They can do that -- or they can have the opposite effect. It all depends on the relative levels of estrogen and testosterone you have. Both drop at meno, but testosterone levels can rebound naturally if they were reasonably high before.
What's happend appears to be that your testosterone levels have plummeted. My testosterone levels have always been very high, so when my estrogen levels dropped drastically the balance shifted in favor of testosterone. Everyone's different.
