In order to address low testosterone, it can be important to investigate the reasons for lowered production. Testosterone plays an instrumental role in supporting energy levels, confidence, and mental clarity (Straftis & Gray, 2019). Additionally, testosterone is considered neuroprotective and has been shown to increase neurogenesis, the process of growing new neurons in the brain (Spritzer & Roy, 2020).
Table 1 shows the sex-stratified demographic characteristics of the sample and descriptive statistics. We also assessed the sensitivity of our results to an alternative coding strategy where we used log-transformed testosterone values instead of raw concentrations. Statistical significance of the overall effect of total testosterone was tested with a Wald test.
The survey was methodologically designed as a cross-sectional sequel to the prospective Zurich cohort study (38), e.g., the instruments and the age structure were parallelized. Furthermore, exogenous T administration has not only been related to depression but also to hypomania and even mania (23–28). In sum, there appears to be insufficient evidence to conclude that low T levels are routinely involved in the pathogenesis of MDD in men (15).
Beyond the gonadal hormone T characterizing the atypical depression subtype, the effect size was particularly striking for BMI. In our study, T levels were actually higher in the melancholic depression subtype compared to both other groups, although they only differed significantly from the atypical group. This is a preliminary study examining differences of serum T levels in empirically derived symptom-based depression subtypes and a healthy control group in a Swiss community sample of male adults.
Is there an ideal age to start exercising for testosterone benefits? If you suspect you have low testosterone, consult with a healthcare professional. Focus on a balanced diet rich in protein, healthy fats, and micronutrients to support natural testosterone production. Consulting with a healthcare professional or certified personal trainer is recommended to develop a personalized exercise plan tailored to your specific needs and goals. Testosterone levels naturally decline with age, and individual responses to exercise can differ significantly. Can vary based on age, genetics, and pre-existing health conditions. Daily saliva samples (AM, noon and PM) were collected, blood pressure, arterial elasticity measured as pulse wave velocity and PANAS-X mood questionnaire were performed before, during and at the end of 2 weeks pomegreat® pure juice intake.

The current associations of higher testosterone with sleep problems and fatigue would be in agreement with this line of research. As a final step, we assessed the sensitivity of our results to an alternative coding strategy where we used log-transformed testosterone values instead of raw concentrations. As for the analysis using splines (Supplementary Figs. 3 and 4), the sensitivity analysis supported the results of the main analysis with regard to the association between higher testosterone and sleep problems in men. The predictions were obtained from cubic spline regression models with sampling weights, adjusting for age, BMI, alcohol use, smoking, physical activity, and pregnancy.
