Hormones regulate all our bodily functions. As we age, hormone levels can decrease or fall out of balance. For men, plummeting testosterone levels can result in low libido and erectile dysfunction. For women, low estrogen can lead to hot flashes, low libido, and vaginal dryness. For both men and women, shifting hormonal levels can dramatically decrease their quality of life, causing sleeplessness, loss of energy, weight gain and other concerns. BHRT can help to ease symptoms by bringing hormones back into balance.
