Hormones and Behavior Across The Menstrual Cycle
The MSUTR study of Hormones and Behavior across the Menstrual Cycle is an on-going study that will include a total of 590 same-sex female twins between the ages of 16 and 22 years old. This study aims to investigate associations between ovarian hormone levels and several psychological characteristics, including mood, personality, disordered eating, pubertal development, impulsivity and risk taking behaviors. The extent to which genes influence relationships amongst these variables will also be examined.

Famous quotes containing the words hormones, behavior, menstrual and/or cycle:
“Teenage boys, goaded by their surging hormones ... run in packs like the primal horde. They have only a brief season of exhilarating liberty between control by their mothers and control by their wives.”
—Camille Paglia (b. 1947)
“He is not a true man of science who does not bring some sympathy to his studies, and expect to learn something by behavior as well as by application. It is childish to rest in the discovery of mere coincidences, or of partial and extraneous laws. The study of geometry is a petty and idle exercise of the mind, if it is applied to no larger system than the starry one.”
—Henry David Thoreau (1817–1862)
“Virginity is now a mere preamble or waiting room to be got out of as soon as possible; it is without significance. Old age is similarly a waiting room, where you go after life’s over and wait for cancer or a stroke. The years before and after the menstrual years are vestigial: the only meaningful condition left to women is that of fruitfulness.”
—Ursula K. Le Guin (b. 1929)
“Oh, life is a glorious cycle of song,
A medley of extemporanea;
And love is a thing that can never go wrong;
And I am Marie of Roumania.”
—Dorothy Parker (1893–1967)
