Hormones &
Mood Study






  Thanks for taking the time to learn more about the Hormones & Mood (HAM) Study.

  We are currently recruiting healthy volunteers to participate in the study.

  • The HAM study is a scientific research study that examines mood and hormonal responses to naltrexone,
     an FDA approved drug that is generally utilized in the treatment of opioid and alcohol dependence.
  • We are interested in how naturally occurring levels of certain hormones, such as estrogen, progesterone, or      testosterone may affect response to this drug. Therefore, we are studying healthy women at various stages in      their menstrual cycle, as well as healthy men.

  • The study involves participation in two laboratory sessions over one to two months at the Clinical Addictions
     Research Laboratory at the University of Chicago.

  • Please take a moment to learn more about the study by using the buttons at the top of the page.
