None. Nothing happens. Depending upon when the male of the species disappears, and I’ll use your theory to mean that males never happen, then primates never evolve. Instead insects evolve after the death of the dinosaurs. Giant cockroaches become sentient. They pretty much follow the evolution of primates. Various branches. One roachus sapiens to lead them all. But the lack of testosterone allows the bugs to work together without internecine war.
The bugs create space flight when men would have been creating airplanes. Working together the bugs begin to travel to other worlds. Since insects do not care about the individual, they use slow ships with multiple generations to reach the near stars. They create a huge galaxy spanning hive. None of them have to communicate with each other. They are all one.
Eventually they meet other beings. Maybe some of them are monkey based. But it matters not. The bugs are the best of the best. Eventually the bugs take over the universe.
But they never make a decent Star Trek movie.
