BACKGROUND Endocrine-disrupting effects of phthalates are understood primarily from in utero exposures within the fetal rat testis. Nevertheless, their path of action, dose-response character, and cellular target(s) within the fetal testis are not known. OBJECTIVES In this study we investigated the effects of di-(2-ethylhexyl) phthalate (DEHP), mono-(2-ethylhexyl) phthalate (MEHP), and severa...

BACKGROUND Our goals were to describe azithromycin (AZI) pharmacokinetics in maternal plasma (MP), fetal plasma (FP), and amniotic fluid (AF) following intra-amniotic infection (IAI) with Ureaplasma in pregnant rhesus monkeys and to explore concentration-response relationships. METHODS Following intra-amniotic inoculation of Ureaplasma parvum, rhesus monkeys received AZI (12.5 mg/kg every 12 ...

We compared the effects of a single acute dose, or chronic fetal exposure, to 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD) on the male reproductive system of the Wistar(Han) rat. Tissue samples were taken from dams on gestation day (GD)16 and GD21, and from offspring on postnatal days (PND)70 and 120. Steady-state concentration of TCDD was demonstrated in the chronic study: body burdens were comp...

OBJECTIVE To examine whether the concentrations of maternal serum TSH and free thyroxine (fT4) through pregnancy, the presence of thyroid autoimmunity (TAI) or the dose of levo-thyroxine (LT4) replacement can predict the occurrence of maternal or fetal/neonatal complications in pregnant women treated for maternal hypothyroidism. DESIGN The study included 92 women with singleton pregnancies an...

Abstract Study question Can the plasticizer diisopentyl phthalate (DiPeP) disrupt testosterone biosynthesis and alter fetal rat testis histology similarly to other common toxic phthalates? Summary answer DiPeP can dose-dependently suppress mRNA levels of steroidogenic genes induce multinucleated gonocytes in testis, resembling effects phthalates. What is known already an uncommon phthalate, who...
