Endometriosis, one of the most common benign gynecological diseases, affects millions of women of childbearing age. Endometriosis-associated pain is a major cause of disability and compromised quality of life in women. Neuropathic mechanisms are believed to play an important role. An imbalanced sympathetic and sensory innervation (reduced sympathetic innervation, with unchanged or increased sen...

Epithelial ovarian cancer (EOC) accounts for about 90% of malignant ovarian tumors, and estrogen is often implicated in disease progression. We therefore compared the potential for gating of estrogen action via pre-receptor metabolism in normal human ovarian surface epithelium (OSE), EOC and selected EOC cell lines (SKOV3 and PEO1). Steroid sulphatase (STS), estrogen sulfotransferase (EST), 17β...

OBJECTIVE To review the role of circulating C(19) steroids as precursors of estrogens in postmenopausal women. DESIGN Review of current published literature. RESULT(S) In postmenopausal women as in men, estradiol no longer functions as a circulating hormone, because it ceases to be formed by the ovaries at the time of menopause. Estradiol continues to be formed in a number of extragonadal s...

OBJECTIVE This study aims to determine the emotional and physical impact of vaginal atrophy on North American postmenopausal women and their male partners. METHODS A weighted sample of 1,000 married or cohabiting North American postmenopausal women aged 55 to 65 years with vaginal discomfort and 1,000 male partners of postmenopausal women aged 55 to 65 years who experienced vaginal discomfort...

Estrogen acts in the hypothalamic ventromedial nucleus (VMH) to promote female sexual behavior. One potential mechanism through which estrogen may facilitate this behavior is by reconfiguring synaptic connections within the VMH. Estrogen treatment increases the number of synapses and dendritic spines in the VMH, but how this remodeling occurs within the context of the local, behaviorally releva...

BACKGROUND Effects of estrogen on bone metabolism and its protective role on prevention of osteoporosis are well documented. However, the efficacy of estrogen treatment on bone healing is not well investigated. The drug can be delivered both systemically or locally to the bone with differences in concentrations and side effects. The aim of this study was to investigate the effect of local and s...

Estrogens are the key hormones regulating the development and function of reproductive organs in all vertebrates. Recent evidence indicates that estrogens play important roles in the immune system, cancer development, and other critical biological processes related to human well-being. Obviously, the gonads (ovary and testis) are the primary sites of estrogen synthesis, but estrogens synthesize...

More than two-thirds of breast cancers occur in post-menopausal women, and depend on the estrogens for their proliferation and survival. For the treatment of estrogen-dependent breast cancers, two major treatment options are now available. One is selective estrogen receptor modulator (SERM) such as Tamoxifen and another is aromatase inhibitor such as Anastrozole, Letrozole and Exemestane, which...

Abstract Estrogen, the major female sex hormone has been linked with immune response disparity between males and females. However, exact mechanism by which estrogen impacts our ability to fight viral infection development of immunologic memory remains unknown. CD8 T cells represent primary protective against viruses cancer. Here we aim understand how cell mediated antiviral is regulated estroge...
