Relapse to maladaptive eating habits during dieting is often provoked by stress and there is evidence for a role of ovarian hormones in stress responses and feeding. We studied the role of these hormones in stress-induced reinstatement of food seeking and medial prefrontal cortex (mPFC) neuronal activation in c-fos-GFP transgenic female rats, which express GFP in strongly activated neurons. Foo...
In female pigs, undernutrition may influence growth of antral follicles from various size classes, decrease ovulation rate, delay puberty and return to oestrus after weaning. It could also affect the oocyte maturation and hence the number of viable embryos per litter. Inhibition of the gonadotrophin release due to undernutrition is presumably involved in these phenomena. Presence of receptors, ...
BACKGROUND Although 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD) has been associated with alterations in ovarian function and hormones in animals, it has not been studied in humans. On 10 July 1976, an explosion exposed residents of Seveso, Italy, to the highest levels of TCDD in a population. Twenty years later, we initiated the Seveso Women's Health Study to study reproductive health. OBJECTI...
There is a strong association between nutrition and reproduction. Chronic dietary energy deficits as well as energy surpluses can impair reproductive capacity. Metabolic status impacts reproductive function at systemic level, modulating the hypothalamic GnRH neuronal network and/or the pituitary gonadotropin secretion through several hormones and neuropeptides, and at the ovarian level, acting ...
Despite widespread belief that moods are affected by the menstrual cycle, researchers on emotion and reward have not paid much attention to the menstrual cycle until recently. However, recent research has revealed different reactions to emotional stimuli and to rewarding stimuli across the different phases of the menstrual cycle. The current paper reviews the emerging literature on how ovarian ...
Background and purpose: Methamphetamine (METH) is one of the most powerful drugs that leads to many cognitive and behavioral side effects such as anxiety. On the other hand, studies have shown that ovarian hormones such as estrogen and progesterone have neuroprotective effects on a wide range of cognitive and behavioral disorders. The aim of this study was to investigate the role of estrogen an...
Menopause is a physiological process related to the increasing insufficiency of the hypothalamic-hypophyseal-ovarian axis. The pool of ovarian follicles capable of synthesizing female sex hormones becomes gradually depleted. In response to the sequence of endocrine changes of premenopause, perimenopause, and postmenopause, systemic somatic and emotional disturbances appear. Skin is the target o...
