How different would civilization be if humans had "mating season" ?

Let's imagine, a world where 10 month a year, men and women don't care about each other. However, twice a year, during 2-3 weeks, non pregnant women produce pheromone that men can't resist and start calling every boy around to breed with them.

How would this impact the civilisation ?

I know about David Brin's *glory season * but not sure whether any other writer explored that idea.
