emotion as a function of the tested levels of ovarian hormones. METHOD Forty-two healthy females with regular...

Objectives: This study aimed to assess how menstrual cycle phase and extended length influence the incidence of injuries in international footballers. Methods: Over a 4-year period, from England footballers at training camps or matches were recorded, alongside self-reported information on characteristics point injury. Injuries eumenorrheic players categorized into early follicular, late luteal ...

Nevo O, Soustiel JF, Thaler I. Cerebral blood flow is increased during controlled ovarian stimulation. Am J Physiol Heart Circ Physiol 294: H3265–H3269, 2007. First published October 26, 2007; doi:10.1152/ajpheart.00633.2007.—Estrogen appears to enhance cerebral blood flow (CBF). An association between CBF and physiologically altered hormonal levels due to menstrual cycle, menopause, or exogeno...
