A huge number of men taking a testosterone drug in the United States have not even had their testosterone levels measured; the FDA’s approval of testosterone drugs is only for men who make too little of the hormone on their own, leading to a condition known as hypogonadism as well as men with endocrine tumors or those undergoing chemotherapy.

DePuy, a subsidiary of Johnson and Johnson, cornered a significant portion of the metal-on-metal hip implant market with its ASR Hip Resurfacing System and ASR Acetabular System. The ASR implant was based on its being substantially similar to another DePuy hip implant—the Pinnacle. The Pinnacle has suffered its share of problems as well, although it has not yet been recalled.
