A new study shows that testosterone can improve bone density and anemia in men over 65 who are lacking in the hormone.

“After one year of treatment, older men with low testosterone significantly increased bone density and estimated bone strength compared to those on placebo,” says Dr. Christina Wang, co-author of the study, in a statement. “A larger and longer trial would be needed to determine if testosterone treatment reduces fracture risk.”

The treatment came with its downsides as men undergoing the therapy also had increased plaque buildup in their coronary arteries.

Researchers from LA BioMed partnered with 12 medical centers across the United States and the National Institute on Aging to conduct The Testosterone Trials. The series of seven tests studied the effects of testosterone therapy on men ages 65 and older compared to those without for one year.
