Since menopause is due to the depletion of ovarian follicles/oocytes and severely reduced functioning of the ovaries, it is associated with lower levels of reproductive hormones, especially estrogen. Low estrogen can result in vasomotor instability (such as hot flushes and night sweats), psychological changes (such as mood swings, depression, and difficulty concentrating), insomnia, genital tract atrophy (such as vaginal dryness, painful intercourse, and urinary incontinence), skin changes (such as thinning and decreased elasticity).Lower androgen levels (male hormones) can contribute to the loss of sex drive.
