Participate in our Research

Psychology Behavior and Sex Hormones Study 

We are currently seeking research participants who have been diagnosed with idiopathic hypogonadotropic hypogonadism (IHH), including Kallmann Syndrome (KS), for an online study regarding hormone replacement therapy and psychological well-being.

To participate, you must be 18 to 65 years old. Although you may wish to participate out of a desire to promote this research, you will also be compensated for your participation (about 45 minutes online) with $25. We would also like relatives of IHH participants (siblings or first cousins) to participate in the study. If you have IHH (including KS) and have a relative who might also be interested in participating, please pass this information on to them. You may still participate even if you do not have a relative who is willing to participate in this study.


Genetics, Personality, and Sexuality

Be part of an important study on the genetics of sexual orientation

  • Have you had your DNA analyzed by 23andMe?
  • Are you 18 years or older?
  • Are you sexually active, or have you been in the past?

If you answered YES to these questions, you are eligible to participate in a study on sexual orientation.
The purpose of this research study is to understand how genetics may influence people’s personalities and sexual orientation. If you take part in this online study, we will instruct you how to find your genetic data file on your 23andMe account and upload it to our secure website. We will also ask you to complete a series of questionnaires on your personality and sexual behavior.
Time required to complete the study should be about 15-25 minutes.
Anyone 18 years or older who has been sexually active and has had a 23andMe analysis is eligible to participate, regardless of sexual orientation.
