was sind östrogen — when to see a doctor?

Estrogens are a group of female sex hormones primarily produced in the ovaries, regulating the menstrual cycle, fertility, and bone health. Men also produce small amounts. You should see a doctor if you experience unexplained cycle irregularities, severe PMS, early menopause symptoms, unusual bleeding, or if a home hormone test shows abnormal results. Important: home estrogen tests are not diagnostic and cannot replace clinical evaluation. The evidence for self-managing estrogen levels based on such tests is weak. Seek medical advice for symptoms like hot flashes, sleep disturbances, mood swings, or loss of libido. A gynecologist or endocrinologist can perform proper testing and interpretation, which is age-dependent and complex. Self-testing may lead to misinterpretation and unnecessary anxiety.
