While excluding the obvious reproductive issues. Most politicians and heads of state worldwide are male. Few countries have complete gender equality in the military and most of those who serve are male. The majority of corporate leaders are male. And most dangerous jobs are handled males.
The sudden loss of most males from the world's population would lead to a temporary time of Chaos. Many countries around the world may actually break down at least for a Time.
Eventually of course all these jobs would be taken over by women, but that might take years if not decades.
On the plus side so many dead people would mean more resources and land to be divided up among the survivors.
I suggest you check out y the last man alive comic as it deals with this subject.
Of courseif the loss of males is more gradual in society will have more time to adjust. There will still be a time of chaos as Society first tries to deny what's going on, and then begins to panic as the truth becomes unex capable. Finally people begin to accept and try adjusting to the new reality.
There also would still be an interlude as it would take time to train a large body of woman to take societal roles usually taking by men. (And a lot of women would probably thrust into positions that they aren't qualified for out of necessity) but because there is more time to make the adjustment worldwide Society is less like to completely collapse.
