Estrogen plays a crucial role in skin health by maintaining collagen levels, enhancing skin thickness, increasing moisture retention through acid mucopolysaccharides and hyaluronic acid, and supporting wound healing, particularly in postmenopausal women. Both topical and systemic estrogen therapies have been shown to increase skin collagen content, while hormone replacement therapy
This cohort study, conducted within the Women’s Health Initiative, examined the relationship between inflammatory biomarkers, hormone replacement therapy (HRT), and coronary heart disease (CHD) risk in postmenopausal women. Among 304 CHD cases and 304 matched controls, elevated baseline levels of C-reactive protein (CRP) and interleukin-6 (IL-6) were significantly associated with
This observational study explores the relationship between estrogen deficiency and the risk of Alzheimer’s disease (AD) in postmenopausal women, finding that those who used estrogen replacement therapy (ERT) had a lower risk of developing AD, with the protective effect increasing with longer use. While the exact mechanism is unclear, estrogen
This randomized controlled trial from the Women’s Health Initiative examined the effects of combined estrogen and progestin therapy on the incidence of peripheral arterial disease (PAD) in postmenopausal women. The study found no significant reduction in PAD risk among women receiving hormone therapy compared to those on a placebo, suggesting
This review examines the relationship between estrogen replacement therapy (ERT) and migraines in postmenopausal women, highlighting that stable estrogen levels achieved through ERT may help reduce migraine frequency in some individuals while triggering migraines in others. The study emphasizes the need for a personalized approach, as fluctuations in estrogen are
This 1998 meta-analysis evaluated the effects of estrogen therapy on cognitive function and dementia in postmenopausal women, synthesizing data from five observational studies and eight trials. The findings suggest that estrogen may support cognitive function through mechanisms such as promoting cholinergic and serotonergic activity, maintaining neural circuitry, and preventing cerebral
This article examines the role of estrogen in cognitive aging and the potential benefits of hormone therapy (HT) for postmenopausal women. The authors review basic neuroscience findings, clinical studies, and epidemiological data to explore how estrogen influences brain function, including its neuroprotective effects on synaptic plasticity and cognitive processes. While
This 2007 randomized controlled trial evaluated the effects of transdermal testosterone therapy in postmenopausal women diagnosed with hypoactive sexual desire disorder (HSDD). The study found that testosterone therapy significantly improved sexual desire and activity levels compared to placebo, with increases in satisfying sexual episodes and overall sexual function scores. Testosterone
This randomized controlled trial investigated the effects of combined hormone replacement therapy (HRT) on health-related quality of life in postmenopausal women. The study found that, after one year of treatment, HRT significantly improved vasomotor symptoms, sexual functioning, and sleep quality compared to a placebo. Specifically, the incidence of hot flushes
This article revisits the effects of hormone replacement therapy (HRT) on cardiovascular disease, particularly in postmenopausal women. It highlights the Women’s Health Initiative (WHI) study, which initially showed risks such as increased cardiovascular events and cancer, leading to the conclusion that HRT should be avoided. However, further analysis indicated no
