Estrogen seems to have very similar effects to serotonin on memory and behavior (as I posted about serotonin earlier this year). This study was human, so the results are even more relevant.
How women navigate depends on their menstrual cycles
"...We found that during the ovulatory phase when estrogen peaks, women tend to use response memory to solve the maze. Response memory is like basic habitual motor memory, such as turning right then left to get to work. However, when women are in the mid/late luteal phase of the cycle, just prior to menstruation when progesterone peaks and estrogen also rises again, they are more likely to use spatial memory. Spatial memory is what you’d use if you encountered a roadblock on your way to work, and had to mentally pull up a map of the neighborhood to think of an alternate route."
