I use the phrase 'unsung heroes' for men who are living with involuntary childlessness and coming to terms with infertility. If resources and conversation around support for women need to be more mainstream then they can feel invisible for men. Hence, unsung heroes. 

Fortunately there are some great sites and researchers out there providing invaluable work to change that perception. I know from feedback for this site that these resources provide comfort and information to our male contributors and their friends and family, helping to push past feeling of isolation.
