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 and mRNA expression in the interstitial compartment confirmed an impairment of androgen production. 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.

Fluoride (F), as a natural element found in a wide range of sources such as water and certain foods, has been proven to be beneficial in preventing dental caries, but concerns have been raised regarding its potential deleterious effects on overall health. Sodium fluoride (NaF), another form of F, has the ability to accumulate in reproductive organs and interfere with hormonal regulation and oxidative stress pathways, contributing to reproductive toxicity. While the exact mechanisms of F-induced reproductive toxicity are not fully understood, this review aims to elucidate the mechanisms involved in testicular and ovarian injury.

Background: Over the past five years, the pregnancy rate in assisted reproductive technology (ART) programs in Russia has remained relatively stable. The aim of this study was to assess the distribution of monocyte and macrophage subsets in the blood and follicular fluid of infertile women undergoing assisted reproductive technology.
Methods: The study involved 45 women with a mean age of 35 ± 4.

Hepatitis E Virus (HEV) is a globally widespread pathogen that causes acute hepatitis infection. Beyond hepatic pathogenesis, HEV has been proven to cause several extrahepatic manifestations, such as neurological, renal, and hematological manifestations. It was also associated with mortality in pregnant females.

Hypertension is one of the most common comorbidities in cardiometabolic diseases, affecting nearly one third of adults. As a result, its pathophysiological mechanisms have been studied extensively and are focused around pressure natriuresis, the renin-angiotensin system (RAS), the sympathetic nervous system, oxidative stress, and endothelial dysfunction. Additionally, hypertension secondary to other underlying etiologies also exists.
