Glossary / Lexicon

DES is the abbreviation for Diethylstilbestrol, a powerful estrogen that has been linked to cancer in the reproductive organs of children of women who used the hormone when pregnant.

In the psychology context, DES refers to Diethylstilbestrol, a synthetic estrogen that was prescribed to pregnant women between the 1940s and 1970s to prevent miscarriage and other pregnancy complications. However, it was later discovered that DES caused significant health problems in both the women who took it and their children.

General Description

DES was associated with a range of health issues, including an increased risk of breast cancer, reproductive tract cancers, infertility, and developmental abnormalities in the offspring of women who took the drug. Some of the specific examples of the health problems caused by DES include:

• Clear cell adenocarcinoma: This rare form of cancer affects the cells lining the reproductive organs and is linked to DES exposure in utero.
• Vaginal and cervical abnormalities: Women exposed to DES in utero may have structural abnormalities of the reproductive tract that can increase the risk of infertility, premature birth, and other complications during pregnancy.
• Testicular abnormalities: Men who were exposed to DES in utero may have an increased risk of testicular cancer and other reproductive abnormalities.

Similar Terms

• Teratogen: An agent or factor that causes malformation of an embryo. DES is classified as a human teratogen, underscoring its developmental impact.

• Endocrine Disruptor: A chemical that can interfere with the body's endocrine (hormone) system. DES is a classic example, as it mimics and interferes with natural estrogen.

• Epigenetic Marker: Changes in gene expression (phenotype) that do not involve changes to the underlying DNA sequence (genotype). DES exposure has been linked to potential epigenetic changes that influence later-life health.

• Iatrogenic Illness: Any adverse condition or complication induced unintentionally by a physician or by medical treatment or diagnostic procedures. DES-related health issues are a well-documented example of iatrogenic harm.

• Intergenerational Trauma: The transmission of trauma or distress across generations. In the DES context, this involves mothers feeling guilt or anxiety, which is then absorbed or reflected by their children facing health challenges.

Summary

DES (Diethylstilbestrol) is a synthetic estrogen historically prescribed to pregnant women (1940s-1970s) for complication prevention, but it subsequently became a major focus in psychology and medicine due to its long-term adverse health and psychological effects on both the mothers and their offspring (known as DES-exposed individuals or DES Daughters/Sons). Medically, it is associated with reproductive cancers (e.g., clear cell adenocarcinoma) and structural abnormalities. In psychology, DES-related research often examines the psychosocial impact of these delayed health risks, including heightened anxiety, fertility-related stress, body image issues related to reproductive tract surgeries, and the complex intergenerational trauma and identity formation associated with being a "drug-affected" cohort. Understanding the psychological toll is crucial for providing targeted therapeutic support.
