This is a news report on a presentation at the European and International Conference on Obesity. The research was funded by Bayer, who sells Nebido, the form of testosterone used in this study.
The researchers collected data since 2004 of 471 men with functional hypogonadism, or low testosterone production, and obesity from a German urological practice.
Around 58% of the men received an injection of testosterone every 3 months for the duration of the study, while the remainder chose not to have the treatment and therefore acted as controls. The average age of the participants was 61.57.
Medical staff administered and documented all injections at a doctor’s office, which assures that all participants received the treatment in a consistent manner. No participants dropped out of the study.
The men who received testosterone lost on average 23 kilograms (kg) (equivalent to 20% body weight) during the study period, while those who did not receive treatment gained an average of 6 kg.
Body mass index (BMI) correspondingly decreased by an average of 7.6 points in those who received testosterone therapy, compared with an increase of 2 points in the control group.
Waist circumference, which is a risk factor for cardiometabolic disease, decreased by an average of 13 centimeters (cm) in the treatment group, compared with a 7 cm increase in the control group.
The testosterone-treated men also had less internal (visceral) fat by the end of the study period. They may have had a lower risk of cardiovascular disease than those who did not receive treatment.
Overall, 28% of men in the control group had a heart attack, and 27.2% had a stroke during the study period. There were no major cardiovascular events in the men who received testosterone therapy.
Likewise, while more than 20% of the control group developed type 2 diabetes during the study period, nobody in the treatment group developed the condition.
The researchers also presented data specific to men who were eligible for bariatric surgery. This is a surgical treatment for obesity, which encompasses gastric band, gastric bypass, and gastric sleeve surgery.
Although bariatric surgery is a proven means of achieving weight loss, there are serious risks associated with the surgery, which does not always have positive outcomes.
This part of the study included 76 men with class 3 obesity (a BMI of 40 or above), making them eligible for bariatric surgery. Of these, 59 received testosterone treatment and lost 30 kg on average.
The BMI of the men also reduced by an average of 10 points, which could be enough to take them out of the highest obesity class, provided their BMI was less than 50 to begin with.
