Women like Kirchoff have been frightened away from hormone therapy ever since a large clinical trial called the Women's Health Initiative found seven years ago that the treatments raised the risk of breast cancer, heart disease, and strokes. Prescriptions for estrogen and progesterone—the typical combination regimen that protects against uterine cancer, which can result from taking estrogen alone—quickly dropped (breast cancer rates did too, partly because of this). Today, doctors no longer prescribe hormones as they once did to prevent osteoporosis, clogged arteries, and dementia. Many experts, however, contend that the pendulum has swung too far, leaving women without any effective remedy for severe menopausal symptoms. The WHI study, designed to test whether long-term use of hormone therapy could prevent age-related illnesses, "was never meant to test the effectiveness of hormones for symptoms," says Nanette Santoro, director of Montefiore Medical Center's Institute for Reproductive Medicine and Health. The average age of the participants was 63, more than a decade beyond the average age of menopause (and well past the worst of its annoyances).
