Atrazine (ATR) is an herbicide that has been shown to have adverse reproductive effects including alterations in levels of pituitary hormones such as prolactin (prl) and luteinizing hormone (LH) in female LE rats when administered at doses of 200 mg/kg/day for 1 and 3 days. Because the action of prl in promotion of progesterone secretion is essential for the initiation of pregnancy in rats, this study was designed to examine the effect of exposure to ATR during early pregnancy on implantation… 

Figures and Tables from this paper

Developmental atrazine exposure suppresses immune function in male, but not female Sprague-Dawley rats.

It is demonstrated that developmental exposure to ATR produced gender-specific changes in immune function in adult rats and suggested that immune changes associated with ATR are not mediated through the suppression of PRL or THs.

The Effect of Atrazine Administered by Gavage or in Diet on the LH Surge and Reproductive Performance in Intact Female Sprague-Dawley and Long Evans Rats

It is indicated that short duration, high-bolus doses of ATR can inhibit the LH surge and reduce the number of follicles ovulated; however, dietary administration has no effect on any endocrine or reproductive outcomes.

Multigeneration Reproduction and Male Developmental Toxicity Studies on Atrazine in Rats

Dietary administration of ATR did not affect rat reproduction up to a parentally toxic dose of 38.7 mg/kg/day, and oral RfDs for ATR would be protective for reproductive effects.

Immunomodulatory effects of maternal atrazine exposure on male Balb/c mice.

Effects of atrazine on sexual maturation in female Japanese quail induced by photostimulation or exogenous gonadotropin

The present results suggest that dietary atrazine exhibits limited reproductive toxicity in female quail during sexual maturation and only at concentrations above ecological relevance.

In Ovo Exposure to a Triazine Herbicide: Effects of Atrazine on Circulating Reproductive Hormones and Gonadal Histology in Young Japanese Quail

Results may suggest that exposure to atrazine in ovo at concentrations above ecologic relevance exerts effects on the reproductive system of young Japanese quail, but no evidence is presented that atrazines induces feminization of the testis in male quail.



Effect of atrazine on ovarian function in the rat.

Chronic effects of atrazine on estrus and mammary tumor formation in female Sprague-Dawley and Fischer 344 rats.

The results support a hypothesis that high-dose atrazine administration in Sprague-Dawley females is related to an acceleration of age-related endocrine changes leading to an earlier onset and/or increased incidence of mammary tumors.

Atrazine disrupts the hypothalamic control of pituitary-ovarian function.

It is demonstrated that atrazine alters LH and prolactin serum levels in the LE and SD female rats by altering the hypothalamic control of these hormones.

Hypothesis for mammary tumorigenesis in Sprague-Dawley rats exposed to certain triazine herbicides.

Longer exposure of Sprague-Dawley females to excessive levels of triazines affects the neuroendocrine system, which in turn alters the pathology of the mammary gland, suggesting changes in neuro endocrine control could result in the expression of an earlier onset and/or an increased incidence of mammary tumors.

Temporal aspects of the regulation of corpus luteum function by luteinizing hormone, prolactin and placental luteotrophin during the first half of pregnancy in the rat.

Intact rats were injected once, subcutaneously, with either 1.0 mg of ergocornine, free base (ECO), to prevent prolactin release, or an equine antiserum to bovine LH (LH-AS), to neutralize endogenous

Teratological evaluations of atrazine technical, a triazine herbicide, in rats and rabbits.

Findings indicated that pregnant rabbits were more than pregnant rats to the effects produced by atrazine technical and the compound was not teratogenic at maternally toxic dose levels in either species.

Prolactin: the initial luteotropic stimulus of pseudopregnancy in the rat.

It is demonstrated that the surges of plasma PRL initiated by cervical stimulation are responsible for transforming a Corpus luteum of the estrous cycle into a corpus lutesum of pseudopregnancy, as reflected by an increase in progesterone secretion of Day 2.

Use of bromoergocryptine in the validation of protocols for the assessment of mechanisms of early pregnancy loss in the rat.

While the pituitary was not identified by these protocols as the site of BEC's primary action, the protocols did identify a reduction in serum progesterone and impaired uterine function as toxicological mechanisms mediating the reduced fertility seen following BEC exposure.
