Short and long-term effects of experimental varicocele.

Background: Varicocele is associated with a progressive decrease in male fertile potential, but it has yet to be determined if the duration of varicocele is associated with altered sperm functional quality.

Objectives: This experimental study investigated the time-dependent effects of varicocele on spermatogenesis, sperm parameters, and sperm functional traits.

Materials And Methods: Thirty-five mature male Wistar rats (200 ± 25 g) were included.

Effects of diabetes-induced hyperglycemia on epigenetic modifications and DNA packaging and methylation during spermatogenesis; A narrative review.

The impact of diabetes on various organs failure including testis has been highlighted during the last decades. If on one hand diabetes-induced hyperglycemia has a key role in induced damages; on the other hand, glucose deprivation plays a key role in inducing male infertility. Indeed, glucose metabolism during spermatogenesis has been highlighted due to post-meiotic germ cells drastic dependence on glucose-derived metabolites, especially lactate.

Insight into inflammation involvement in varicocele: A narrative review.

Background: Varicocele is one of the main causes of male infertility. Although the pathophysiology mechanism of varicocele is very well described and understood, there are some unanswered questions that remains unknown. Some studies have previously described the state of testicular inflammation and sperm in animal models, especially the mouse model, and the seminal plasma of men with varicocele, with or without changes in semen parameters.

Insight toward inflammasome complex contribution to male infertility.

During the last decades, a wide range of factors involved in the physiopathology of male infertility disease have been discussed. The inflammation role in some of the main infertility-related diseases has been studied, such as varicocele, spinal cord injury and obesity. Inflammation is the main response of the immune system to infection or cell damage, leading to intense inflammatory cytokine release during the loss of homeostasis.

Testicular torsion in vivo models: Mechanisms and treatments.

Background: Testicular torsion is a condition in which a testis rotates around its longitudinal axis and twists the spermatic cord. This in turn results in a significant decrease in blood flow and perfusion of testicular tissue. During Testicular torsion, the testicular tissue is affected by ischemia, heat stress, hypoxia, and oxidative and nitrosative stress.
