The regenerative properties of p-tyrosol were investigated in a model of testicular insufficiency caused by a toxic effect on spermatogonial stem cells (single administration of paclitaxel in the maximum tolerable dose). Against the background of p-tyrosol administration, we observed an increase in the number of normal spermatogonia and Sertoli cells, stimulation of spermatogenesis, and renewal of the spermatogenic tissue. The treatment with p-tyrosol also led to a decrease in DNA damage in cells of the testicular tissue. These changes were accompanied by a decrease in the level of free radicals, an increase in antioxidant protection, and normalization of the redox potential.

Background: Non-obstructive azoospermia (NOA), the severe type of male infertility. The objective of this study was to evaluate the predictive accuracy of a prediction model of sperm retrieval failure with fine needle aspiration (FNA).
Methods: This study involved 769 NOA patients (dataset 1) undertaking FNA and 140 NOA patients undertaking mTESE (dataset 2).

Huntington's disease (HD) is a debilitating neurodegenerative disorder characterized by severe motor deficits, cognitive decline and psychiatric disturbances. An early and significant morphological hallmark of HD is the activation of astrocytes triggered by mutant huntingtin, leading to the release of inflammatory mediators. Fingolimod (FTY), an FDA-approved sphingosine-1-phosphate (S1P) receptor agonist is used to treat multiple sclerosis (MS), a neuroinflammatory disease, and has shown therapeutic promise in other neurological conditions.

Background: 95% of men with spinal cord injuries exhibit difficulties with sexual function, including erectile dysfunction, anejaculation, retrograde ejaculation, poor ejaculatory force, and poor sperm quality.
Aim: The primary goal is to determine if well-established interventions, such as spinal cord epidural stimulation, are a feasible treatment for sexual dysfunction and if locomotor recovery training can be used to improve ejaculatory function in a rodent model of spinal cord injury (SCI).
Methods: Male Wistar rats underwent thoracic laminectomies (shams), spinal cord transections, or moderate spinal cord contusion injuries.

Prospermatogonia (ProSGs), the progenitors of spermatogonial stem cells in neonatal testes, undergo critical migration to the testicular microenvironment-a fundamental process for testicular development and subsequent spermatogenic capacity. The SDF-1/CXCR4 chemokine axis serves as an essential molecular guidance mechanism, directing ProSGs toward the basal membrane of seminiferous tubules. Nevertheless, the precise molecular mechanisms governing this axis remain incompletely understood.
