Women in the menopausal transition may experience vaginal itching due to fluctuations in estrogen levels. As estrogen levels decline in the perimenopause, the vaginal wall becomes thinner and drier, and itching may result.
Some studies have shown a link between psychological stress and vaginal yeast infections. This is likely due to the fact that stress is known to have a negative effect on the immune system and could possibly increase the likelihood of getting a yeast infection in women and men.
