In a world of gender inequalities that disadvantage women and girls, publishing a report on how men are not being reached by health services and are not exercising their right to health may seem counterintuitive. It was indeed perplexing for me to learn that men were less likely than women to know their HIV status and less likely to access and adhere to HIV treatment. As a consequence, more men are likely to die of AIDS-related illnesses than women. As the world strives to reach the high levels of HIV service coverage required to end AIDS as a public health threat, this blind spot in the response to HIV can no longer be ignored.
