Perimenopause I

Four men were laughing about their "hormonal" wives when the only woman at their level crossed the room, dropped her jacket on the floor, and showed them the sleeves she'd cut out of her blouse.

What is actually happening, why a single blood test cannot see it, and what the evidence says helps.
