The reasons for low testosterone in women are caused by the following aspects: First, it may be caused by the poor physical condition of women, because normal testosterone synthesis in the body requires certain substances as a basis, such as cholesterol, vitamins and essential amino acids, etc. If the substances are lacking in the body, the testosterone content will be reduced accordingly. Secondly, it may be the problem of testosterone generation and regulation process. Testosterone generation needs the precise regulation of hypothalamus-pituitary-gonadal axis to ensure that the amount of testosterone can neither be high nor low, and if the axis has problems, it will lead to the decrease of testosterone content. Thirdly, it may be that testosterone is inactivated too much in the body, that is, testosterone is inactivated in the body by organs such as the liver and then excreted out of the body through the kidneys, resulting in testosterone production less than the amount excreted in the body, which can also lead to a decrease in testosterone content in the blood.
