In this observational study, researchers from Boston University School of Medicine (BUSM), investigated the effects of testosterone treatment in 255 hypogonadal men between the ages of 33-69 and followed them for a period of five years.
They found that men treated with testosterone therapy experienced a gradual reduction of their total cholesterol, low density lipoprotein cholesterol, triglycerides and increased high density lipoprotein.
“In addition to improving their cholesterol levels, we found that the testosterone treatment resulted in marked reductions in systolic and diastolic blood pressure as well, suggesting amelioration of hypertension,” lead author Abdulmaged M. Traish, MBA, PhD, professor of biochemistry and urology as well as Research Director of the Institute of Sexual Medicine at BUSM explained.
Traish found this treatment also reduced fasting blood glucose and hemoglobin A1c, a surrogate marker of hyperglycemia, suggesting that testosterone treatment may improve insulin sensitivity and hyperglycemic control.
It also reduced the levels of inflammatory biomarkers such as C-reactive protein (CRP) and markers of liver dysfunction such as alanine aminotransferase and aspartate aminotransferase, suggesting reduction in the inflammation responses.
The study is published in the International Journal of Clinical Practice.
