Marty Makary, commissioner of the US Food and Drug Administration, has invited developers of testosterone replacement therapies for men to approach the agency to discuss a possible augmentation for their products. Specifically, this means pursuing a potential new indication for low libido in men with idiopathic hypogonadism, or sexual disfunction without a known cause. “New and emerging data suggest there may be an opportunity to help men suffering from symptoms that significantly affect quality of life,” he said in a statement issued on 16 April.
