Previous studies of testosterone-replacement therapy have shown changes in body composition, usually in the form of increased lean mass and decreased fat mass. Farid Saad, of Bayer Pharma in Germany, and colleagues reviewed data in a prospective registry of middle-age and older men, mean age 60.6 years, who received testosterone-replacement therapy for two to five years. More than half of the patients had four years of follow-up.
The objective was to determine the long-term effects of normalization of the men’s testosterone. Standard treatment was 1,000-milligram initial dose, followed six weeks later by 1,000 milligrams and then 1,000 milligrams every 12 weeks after that. The baseline testosterone averaged 287 nanograms per deciliter. Baseline weight averaged 236 pounds, and 95 percent of the men had a baseline body mass index of greater than 25, including 71 percent of men who were obese (BMI 30 to 40) or morbidly obese (greater than or equal to 40). The men had a median waist circumference of 42.2 inches.
Similar to the weight distribution, 4 percent of the men had waist circumferences that were less than 37 inches, and 68 percent had waists greater than or equal to 40 inches. Testosterone levels normalized (greater than or equal to 350 nanograms per deciliter) within six to nine months and remained stable throughout follow-up. Annual measurements showed that testosterone levels significantly exceeded baseline values beginning at 12 months and continuing to the end of follow-up. Similarly, bodyweight declined significantly within 12 months and continued to decline for as long as five years.
As well, weight declined significantly between annual measurements, beginning at year two. More than half of the men lost at least 33 pounds, and almost a third lost 44 pounds or more. Similarly, 86 percent had a least a two-inch reduction in waist circumference, and 46 percent dropped six inches or more.
“I don’t know many treatments where more than 90 percent of patients respond in a positive way to the treatment,” the lead study author commented. His bottom line: “There is no evidence of an increased risk of prostate cancer in testosterone-treated men.”
