From the Guidelines

Elevated LH and FSH in a 23-year-old woman is most likely indicative of primary ovarian insufficiency or premature ovarian failure, which requires comprehensive evaluation and potential hormone replacement therapy to prevent long-term complications. This condition can significantly impact fertility and hormone production, leading to symptoms such as irregular or absent periods, hot flashes, night sweats, vaginal dryness, and mood changes. The diagnosis should be approached with a focused history and examination, pelvic ultrasound, and focused laboratory evaluation, including additional hormone tests like estradiol, anti-Müllerian hormone, prolactin, and thyroid function 1. Given the complexity of distinguishing between functional hypothalamic amenorrhea (FHA) and polycystic ovary syndrome (PCOS), especially in cases with polycystic ovarian morphology, the LH to FSH ratio may serve as a useful diagnostic tool, with a ratio <1 often seen in FHA patients and a ratio >2 commonly observed in PCOS patients 1. Treatment options, including hormone replacement therapy and fertility preservation methods like egg freezing, should be discussed with a gynecologist or reproductive endocrinologist to address the individual's specific needs and concerns. It's essential to prioritize the patient's quality of life, morbidity, and mortality outcomes when managing this condition, considering the potential long-term effects on bone density, cardiovascular health, and mental well-being. A comprehensive and multidisciplinary approach is necessary to provide the best possible care for women with elevated LH and FSH levels, ensuring timely intervention and support to mitigate the risks associated with premature ovarian failure. Key considerations include:

  • Comprehensive diagnostic evaluation
  • Hormone replacement therapy
  • Fertility preservation options
  • Management of associated symptoms and long-term complications
  • Multidisciplinary care approach
  • Patient education and support.

From the Research

Elevated LH and FSH in a 23-Year-Old Woman

Elevated luteinizing hormone (LH) and follicle-stimulating hormone (FSH) levels in a 23-year-old woman can be indicative of several conditions. Some possible causes include:

  • Polycystic ovary syndrome (PCOS) 2, 3
  • Ovarian tumors or cysts, such as inhibin B-producing thecomas 4
  • Hormonal imbalances or disorders

Polycystic Ovary Syndrome (PCOS)

PCOS is a common endocrinological disorder among women of reproductive age, characterized by chronic ovulatory dysfunction, hyperandrogenism, and elevated LH/FSH ratio 2, 3, 5. Studies have shown that women with PCOS often have higher levels of LH and LH/FSH ratio compared to normal ovulatory controls 2, 3. However, the LH/FSH ratio may not be a reliable diagnostic criterion for PCOS, as it can be influenced by various factors, including body mass index (BMI) 5.

Diagnostic Considerations

When evaluating a woman with elevated LH and FSH levels, it is essential to consider the following:

  • Hormonal assays, including LH, FSH, and androgen levels 2, 3
  • Pelvic ultrasound to rule out ovarian tumors or cysts 4
  • Clinical evaluation, including medical history, physical examination, and assessment of menstrual regularity and fertility 4
  • BMI and its potential impact on LH/FSH ratio 5

Hormonal Imbalances or Disorders

Elevated LH and FSH levels can also be indicative of hormonal imbalances or disorders, such as:

  • Hyperandrogenism, which can be associated with PCOS or other conditions 2, 3
  • Inhibin B-producing tumors, which can affect LH and FSH levels 4
  • Other endocrinological disorders, such as thyroid dysfunction or hyperprolactinemia 5
