Milton Diamond Archives - Diethylstilbestrol DES

Several published studies in the medical literature on psycho-neuro-endocrinology have examined the hypothesis that prenatal exposure to estrogens (including Diethylstilbestrol) may cause significant developmental impact on sexual differentiation of the brain and on subsequent behavioural and gender identity development in exposed males and females. There is significant evidence linking prenatal hormonal influences on gender identity and transsexual development.

Gender identity and Diethylstilbestrol DES exposure image — There is a possible connection between DES exposure and gender variance

In 1999, Dr. Scott Kerlin (founder of the DES Sons International Network) began researching the effects of Di-Ethyl Stilbestrol® on the health of genetic males who had been exposed prenatally. A substantial amount of research had been done on women who had been exposed but relatively little had been done on men and DES sons. When it became apparent that a significant portion of his research group were either transsexual, transgendered or intersexed, he began to explore the possibility of a connection between prenatal DES exposure and gender variance. Dr. Kerlin is not the first researcher to note a correlation between DES exposure and feminized behaviour in genetic males; studies go back as far as 1973. However, Dr. Kerlin has delved much deeper than those who came before.

Radio Interview: DES Exposure and Gender Variance

Listen to KWMR Radio Interview with Dr. Dana Beyer on the side effects of Diethylstilbestrol and its influence on gender identity

Dr. Dana Beyer is the medical advisor and web manager of the DES Sons International Network, on the effects of endocrine disrupting compounds such as Diethylstilbestrol, DDT, phthalates and bisphenol A, on human sexuality and reproduction, as well as providing personal support and mentoring. In 2005 she presented a breakthrough paper, with her colleagues Dr. Scott Kerlin and Dr. Milton Diamond, to the International Behavioural Development Symposium, delineating the impact Di-Ethyl Stilbestrol® has had in causing intersex and gender variations in human beings.

I understand this is a sensitive and controversial matter but I feel it is important to bring this issue to light and break the wall of silence around what is still nowadays considered as “taboo”. I would like to invite all DES exposed individuals who have a knowledge of DES exposure and gender identity either through research or personal experience to share their comments and stories.
