Аннотация
BACKGROUND: Clinical evidence has shown frequent hypogonadism following mitotane (MTT) treatment in male patients with adrenocortical carcinoma. This study aimed to evaluate the impact of MTT on male gonadal function.
METHODS: Morphological analysis of testes and testosterone assays were performed on adult CD1 MTT-treated and untreated mice. The expression of key genes involved in interstitial and tubular compartments was studied by real-time PCR. Moreover, quantitative and qualitative analysis of spermatozoa was performed.
RESULTS: Several degrees of damage to the testes and a significant testosterone reduction in MTT-treated mice were observed. A significant decline in 3βHsd1 and Insl3 mRNA expression in the interstitial compartment confirmed an impairment of androgen production. Fsh-R mRNA expression was unaffected by MTT, proving that Sertoli cells are not the drug's primary target. Sperm concentrations were significantly lower in MTT-treated animals. Moreover, the drug caused a significant increase in the percentage of spermatozoa with abnormal chromatin structures.
CONCLUSION: MTT negatively affects the male reproductive system, including changes in the morphology of testicular tissue and reductions in sperm concentration and quality.
