Neuroendocrine researchers Rettberg, Yao and Brinton describe estrogen as a master regulator of bioenergetic systems in the female brain and body. Estrogen regulates glucose transport, mitochondrial function and ATP production in the brain
Estrogen signaling in hippocampal and cortical neurons acts on mitochondria to increase glucose use, mitochondrial respiration and production of ATP—the usable energy cells need to work.
Progesterone is active in bone metabolism. Jerilynn Prior’s work describes estradiol (estrogen) and progesterone as partners in bone remodeling: estradiol restrains bone resorption while progesterone promotes osteoblast activity and new bon
Modern kidney research identifies progesterone receptors in kidney tissue and finds that progesterone participates in renal blood flow, filtration, sodium and water handling, and the renin-angiotensin-aldosterone system. A 2025 review concl
In a prospective study of 259 healthy women, high daily perceived stress was associated with 9.5% lower estradiol, 10.4% lower free estradiol, 10.4% lower luteal progesterone, 14.8% lower luteinizing hormone and 2.2 times the odds of not ov
Women experience adverse drug reactions about twice as often as men. Research on sex differences in pharmacokinetics—the way the body absorbs, distributes, metabolizes and eliminates drugs—shows that giving women and men the same dose can p
A pharmacokinetic analysis identified 86 drugs with substantial sex differences. Women given the same dose as men routinely had higher blood concentrations and/or longer elimination times. For drugs with higher pharmacokinetic exposure in w
Human PET-imaging research has documented declines in cerebral glucose metabolism associated with the menopause transition.
Estrogen receptors and estrogen-dependent signaling are involved in multiple body systems, including the brain, cardiovascular system, bone, muscle, metabolism, thermoregulation, and other tissues.
Perimenopause can involve irregular ovulation, fluctuating estrogen levels, and reduced progesterone production. Estrogen does not necessarily fall in a smooth, straight line.
