Introduction and Disclaimer


Because we know it's impossible for one organization to be everything to everyone, we've provided information here about other organizations and support groups for individuals with X&Y Chromosome variations and their families. Note that entries listed under "Organizations" often also include information about additional support groups.

Check out other resources on this website. AXYS supports multiple forums for individuals with X&Y chromosome variations and their families. Also, be sure to also look in our library for articles regarding X&Y Chromosome variations as well as articles on subjects affecting individuals with X&Y chromosome variations.

Note that AXYS provides these resources with the understanding that each has its own viewpoints, methods, and messages.  In many cases, information they provide may conflict with information AXYS provides.  We respect their independence, but being listed here does not constitute and endorsement.  A disparity of viewpoints reflects the fact that the science is evolving and different groups may interpret evidence differently.  In all cases, we urge you to consult with your medical professional(s) and use your best judgment to consider all the facts and opinions presented by AXYS and other organizations.

Sex Development: An Overview

KS&A celebrates the diversity of the human family; including sex and gender, skin color, ethnicity, religion, sexual orientation, gender identity, age, socioeconomic status, physical characteristics, and mental abilities.  While the majority of 47,XXY individuals we serve identify as male, a minority identifies as “intersex” or another gender.  Many also consider themselves as “being XXY” rather than “having XXY.”  
The organizations listed below are separate from KS&A and each has a unique mission focused on intersex.  KS&A respects these organizations, but we also recognize that some of their positions and interpretations of information may not align with KS&A's.
If you are reading this page, perhaps you have questions about gender identity.  If so, we encourage you to explore gender counseling.
