What are the implications of a Luteinizing Hormone (LH) level of 5.2 milli-international units per milliliter (mIU/mL) in a 42-year-old female (F) experiencing perimenopause symptoms?

From the Guidelines

The luteinizing hormone (LH) level of 5.2 mIU/mL is within the normal range for a woman in the follicular phase of her menstrual cycle, but interpretation depends on where you are in your cycle and other hormone levels. For perimenopause assessment, this single LH value is not sufficient for diagnosis. I recommend having additional tests including FSH, estradiol, and possibly AMH to better evaluate your hormonal status. These should ideally be drawn on day 3 of your menstrual cycle for accurate interpretation. Perimenopause is diagnosed based on a combination of symptoms (irregular periods, hot flashes, sleep disturbances, mood changes) and hormone patterns showing fluctuating levels. A complete evaluation would also include thyroid function tests to rule out thyroid disorders that can mimic perimenopause symptoms. If you're experiencing troublesome symptoms, treatments ranging from lifestyle modifications to hormone therapy might be appropriate, but these should be discussed with your healthcare provider after a complete evaluation, considering the potential risks and benefits as outlined by the U.S. Preventive Services Task Force 1. Key considerations include the increased risk of serious adverse events associated with hormone therapy, such as stroke, invasive breast cancer, and dementia, as noted in studies 1. Given the complexity of perimenopause diagnosis and management, a comprehensive approach that prioritizes symptom management, risk assessment, and individualized care is essential. This may involve lifestyle changes, such as diet and exercise modifications, as well as consideration of hormone therapy for symptom relief, while carefully weighing the potential benefits against the risks, as recommended by the U.S. Preventive Services Task Force 1. Ultimately, the decision to initiate hormone therapy should be made on a case-by-case basis, taking into account the individual woman's health status, symptoms, and preferences, with the goal of optimizing quality of life while minimizing morbidity and mortality.

From the Research

Perimenopause and Hormone Therapy

• The patient's luteinizing hormone (LH) level is 5.2 mIU/mL, which may indicate perimenopause 2.
• Perimenopause is a transition period characterized by physiological, affective, psychological, and social changes, with wide sexual hormone fluctuations until the onset of hypergonadotropic hypogonadic amenorrhea 3.
• Hormone therapy (HT) is an effective treatment for menopausal symptoms, including vasomotor symptoms and genitourinary syndrome of menopause 4.

Management of Perimenopause

• Correct perimenopause management should rely on individualized medical therapy and a multidisciplinary approach, considering lifestyle and food habits as part of general good health 3.
• The appropriate evaluation and evidence-based management of women in this transition is crucial, and two case vignettes can be used to highlight certain evaluation and treatment challenges 5.
• Hormonal contraceptives confer many non-contraceptive benefits for women approaching menopause, including treatment of abnormal uterine bleeding, relief from vasomotor symptoms, and endometrial protection in women using estrogen therapy 3.

Hormone Therapy Considerations

• The risk-benefit ratio and safety profile of HT differ markedly by clinical characteristics of the participants, especially age, time since menopause, and comorbidity status 4.
• HT may be unsuitable for some women, including those at increased risk of cardiovascular disease, increased risk of thromboembolic disease, or increased risk of some types of cancer 2.
• The menopause transition is a disruptive process that can last for over a decade and causes symptoms in a majority of women, and clinicians should recognize early signs and symptoms of the transition and be prepared to offer treatment to mitigate these symptoms 6.
