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)
“If you are willing to inconvenience yourself in the name of discipline, the battle is half over. Leave Grandma’s early if the children are acting impossible. Depart the ballpark in the sixth inning if you’ve warned the kids and their behavior is still poor. If we do something like this once, our kids will remember it for a long time.”
—Fred G. Gosman (20th century)
“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)
“The cycle of the machine is now coming to an end. Man has learned much in the hard discipline and the shrewd, unflinching grasp of practical possibilities that the machine has provided in the last three centuries: but we can no more continue to live in the world of the machine than we could live successfully on the barren surface of the moon.”
—Lewis Mumford (1895–1990)
