2008 journal article

A mixture of five phthalate esters inhibits fetal testicular testosterone production in the sprague-dawley rat in a cumulative, dose-additive manner

TOXICOLOGICAL SCIENCES, 105(1), 153–165.

By: K. Howdeshell*, V. Wilson*, J. Furr*, C. Lambright*, C. Rider n, C. Blystone n, A. Hotchkiss n, L. Gray*

author keywords: androgens; prenatal; reproductive tract; phthalates; cumulative risk; structure activity relationship
MeSH headings : Animals; Body Weight / drug effects; Dibutyl Phthalate / analogs & derivatives; Dibutyl Phthalate / toxicity; Diethylhexyl Phthalate / toxicity; Dose-Response Relationship, Drug; Female; Fetus / drug effects; Logistic Models; Male; Phthalic Acids / toxicity; Pregnancy; Rats; Rats, Sprague-Dawley; Testis / drug effects; Testis / metabolism; Testosterone / biosynthesis
TL;DR: It is demonstrated that individual phthalates with a similar mechanism of action can elicit cumulative, dose additive effects on fetal testosterone production and pregnancy when administered as a mixture. (via Semantic Scholar)

Cumulative effects of dibutyl phthalate and diethylhexyl phthalate on male rat reproductive tract development: Altered fetal steroid hormones and genes

TOXICOLOGICAL SCIENCES, 99(1), 190–202.

By: K. Howdeshell n, J. Furr*, C. Lambright*, C. Rider n, V. Wilson* & L. Gray*

author keywords: endocrine disruptors; developmental toxicity; postnatal; epididymis; RT-PCR; reproductive tract; male; phthalates
MeSH headings : Animals; Animals, Newborn; Cholesterol Side-Chain Cleavage Enzyme / genetics; Cholesterol Side-Chain Cleavage Enzyme / metabolism; Dibutyl Phthalate / toxicity; Diethylhexyl Phthalate / toxicity; Drug Synergism; Drug Therapy, Combination; Female; Fetal Development / drug effects; Gene Expression Regulation, Developmental / drug effects; Genitalia, Male / abnormalities; Genitalia, Male / drug effects; Genitalia, Male / embryology; Humans; Insulin / genetics; Insulin / metabolism; Male; Maternal Exposure; Organ Size / drug effects; Organogenesis / drug effects; Pregnancy; Prenatal Exposure Delayed Effects / chemically induced; Prenatal Exposure Delayed Effects / pathology; Proteins / genetics; Proteins / metabolism; RNA, Messenger / metabolism; Rats; Rats, Sprague-Dawley; Reproduction / drug effects; Testis / drug effects; Testis / embryology; Testis / metabolism; Testosterone / metabolism
TL;DR: The data indicate that individual phthalates with a similar mechanism of action, but with different active metabolites, can elicit dose-additive effects when administered as a mixture. (via Semantic Scholar)

By: K. Howdeshell*, J. Furr*, C. Lambright*, V. Wilson*, B. Ryan n & L. Gray*

author keywords: ethinyl estradiol; bisphenol A; male reproduction; Long Evans rat; testes; epididymal sperm
MeSH headings : Anal Canal / abnormalities; Anal Canal / drug effects; Anal Canal / pathology; Animals; Animals, Newborn; Benzhydryl Compounds; Body Weight / drug effects; Dose-Response Relationship, Drug; Environmental Pollutants / toxicity; Epididymis / drug effects; Epididymis / pathology; Estrogens / toxicity; Ethinyl Estradiol / toxicity; Female; Genitalia, Male / abnormalities; Genitalia, Male / drug effects; Genitalia, Male / pathology; Lactation / drug effects; Male; Maternal Exposure; Organ Size / drug effects; Phenols / toxicity; Pregnancy; Prenatal Exposure Delayed Effects / chemically induced; Prenatal Exposure Delayed Effects / pathology; Rats; Rats, Long-Evans; Seminal Vesicles / drug effects; Seminal Vesicles / pathology; Sperm Count; Spermatozoa / drug effects; Spermatozoa / pathology; Testis / drug effects; Testis / pathology
