While testosterone exerts a positive effect in men with baseline anemia, it can lead to polycythemia in over 20% of men treated on TRT. Future prospective studies with longer follow-up will determine if such association between TRT and male breast cancer truly exists. Current guidelines on the frequency of PSA monitoring and role of pre-treatment transrectal ultrasound guided prostate biopsy are lacking. In the most recent study by Pastuszak et al., the authors retrospectively reviewed a cohort of 103 men who underwent prior radical prostatectomy and were treated with TRT. If you still have problems getting to or staying asleep, get medical advice from a healthcare provider. Poor sleep and sleep disorders have been linked to erectile dysfunction. The Mediterranean diet, for one, has been shown to improve erectile function. This wards off heart-related health problems while reducing your risk for ED. A healthy diet helps keep blood pressure down and blood vessels open, making blood flow easier. It does this by stimulating Leydig cells (which are the main source of testosterone for males), testosterone and sperm production. The hormone has been shown to enhance sexual performance. The testicles begin secreting testosterone around seven months of gestation. Throughout the male lifecycle, testosterone helps control the development of secondary male characteristics, such as a deep voice, muscle growth, and bone mass. Like your penis, your testes benefit from a constant supply of blood rich in nutrients. Some athletes have used testosterone tablets, creams, gels or even injections to enhance their performance. This is because the body's ability to absorb blood sugar is decreased. In addition, certain medications can cause testosterone deficiency, as can diseases of the pituitary gland. Testicular neoplasms can also cause a low testosterone level. It's also been touted to boost sperm and semen production, and increase sensitivity in the scrotum. TRT, when given to appropriately selected patients with vigilant monitoring as outlined in this review and in Table 1, can bring improvements in quality-of-life, energy level, libido, muscle mass, cognition and bone density. Data on the safety of TRT specific to our aging population is not currently available; however TRT has been linked to prostate cancer, BPH, polycythemia and OSA.
