just answering the title question. yes, hormones cause fatigue. or rather, they can cause fatigue, just as well as they can relieve it.
sex hormones aren't the only ones we need in the right amounts to function properly, even vitamin d is really a hormone (deficiency causes depression).
if you are more fatigued than you think you should be, and not currently depressed or anything else that would easily explain it, you need to get your hormone levels checked. as well as a whole lot of other things. like, what if it's a vitamin that you lack, or your blood is too thin, or... well, i think you get what i mean.
