Elevated serum androgens are one of the most common clinical manifestations of polycystic ovary syndrome. A normal level of serum androgens is necessary to maintain a normal libido and reproductive function. If women have high levels of androgens, it will easily lead to obvious male characteristics in women, such as hirsutism, hairy armpits, beard, hair growth in the body, and acne, and also lead to irregular menstruation. Many women with polycystic ovary syndrome have hormone tests that indicate that androgens are higher than normal. Many women with polycystic ovary syndrome have hormone tests that indicate higher than normal levels of androgens, because high androgens can prevent the normal growth of follicles, leading to anovulation and sparse ovulation, as well as hirsutism and obesity. Many women with menstrual disorders or infertility are diagnosed with polycystic ovary syndrome after a sex hormone test indicating high androgens, combined with a comprehensive medical history. In conclusion, high androgens are the cause of polycystic ovary syndrome, which can lead to obesity, hirsutism, acne, menstrual disorders, scanty menstruation, non-ovulation, etc. Especially for women of childbearing age, if high androgens can lead to infertility, they need to be treated with oral hypoandrogenic therapy such as western hormones or birth control pills. More exercise, weight control and diet are very beneficial to the treatment of this disease.
