Hey - a real question! Thanks. You'll notice the moment in the video where they describe the behaviors of post-boom rodents. To summarize/annotate - the rodents became disinterested in sex and display androgynous behavior of violence or reluctance to mate. This last bit isn't touched on much in the 8 min video - it is touched on much more in the actual study text and I believe there are longer videos of the data mentioning the behaviors in more detail. here is a section of article overviewing the parts related to the Breakdown of gender roles :
Breakdown Of Gender Roles
Developed world phenomenon.
Case Study: USA, Japan
We have observed that depopulation is an effect, so what is the cause? Perhaps there is more than one cause. The behavioural sink observed in the mouse utopia showed several abnormal social behaviours.
In the male mice, a limited space and a boom in population caused the males to fight more to be accepted. Since not all mice can be alpha males, the losers withdrew. With excess males fighting for dominance, older males gave up, leaving the females to fend for the family. These would then become increasingly aggressive and some even began attacking their own offspring.
Calhoun noted that as time progressed “…mothers fell short of maternal expectations”. In recent years there have been an increasing amount of cases [1], [2], [3], [4] of child neglect and abuse by human mothers that have made it to national headlines. It is not hard to speculate that there are many more we have not heard. In Australia, police have released data that attribute half of the nation’s infanticides to their mothers.
Since these are the more notorious cases which the media publishes, the less extreme cases go unnoticed, under reported or unreported in the media (in the last few decades there have been a string of stories in the media, which when examined as a whole tells us that women are starting to lose their natural instincts for nurture). We know that women in developed nations are suppressing maternal instincts, either intrinsically or extrinsically. It is also becoming more common for women to seek a sex-fueled lifestyle, something that was also observed in the mouse utopia.
“…the mice became more promiscuous…mice would roam around attacking others or mounting them irrespective of gender…”
“…phase C, the incidence of conception in females declined and the resorption in foetuses increased. Maternal behaviour was disrupted. Some mothers in desperate searches for quieter areas abandoned young that fell on the way…” – Tragedy in Mouse Utopia, Dr.J.R Vallentine
As the behaviour in the pen deteriorated, females would abandon their offspring leaving them to fend for themselves. With no parents around to teach them how to be well adjusted mice,
“…prematurely rejected, first by their fathers, then by their mothers, and then by established groups in the community, the young grew up without knowing how to behave, personally or socially as mice…” – Tragedy in Mouse Utopia, Dr.J.R Vallentine
Gender roles are vital in a social species, without that the break down of these lead to sub replacement fertility, depopulation, and finally, extinction.

Hope that helps.
