The Pacific Center for Sex and Society (PCSS) , whose director is Dr. Milton Diamond, is located within the University of Hawai‘i. It is a not-for-profit entity associated with the John A. Burns School of Medicine (Department of Anatomy, Biochemistry and Physiology).

Research at the Center is primarily concerned with sexual development and other issues of sex that are related to social issues. We have done research on and published on such topics as abortion, family planning, HIV/AIDS, homosexuality, intersexuality, pornography, same-sex marriage, transsexuality and sex education.

A wide range of published papers is archived on this web site; these mainly address issues of intersex, transgender, transsexuality, ethics and pornography. Visitors are very welcome to read them, whether their interest is professional or personal.

We regret to announce that the Center's Director, Dr. Milton Diamond, died on March 20, 2024 at the age of 90.

His obituary is available here and may be freely used by the media.
