Swimming may raise androgens in men. The main source of androgens is the testes, which secretes testosterone that can be converted into androgens, and the adrenal cortex and the ovaries in women can also be sources of testosterone. In daily life, appropriate physical exercise, such as swimming, jogging, jumping rope, playing tai chi, etc., may promote the secretion of sex hormones as well as the production of testosterone, which in turn elevates the level of androgens in the blood. Apart from that, eating cholesterol-rich foods, such as animal offal, may also enhance the level of androgens, as cholesterol is an important ingredient in the synthesis of sex hormones, but it is not recommended to over-eat cholesterol-rich foods to avoid indigestion or obesity. People who need to boost their androgens should also maintain a healthy lifestyle, and if they need to use medication to boost their androgens they need to do so under the guidance of a doctor.
