The effect of conazoles on reproductive organs structure and function – a review
Conazoles are azole antifungals used in agricultural and pharmaceutical products. Exposure to conazole fungicides leads to several toxic endpoints, including reproductive and endocrine. The results of animal experiments have shown that various conazole fungicides at high doses affect the structure and functions of reproductive organs. In males, adverse effects of conazole fungicides are manifested in the testes, prostate, sperm viability, fertility and sexual behaviour. Reduced testis weight, testis atrophy and reduced or absent sperm production were frequently observed. In female genitalia, structural changes in the ovaries and uterus have been observed. The extent of the changes depends on the dose and duration of treatment. Triazoles affected the expression of multiple genes involved in steroid hormone metabolism and modulate enzyme activity of multiple cytochrome P450 (CYP) and other metabolic enzymes in mammalian liver and other tissues. Conazole fungicides act as endocrine disruptors. Conazoles have been reported to reduce oestradiol and testosterone production and to increase progesterone concentration, indicating the inhibition of enzymes involved in the conversion of progesterone to testosterone. The reproductive effects are consistent with impairment of testosterone homeostasis. The disruption in steroid homeostasis is a common mode of action, leading to abnormal reproductive development and diminished reproductive function. At high doses, azole fungicides affect reproductive organs and fertility in several species.
期刊介绍:
ACTA VETERINARIA BRNO is a scientific journal of the University of Veterinary and Pharmaceutical Sciences in Brno, Czech Republic.
The scientific journal Acta Veterinaria Brno is dedicated to the publication of original research findings and clinical observations in veterinary and biomedical sciences. Original scientific research articles reporting new and substantial contribution to veterinary science and original methods that have not been submitted for publication elsewhere are considered for publication. A written statement to this effect should accompany the manuscript, along with approval for publication by the author´s head of department. The authors bear full responsibility for the contents of their contribution. Book reviews are published, too.
