Dr. Sarah Hill's new book, "The Period Brain," explores the hidden influences of hormones on women's brains and their experiences of the world, highlighting the damage caused by ignoring these effects.
How do women's hormones differ from men's in terms of cycling?
Men have one relatively constant hormonal state, primarily testosterone, while women have two cycling hormones, estrogen and progesterone, to manage both sex and pregnancy.

In the second 14 days, progesterone prepares the body for potential pregnancy, optimizing for implantation and pregnancy, which requires different physical and psychological states.
Why do women experience PMS symptoms?
PMS symptoms often arise in the last two weeks of the cycle because the body is gearing up for pregnancy, and ignoring these functional changes can lead to unpleasant experiences.
Why do humans menstruate, unlike most other female mammals?
