Abstract (original English)
Background & objective Spermatogenesis is a temperature-dependent process, and testicular heat stress can cause spermatogenic failure by inducing cell apoptosis and oxidative stress, ultimately leading to male infertility. Adipose-derived mesenchymal stem cells (AMSCs) have been considered an effective therapy for various tissue degenerations, demonstrating the ability to stimulate testicular regeneration and restore spermatogenesis. The current study focuses on the therapeutic potential of AMSCs on semen quality, testicular morphological changes, and oxidative stress parameters in rats exposed to heat stress. Methods In this experimental study, 35 adult male rats were randomly assigned to five groups: Group I (control), Group II (vehicle), Group III (heat stress group, temperature-humidity index: 43 °C for 20 minutes), and Groups IV and V (treatment groups receiving 0.5×10⁶ and 1×10⁶ AMSCs, respectively, on the second and fifteenth days after heat stress induction). Sixty days after heat stress exposure, the animals were euthanized; serum testosterone levels and oxidative stress biomarkers were analyzed, and the testes and epididymis were collected for histological and sperm evaluation. Results Scrotal heat stress caused deleterious effects on testicular histological structure and function. Testosterone levels and total antioxidant capacity were significantly reduced in the he
