Hi, from Newson Health Balance App...
"There hasn’t been much research on hearing, tinnitus, the menopause and HRT. You have estrogen receptors in the cells in your ear and along the auditory pathway, but it’s still not clear what estrogen, testosterone or progesterone’s exact roles are for hearing. Some studies show that low estrogen levels can impair hearing. Experts have hypothesised that alterations in blood flow to the inner ear tube (the cochlear) and changes to the composition of the blood affect the regulation of the electrochemical impulses generated by the hair cells in the cochlear, which in turn alters the auditory signals."
I get tinnitus when oestrogen levels are fluctuating or too low. I also have very narrow ear canals and struggle with ear pain if oestrogen is too high. Perhaps we are all affected differently, and some not at all.
