Examples include oophorectomy, oral estrogen therapy, adrenal insufficiency, corticosteroid adrenal suppression, and hypopituitarism (19–21). Aging afflicts sexual endocrinology in other ways. Engagement in a secure and attractive relationship, a safe place, good health, and no drugs remain as core issues. Declining estrogens.
