Abstract

Production of adrenal steroid hormones in pubertal male Wistar rats exposed to low doses of DDT during both prenatal and postnatal and only postnatal development has been investigated. Rats exposed to the disruptor prenatally and postnatally, and only postnatally were characterized by opposite changes in production of mineralocorticoids, glucocorticoids, male and female sex hormones. The study revealed that daily exposure to low doses of DDT enhanced conversion of progesterone to 17-OH-progesterone and did not exert selective antiandrogenic or proestrogenic action typical for the effect of toxic and subtoxic doses. In rats, exposed to DDT during their prenatal and postnatal development, impaired morphogenesis of the adrenal cortex and circulatory disorders in zona glomerulosa contributed to reduced aldosterone and sex steroid hormones production.
