Hey guys,
I saw this and thought of you all. I had spoken about this will Bobby and how using pheromones could perhaps be helpful in controlling the populations. I wasn’t that far off…

That’s right. It’s the old decoy. The males can continue with their roles in dominance and natural behavior without the consequence of pregnancy. In lab mice, we know that you can induce pseudopregnancy just by mating females with vasectomized males in order to provide appropriate surrogates for exogenous embryo implantation. But without the embryo implantation, you’ve created a period where the female is not going to be effectively breeding (complete with vaginal mucosal plug).
