From the Guidelines

Increased testosterone levels in a 35-year-old female are most commonly caused by Polycystic Ovary Syndrome (PCOS), which affects 5-10% of women and is characterized by multiple ovarian cysts, irregular periods, and hormonal imbalances. Other potential causes include congenital adrenal hyperplasia, adrenal or ovarian tumors, Cushing's syndrome, and certain medications like anabolic steroids or danazol 1. Insulin resistance and obesity can also contribute to elevated testosterone as fat tissue converts other hormones to testosterone 1. Some women may have idiopathic hyperandrogenism without an identifiable cause. Symptoms of high testosterone include irregular periods, acne, excessive body hair growth, male-pattern baldness, deepening voice, and increased muscle mass. Diagnosis typically involves blood tests to measure hormone levels, imaging studies like ultrasound, and sometimes adrenal function tests 1. Treatment depends on the underlying cause but may include lifestyle modifications (weight loss, diet changes), hormonal contraceptives to regulate periods and reduce testosterone, anti-androgen medications like spironolactone (50-200mg daily), metformin (500-2000mg daily) for insulin resistance, or specific treatments for tumors if present 1. Women experiencing symptoms of high testosterone should consult a healthcare provider for proper evaluation and individualized treatment. Key points to consider in the diagnosis and management of high testosterone levels in women include:

  • PCOS is a common cause of high testosterone levels in women, and diagnosis is based on clinical and biochemical criteria 1
  • Other potential causes of high testosterone levels should be considered, including congenital adrenal hyperplasia, adrenal or ovarian tumors, and certain medications 1
  • Insulin resistance and obesity can contribute to elevated testosterone levels, and lifestyle modifications may be beneficial in reducing testosterone levels 1
  • Treatment of high testosterone levels depends on the underlying cause, and may include hormonal contraceptives, anti-androgen medications, and specific treatments for tumors if present 1.

From the Research

Possible Causes of Increased Testosterone Levels in a 35-Year-Old Female

  • Polycystic Ovary Syndrome (PCOS): A common endocrine disorder that can cause high levels of testosterone in women 2.
  • Hyperandrogenism: A condition characterized by excessive levels of androgens, such as testosterone, which can be caused by various factors, including PCOS, adrenal gland disorders, and certain medications 3.
  • Autoimmune disorders: Some studies suggest that autoimmune disorders, such as those affecting the follicle-stimulating hormone receptor (FSHR) or luteinizing hormone receptor (LHR), may contribute to hyperandrogenism in some women 4.
  • Hormonal imbalances: Imbalances in hormones such as luteinizing hormone (LH), follicle-stimulating hormone (FSH), and insulin can contribute to high testosterone levels in women 5, 6.

Diagnostic Features of PCOS

  • High levels of testosterone and androstenedione 5
  • Elevated LH/FSH ratio 5
  • Increased anti-Mullerian hormone (AMH) levels 5
  • Enlarged ovarian volume 5
  • Hyperandrogenism and ovulatory dysfunction 2

Treatment Options for PCOS

  • Hormonal therapies, such as drospirenone/ethinyl estradiol, which can help regulate hormonal imbalances and reduce testosterone levels 6
  • Lifestyle modifications, such as diet and exercise, which can help improve insulin sensitivity and reduce androgen levels 2
