Hormone is a general term for hormones, including growth hormone, estrogen, androgen, and lactogen, etc. Human hormones belong to the category of endocrine and their secretion is regulated by the pituitary gland, hypothalamus, gonads and other tissues and organs. Hormones are very important for human health, development and maintenance of sexual function, for example, growth hormone deficiency may cause dwarfism, estrogen imbalance may cause sexual dysfunction, and abnormal hormone levels in women may easily cause menstrual disorders and even infertility. The secretion of hormones is affected by age, mostly decreasing with age, gradually increasing after entering puberty, reaching the peak of hormone secretion at the age of 20-30, and gradually decreasing at the age of 50-60. Hormone secretion is also related to diet, work and rest, and emotions, so you should avoid staying up late for a long time and keep a good mood.
