It’s no coincidence, given all the estrogenic chemicals in our lakes and seas, that there are fewer male fish in the world; in the human world, men produce less than half as many sperm as they did fifty years ago, and women suffer from estrogen-dependent diseases such as endometriosis at a historically high rate. We’re also inundated by stress, another endocrine disruptor. Chronic low-grade anxiety affects the feedback between your brain’s hypothalamus, pituitary gland, and adrenal glands—a configuration known as the HPA-axis, which regulates digestion, immunity, moods, libido, and energy.
