Influence of partial sleep deprivation on the secretion of thyrotropin, thyroid hormones, growth hormone, prolactin, luteinizing hormone, follicle stimulating hormone, and estradiol in healthy young women

Rotating Shift Work and Menstrual Cycle Characteristics

“…26 However, smaller studies have suggested an inverse association between exogenously-administered melatonin and estrogen levels. 29 Sleep appears to inhibit pituitary luteinizing hormone (LH) secretion 30,31 ; therefore, it is possible that altered sleep-wake patterns, as seen in shift workers who work rotating or night shifts, could modify LH secretion and thus change the regularity or length of the menstrual cycle. It is a limitation of our study that we did not collect information on sleep behaviors.…”

Identifying target regions for vigilance improvement under hormone replacement therapy in postmenopausal syndrome patients by means of electroencephalographic tomography (LORETA)

“…This suggests that the vigilance-promoting effect of HRT and specifically of the present estrogen-progestogen combination is not merely a consequence of improved sleep, but a genuine drug effect. In this context, it is of interest that our own studies on circadian rhythms with hourly sampling of hormones throughout 3 days and nights showed that sex hormone levels are high during the day and low during the night (Baumgartner et al 1993).…”

Sleep, Circadian Rhythms, and Fertility

“…However, a causal relationship cannot be established and a study of sleep deprivation in the second half of the night did not result in FSH changes in women during the early follicular stage of the menstrual cycle [14]. The same investigation demonstrated that estrogen increased in response to partial sleep loss [14]. However, in a subsequent study, absolute sleep duration was not related to estradiol levels although greater variation in sleep duration was significantly correlated [73].…”

“…A positive association between FSH and sleep duration was found in a study of 160 normally cycling, reproductive age women and persisted after adjusting for age and body mass index [118]. However, a causal relationship cannot be established and a study of sleep deprivation in the second half of the night did not result in FSH changes in women during the early follicular stage of the menstrual cycle [14]. The same investigation demonstrated that estrogen increased in response to partial sleep loss [14].…”
