What advice to give to a 37-year-old male with a testosterone (T) level of 188 ng/dL, which has decreased from 218 ng/dL in March and 199 ng/dL in August, who is working on lifestyle changes to increase his testosterone levels?

From the Guidelines

I would strongly advise this 37-year-old male to continue his lifestyle modifications and consult with an endocrinologist or urologist for further evaluation, as his testosterone levels (188-218 ng/dL) are consistently below the normal adult male range (typically 300-1000 ng/dL) 1. While continuing lifestyle improvements like regular exercise (especially strength training), adequate sleep (7-9 hours nightly), stress reduction, maintaining healthy body weight, and consuming a balanced diet rich in zinc, vitamin D, and healthy fats, medical intervention may be necessary. These consistently low readings suggest a potential underlying condition requiring medical assessment. Testosterone replacement therapy might be considered after proper evaluation, which could include injections (typically 50-100mg weekly), topical gels (50-100mg daily), or patches. Before starting any treatment, additional testing should be done, including luteinizing hormone, follicle-stimulating hormone, prolactin levels, and a complete metabolic panel to identify the cause of low testosterone, whether primary (testicular) or secondary (pituitary/hypothalamic) 1. It is essential to note that the American College of Physicians suggests that clinicians should reevaluate symptoms within 12 months and periodically thereafter, and discontinue testosterone treatment in men with age-related low testosterone with sexual dysfunction in whom there is no improvement in sexual function 1. Lifestyle changes, such as smoking cessation, regular dynamic exercise, weight loss, a healthy diet, and moderate alcohol consumption, are also crucial in reducing cardiovascular risk and improving erectile function 1. Given the potential benefits and harms of testosterone treatment, it is crucial to weigh the pros and cons and consider the patient's preferences and values before making a decision 1. In this case, the most recent and highest quality study 1 suggests that testosterone replacement therapy may be beneficial for men with symptomatic hypogonadism, but it is essential to carefully evaluate the patient's symptoms and medical history before initiating treatment.

From the Research

Testosterone Levels

  • The user's testosterone level is 188, which is lower than the levels in March (218) and August (199) 2, 3.
  • Testosterone levels can fluctuate due to various factors, including lifestyle, nutrition, sleep, and stress 3.
  • A decrease in testosterone levels can be caused by factors such as nutritional deficiency, particularly of zinc, magnesium, and vitamin D, as well as low polyphenol intake and high levels of mental and oxidative stress 3.

Lifestyle Modifications

  • Lifestyle modifications, including adequate sleep, exercise, and weight loss in patients with obesity, are essential for managing testosterone levels 2.
  • A healthy diet, rich in nutrients such as zinc, vitamin D, and polyphenols, can help support testosterone production 2, 3.
  • Exercise, particularly resistance training, can also help improve testosterone levels 2.

Vitamin D Status

  • Vitamin D status can impact the cardiometabolic effects of testosterone replacement therapy in men with late-onset hypogonadism 4.
  • Men with low vitamin D status may not experience the same benefits from testosterone replacement therapy as those with adequate vitamin D levels 4.

Testosterone Replacement Therapy

  • Testosterone replacement therapy (TRT) aims to improve symptoms and signs of testosterone deficiency by increasing serum testosterone levels to a physiologic range 5.
  • TRT has been used for over 70 years, and various preparations and formulations have been developed to improve pharmacokinetics and patient compliance 5.
  • However, the safety of long-term TRT in late-onset hypogonadism is not well established, and clinicians must consider the unique characteristics of each patient to provide the safest and most beneficial results 5.
