Hi Katherine,
This is from Women's Internation Pharmacy but there are a lot of other websites regarding the link between tinnitus and hormones:
The onset of tinnitus in women seems to be particularly related to periods of hormone variability. It can be triggered by PMS, perimenopause, menopause and pregnancy. Menopausal symptoms such as sweating, hot flashes and mood changes may correlate with tinnitus.
One 2017 study by Dr. Sharon Curhan reports that low estrogen levels can impair hearing, likely through alterations in blood flow to the cochlea, in both animals and humans. Another study from 2002 found that post-menopausal women with less estradiol (a form of estrogen) were more likely to have hearing loss than those with more.
