If you’re experiencing symptoms of low testosterone, it’s crucial to seek professional guidance to address these issues safely and effectively. In men, it’s diagnosed when levels fall below 300 nanograms per deciliter (ng/dL). Low testosterone, or hypogonadism, occurs when the body doesn’t produce enough testosterone. For women, testosterone is produced in smaller amounts but is essential for bone strength and sexual interest. It helps in the development of male physical features like body and facial hair, deeper voice, and muscle strength. Both males and females produce testosterone in their bodies, but males typically have much higher levels of it. In addition, thyroid hormones and thyroid status have varied effects on the pharmacokinetics and actions of other drugs. Prescription hormones from Male Excel require an online consultation with one of our licensed healthcare providers who will evaluate whether or not you are an appropriate candidate and review benefits and potential side effects with you prior to prescribing. Through Male Excel's hormone optimization initiatives, Dr. Fotinos emphasizes that many men are told their testosterone is “normal†even when symptoms clearly indicate functional deficiency. Men experience a more gradual hormonal decline, often called andropause. Excess androgens can trigger breakouts and hair loss along the temples, while low thyroid function causes brittle hair and dry skin. Estrogen supports cerebral blood flow and neuroplasticity. Declining estrogen promotes visceral fat accumulation around the midsection. Hormonal imbalances can shift where and how your body stores fat. Research published in Fertility and Sterility confirms that progesterone deficiency is one of the most common causes of irregular menstrual patterns in women over 35. Fluctuations in estrogen and progesterone directly affect your menstrual cycle. This tool is for informational and educational purposes only and is not medical advice.

However, he would likely be experiencing severe symptoms of low T. Before we look at the charts, you must understand how lab "reference ranges" are created. There may be extra risks for women with cardiovascular or liver disease, or certain types of cancer. Menopause is often the reason why women experience a change in their sex drive. "The lab ranges, however, can vary greatly from highs of 40 to 120 ng/dl." In this article, we look at how testosterone levels change with age, how to check your testosterone levels, and when it’s worth exploring further. Testosterone levels drop naturally with age — but what’s a normal rate of decline? However, significant hormonal deficiencies often require medical intervention such as BHRT or TRT to restore levels to an optimal range. Among sex hormones, low testosterone in men and estrogen-progesterone imbalances in women are the most frequently diagnosed conditions. Testosterone replacement therapy restores testosterone to optimal levels in men with documented deficiency. So, if you’re wondering, "What are good total testosterone levels by age, these figures should answer that question. Checking testosterone levels is as easy as having a blood test. Testosterone therapy is approved for the treatment of delayed male puberty and abnormally low production of testosterone secondary to malfunction of the testes, pituitary or hypothalamus. That's why medications that lower testosterone levels (for example, leuprolide) are common treatments for men with prostate cancer. Part of this may be due to the difficulty defining "normal" testosterone levels and "normal" behavior. Some women with high testosterone levels develop frontal balding. In general, guidelines aim for symptom improvement within the normal physiologic male range rather than supraphysiologic levels (Bhasin et al., Journal of Clinical Endocrinology & Metabolism, 2018). If testosterone rises above the female physiologic range, the risk of androgenic adverse effects increases and the treatment logic starts to break down (Parish et al., Climacteric, 2021; Parish and Kling, Menopause, 2023).
