Testicular inflammation in male reproductive system

The control of the immune system, neuroendocrine system, and energy metabolism is essential for the physiological process of male reproduction. The hypothalamic-pituitary-testicular (HPT) axis regulates the generation of gonadal steroid hormones in the testes, which in turn controls spermatogenesis. For the growth and maturation of germ cells, the immune cells and cytokines in the testes offer a safe microenvironment. The cellular reactions and metabolic activities in the testes produce energy and biosynthetic precursors that control the growth of germ cells, as well as testicular immunology and inflammation. Both inflammatory and anti-inflammatory responses depend on immune cell metabolism, which is thought to influence testicular spermatogenesis. The significance of immunometabolism in male reproduction will be underlined in this review.
