Research on<unk> es is mostly focused on treatment options. The exact cause and pathogenesis, or causes, of vasomotor symptoms (VMS)—the clinical name for<unk> es—has not yet been fully studied.<unk> es are associated with declining levels of estrogen (estrogen withdrawal) and other hormonal changes. It does not appear that low levels of estrogen are the primary cause of<unk> es, as women who experience<unk> es have around the same plasma estrogen levels as women who do not have them, and prepubertal girls do not have<unk> es despite low estrogen levels. There are indications that<unk> es may be due to a change in the hypothalamus's control of temperature regulation. Transgender men on hormone blockers to halt their female puberty also commonly experience<unk> es, because hormone blockers simulate or induce menopause.
