ATRAZINE AS AN ENDOCRINE DISRUPTOR AND ITS EFFECTS ON MALE REPRODUCTIVE HEALTH

Abstract

Atrazine has been widely used in Brazilian agriculture, especially in corn and soybean crops. Due to its widespread use, this literature review is relevant to systematize the main studies that evaluate the impact of atrazine as an endocrine disruptor leading to changes in fertility quality, especially in males. In several tests and studies carried out with the exposure of animals to atrazine, negative effects related to changes in factors that are essential for male fertility were observed. Therefore, inhibition of the hypothalamic-pituitary-testicular axis, decreased reproductive cells’s metabolic activity, reduced testosterone levels, reduced lactate dehydrogenase (LDH) enzyme, negative effects on spermatogenesis and morphological changes in the gonads and sperm are results of atrazine toxicity on the male reproductive system that contribute to infertility. In general, it is concluded that atrazine has a potential endocrine disruptor effect, leading to changes in the form of hormone production, especially in hormones related to male sexual reproduction. For this reason, assessing the risks of exposure to this toxin at different stages of life and over several generations, combined with knowledge of its pathophysiological mechanism on the male reproductive system, is essential to preserve the reproductive health of future generations.
