Because hyperandrogenism is characterized by elevated male sex hormone levels, symptoms of hyperandrogenism in men are often negligible. Hyperandrogenism in women is typically diagnosed in late adolescence with a medical evaluation. The medical evaluation usually consists of a pelvic exam, observation of external symptoms, and a blood test measuring androgen levels. Symptoms may include the following:

Women
Hyperandrogenism, especially high levels of testosterone, can cause serious adverse effects if left untreated. High testosterone levels are associated with other health conditions such as obesity, hypertension, amenorrhea (cessation of menstrual cycles), and ovulatory dysfunction, which can lead to infertility. Prominent signs of hyperandrogenism are hirsutism (unwanted growth of hair, especially in the abdominal region and on the back), adult acne, deepening of the voice, and alopecia (balding).Hyperandrogenism has also been observed to increase insulin tolerance, which can lead to type two diabetes and dyslipidemia, such as high cholesterol. These effects may have psychological impacts, sometimes leading to social anxiety and depression, especially in adolescent girls and young women. Paired with obesity and hirsutism, it can cause the individual to have low self-esteem. Men
Administration of high-dose testosterone in men over a course of weeks can cause an increase in aggression and hypomanic symptoms, though these were see in only a minority of subjects. Acute high-dose anabolic-androgenic steroid administration in males attenuates endogenous sex hormone production and affects the thyroid hormone axis. Effects on mood and aggression observed during high-dose anabolic-androgenic steroid administration may occur secondarily to hormonal changes.
It makes thecal cells more responsive to luteinizing hormone. Therefore, obesity increases ovarian androgen production. Additionally, obesity elevates inflammatory adipokines which leads to not only adipogenesis, but also heightened insulin resistance. Cushing’s syndrome
Cushings syndrome develops as a result of long-term exposure to the hormone cortisol. Cushings syndrome can either be exogenous or endogenous, depending on whether it is caused by an external or internal source, respectively. The intake of glucocorticoids, a type of corticosteroid, is a common cause for the development of exogenous Cushings syndrome. Endogenous Cushings syndrome can occur when the body produces excess cortisol. This occurs when the hypothalamus of the brain signals to the pituitary gland with excess corticotropin-releasing hormone, which in turn secretes adrenocorticotropin hormone (ACTH). ACTH then causes the adrenal glands to release cortisol into the blood. Signs of Cushings syndrome include muscle weakness, easy bruising, weight gain, male-pattern hair growth (hirsutism), coloured stretch marks, and an excessively reddish complexion in the face. Cushings syndrome can cause androgen excess and hence the signs and symptoms of hyperandrogenism. Congenital adrenal hyperplasia
Congenital adrenal hyperplasia (CAH) describes a group of autosomal recessive disorders that cause a lack of an enzyme necessary for the production of cortisol and/or aldosterone, steroid hormones produced by the adrenal cortex. Most cases of CAH are due to 21-hydroxylase deficiencies. The heightened androgen levels seen in congenital adrenal hyperplasia affect the hypothalamic–pituitary–gonadal axis.
