There are two main reasons for female hirsutism: one is excessive testosterone secretion in the body, or although androgen secretion in the body is not much, the sensitivity of hair follicle layer to androgen increases, causing hirsutism. Many people think that women do not secrete androgens, but this is actually a misunderstanding. Normal women also secrete a small amount of androgen, 50% of which comes from follicles and adrenal cortex. Female hirsutism can be seen in several symptoms: First, congenital adrenal hyperplasia. Mainly congenital enzyme defects. Generally, it is not typical, and it will gradually become obvious when you grow into a teenager. There may be hirsutism, irregular menstruation and poor fertility. Second, polycystic ovary syndrome (PCOS) caused by ovary is characterized by high testosterone level, poor ovulation, hirsutism, irregular menstruation or amenorrhea. Third, the adrenal glands or ovaries grow tumors that can secrete androgens. The disease can occur at any time, and the course of the disease develops rapidly, characterized by shrinking breasts, large clitoris and no menstruation. This situation should be discovered and operated in time. All the above cases are organic diseases, and another is sudden hirsutism, with mild symptoms and no masculine manifestations, and menstruation may not be affected. This disease is more common in young girls, and it is not harmful, but it affects the face, and surgery or special drug treatment is ineffective. At present, the most commonly used method is laser hair removal.
