title: Estrogen receptor beta and its selective ligands: an option for treatment of menopausal vasomotor symptoms?
abstract: Abstract In the human female, menopause is the permanent end of fertility, defined as occurring 12 months after the last menstrual period. During peri- and postmenopausal stages, the vast majority of women experience moderate-to-severe vasomotor symptoms, such as hot flashes and night sweats, which interfere with sleep and may be severe enough to affect quality of life. The only treatment approved by national health authorities is hormone therapy with estrogen alone or in combination with a progestagen. However, this therapeutic regimen is associated with severe side effects, such as stimulation of growth of breast cancer or cardiovascular events. Thus, there is a demand for efficient and safe alternative treatments for menopausal complaints. After the discovery of estrogen receptor beta in many organs, and confirmation of its presence in the brain, many researchers raised the question of whether ERβ-specific ligands may be novel therapeutic agents for treatment of menopausal complaints with the desirable effects of estrogen but without increased risk of tumor incidence. This minireview will briefly summarize the relevance of estrogen receptor beta and its specific ligands for the treatment of menopausal symptoms with a focus on vasomotor menopausal symptoms. At present, estrogen receptor beta-selective ligands do not seem to be active in models of prevention or reversal of osteoporosis. However, data from animal experiments suggest that estrogen receptor beta-selective ligands might be safe therapeutics for the treatment of vasomotor menopausal symptoms.
