Summary
Dr Sarah Hill is a professor at TCU, a research psychologist, expert in women’s hormones and brain science, and an author. Each month, women experience hormonal changes that go far beyond the clichés of PMS. These shifts can influence mood, stress response, and even how women relate to others.

Key Moments
How estrogen drives energy and desire in the first half of the cycle
Dr. Sarah Hill explains that rising estrogen in the first half of the menstrual cycle increases energy, sexual desire, and orientation toward social connection, all optimized for the reproductive window around ovulation.
"as because estrogen starts to rise, egg molecules are being stimulated. And as they get stimulated, estrogen gets released and it makes women feel amazing. Right. They generally have more energy. They have higher sexual desire. They have more sex. They're more drawn to men."
Progesterone lowers the brain's threat detection threshold
Dr. Hill describes how progesterone in the luteal phase rewires connections with the amygdala, making the brain's threat detection more sensitive, which contributes to increased anxiety and emotional reactivity during the second half of the cycle.
"progesterone, like the experience of being in the state of this hormone, is one where we tend to be more emotionally So it actually changes the connections with the amygdala in the brain, which is our fear center. And it makes it more interconnected with a greater variety of areas of our brain. And it makes it more sensitive to threat."
Why PMS is a failure of medical science not female biology
Dr. Hill argues that many PMS symptoms stem from medicine treating women as small men and ignoring how hormone cycles shift brain function, disease symptoms, and drug metabolism throughout the month.
"women are a somewhat different version of themselves during the last two weeks of the cycle. Then they are during the first two weeks of the cycle and that a lot of the misery that we experience is the result of t"
