Overview

Since 1990, there has been a significant range of published research articles that recognize adverse effects of diethylstilbestrol (DES) in children born to mothers and fathers who were prenatally exposed to DES (i.e. third-generation “DES grandchildren”), as well as extensive studies of the epigenetic effects of endocrine disrupting chemicals.

Studies of DES impact on multiple generations have been substantially strengthened by the continually expanding body of literature emphasizing the human health effects of in utero exposure to endocrine-disrupting chemicals (EDCs) (Pan, 2024; Lite, 2022; Montjean, et al., 2022; Soyer-Goybillard, et al., 2021; Yim, et al., 2021; Rattan & Jodi A. Flaws, 2019; Walker & Gore, 2011). This section will continue to evolve as more related endocrine disruptors and epigenetics research citing DES is identified.

Frequently Listed Effects for Third Generation “DES Grandchildren”

* Increased risk for neurodevelopmental effects, particularly ADHD
* Increased risk for autism spectrum disorders (ASD)
* Increased risk for psychiatric disorders including: schizophrenia, bipolar disorder, behavioral disorders, eating disorders, obsessive-compulsive disorders, violence and addictions, major depression, gender dysphoria
* Increased risk in DES granddaughters of irregular menses and amenorrhea
* Increased risk of genital anomalies (particularly hypospadias and cryptorchidism) in DES grandsons
* Harmful effects on fertility and reproductive development in DES granddaughters
* Increased risk of endometriosis in DES granddaughters
* Increased risk of preterm delivery and possibility of ectopic pregnancy in DES granddaughters
* Cancer risk has not yet been conclusively identified in third-generation females or males
* MRKH Syndrome (congenital aplasia of the uterus and the upper two-thirds of the vagina)
