Female Reproductive Hormones Alter Sleep Architecture in Ovariectomized Rats

Cognitive Impairments of Sleep-Deprived Ovariectomized (OVX) Female Rats by Voluntary Exercise

Introduction: Previous studies demonstrated that forced and voluntary exercise had ameliorative effects on behavioral tasks followed by Sleep Deprivation (SD) in intact female rats. The main goal of this research was evaluating the impact of voluntary exercise on cognitive functions while SD and ovariectomization is induced in female wistar rats. Methods: The rats were anesthesized combining d...

Reproductive hormones and sleep apnea

OBJECTIVES : Decreased libido and a decline in morning serum testosterone levels were reported in men with obstructive sleep apnea (OSA). Our study aimed to evaluate the pituitary-gonadal axis in middle age men with OSA before and after treatment with nasal continuous positive airway pressure (CPAP). MATERIAL AND METHODS : Measurement of the nocturnal serum luteinizing hormone (LH) and testoste...

Effect of food restriction on reproductive-related genes and reproductive hormones in adult female rats.

OBJECTIVES A number of factors involved in the control of energy balance and metabolism act as modulators of gonadal axis. Ghrelin, a peptide secreted from the stomach and hypothalamus, has emerged as an orexigenic food intake controlling signal acting upon hypothalamus. Recently, the potential reproductive role of ghrelin has received great attention. This study was designed to investigate the...

Sulpiride-Induced Hyperprolactinemia in Mature Female Rats: Evidence for Alterations in The Reproductive System, Pituitary and Ovarian Hormones

Estrogen and tamoxifen modulate cerebrovascular tone in ovariectomized female rats.

Postmenopausal estrogen deficiency increases the incidence of cerebrovascular disease. However, hormone replacement therapy is associated with an increased cardiovascular risk. Tamoxifen is a selective estrogen receptor modulator with estrogenic effects on cardiovascular risk factors, but its long-term impacts on cerebral vasculature are unknown. We hypothesized that chronic 17beta-estradiol or...
