Cynical part of me is wondering if the general apathy over it all is basically taking hold in those who care about others testing more while others aren't bothering as much. Going to stop short of the controversial statement but that may be linked to that chart...
A less controversial take would be this
Women and men’s immune systems work differently
In this Review the authors discuss some of the key differences that exist between male and female immune functions. They explain how these differences lead to sex biases in susceptibility to infections, inflammatory diseases and cancer. Moreover, they highlight the urgent need for immunologists...

It is increasingly important to acknowledge sex differences in immune responses when we consider the marked differences seen between males in females in various diseases. For instance, 80% of autoimmune disease occurs in females, women with acute HIV infection have 40% less viral RNA in their blood than men, men show an almost twofold higher risk of death from malignant cancer than women and antibody responses to seasonal influenza vaccines are consistently at least twice as strong in women than men. Generally, adult females mount stronger innate and adaptive immune responses than males. This results in faster clearance of pathogens and greater vaccine efficacy in females than in males but also contributes to their increased susceptibility to inflammatory and autoimmune diseases. In this Review, we explain how these immunological differences between the sexes reflect hormonal, genetic and environmental effects on the immune system that can change throughout life in humans.
