This article examines the hypothesis that prenatal estrogens contribute to the development of human sexual orientation.
Several groups of women with a history of prenatal exposure to diethylstilbestrol (DES), a nonsteroidal synthetic estrogen, were compared with several samples of control women in the context of a comprehensive study of the psychiatric and psychologic effects of prenatal DES.
Various aspects of sexual orientation were assessed by systematic interview.
Consistently across samples, more DES-exposed women than controls were rated as bisexual or homosexual (scores 2–6 on Kinsey-format scales ranging from 0 to 6).
The data are compatible with the hypothesis that prenatal estrogens may play a role in the development of human sexual orientation.
