Oestradiol measured by Liquid Chromatography-Mass Spectrometry (LCMS)

Oestradiol is a key hormone influencing reproductive health and overall hormonal balance, measured precisely by LCMS to assess well-being in both women and men.

📋 About This Biomarker

Oestradiol is a vital hormone in the estrogen family, acting like a key player in the body's hormonal orchestra. In women, it's essential for regulating the menstrual cycle, developing eggs in the ovaries, and preparing the uterus for pregnancy. Beyond reproduction, oestradiol supports bone health, influences mood, and affects skin and cardiovascular health. In men, although present in smaller amounts, it contributes to bone maintenance, brain function, and modulating libido. Oestradiol is produced mainly in the ovaries for women and in the testes and fat tissue for men. Measuring oestradiol levels using Liquid Chromatography-Mass Spectrometry (LCMS) provides a highly accurate picture of this hormone's status in your blood, offering valuable insights into your reproductive health and overall hormonal balance.

🎯 Why We Test This

Testing oestradiol levels provides valuable insights into your hormonal health. For women, it helps evaluate menstrual irregularities, fertility issues, symptoms of menopause, or conditions like PCOS. For men, it can assist in understanding symptoms like low libido or bone health concerns. Measuring oestradiol supports healthcare providers in diagnosing hormonal imbalances and crafting effective plans to manage or treat underlying conditions, promoting overall health and quality of life.

⚠️ What Affects It

Various factors can influence oestradiol levels. In women, age and the menstrual cycle phase cause natural fluctuations - levels peak during ovulation and decrease after menopause. Pregnancy significantly elevates oestradiol levels. Body fat also plays a role since fat tissue produces estrogen; thus, weight changes can impact levels. Medications like hormonal contraceptives or hormone replacement therapy can alter oestradiol levels. Health conditions such as polycystic ovary syndrome (PCOS), ovarian cysts, or adrenal gland disorders may affect oestradiol. In men, factors like obesity, liver disease, and certain medications can influence oestradiol levels.

📈 How to Improve

Balancing oestradiol levels often involves lifestyle choices and, when necessary, medical guidance. If levels are high or nearing high, maintaining a healthy weight through a balanced diet and regular exercise can help, as excess body fat can increase estrogen production. Limiting alcohol and avoiding exposure to environmental estrogens (like certain plastics) may also be beneficial. If levels are low or approaching low, incorporating a nutrient-rich diet and engaging in weight-bearing exercises can support hormonal health and bone strength. In some cases, healthcare providers may discuss options like hormone therapy. It's important to consult a healthcare professional before making significant changes to ensure they are appropriate for your individual health needs.

📊 Understanding Your Results (pmol/L)

Low (< 40 pmol/L)
Lower-than-normal oestradiol levels indicate reduced estrogen production. In women, this is common after menopause or might result from conditions like excessive exercise or eating disorders. Symptoms may include hot flushes, night sweats, decreased bone density, or fatigue. In men, low oestradiol levels can affect bone health and energy levels. Identifying low levels is important to address symptoms and support overall health, possibly through lifestyle adjustments or medical interventions advised by a healthcare provider.
Optimal (40 - 160 pmol/L)
Oestradiol levels within the normal range indicate a balanced hormonal state. For women, it signifies a regular menstrual cycle and healthy reproductive function. For men, it reflects proper hormonal regulation supporting various body functions. Balanced oestradiol levels contribute to overall health, including strong bones, healthy skin, and stable mood. It means the body's hormonal systems are functioning smoothly, supporting well-being and vitality. When oestradiol levels approach the upper limit, it might be a sign of an impending hormonal change. In women, this could reflect the ovulatory phase of the menstrual cycle or early stages of pregnancy. However, consistently high-normal levels may warrant further investigation for conditions like estrogen dominance or hormonal imbalances. In men, levels nearing the high end might suggest subtle hormonal shifts affecting well-being. Monitoring these levels can aid in early detection and proactive health management. Oestradiol levels near the lower limit may suggest decreasing estrogen activity. In women, this might occur during the early phase of the menstrual cycle or signal the onset of menopause. Symptoms can include irregular periods, hot flushes, or mood changes. In men, slightly low-normal levels are usually not concerning but can be monitored if symptoms arise. Keeping an eye on these levels helps anticipate and manage hormonal transitions effectively.
High (> 160 pmol/L)
Higher-than-normal oestradiol levels may indicate a hormonal imbalance. In women, this could be associated with conditions like PCOS, estrogen-producing tumors, or early puberty in girls. Symptoms might include irregular menstrual cycles, weight gain, or mood swings. In men, elevated oestradiol can lead to decreased libido, fatigue, or gynecomastia (enlarged breast tissue). It may suggest hormonal shifts due to factors like obesity or liver issues. Identifying high oestradiol levels helps in understanding underlying health concerns and exploring appropriate management options with a healthcare provider.
