Infertility is a serious medical, economic, and psychological problem in the society. Male factor infertility, due to defective spermatogenesis as a result of a failure in germ cell proliferation and differentiation, appears to be the cause of 25-50% of infertility cases. According to several surveys, testicular degeneration can be caused by a variety of physical, chemical, and microbial causes. A stem cell is a non-specialized cell which is characterized by self-renewal by mitotic cell division and able to differentiate to specialized cells for the various tissues of the body. The data were obtained and analyzed from different databases (PubMed, Google Scholar, Egyptian Knowledge Bank, Elsevier, Medline, Embase, ProQuest, and BMC). This review discusses the causes, symptoms, and grades of testicular degeneration and the use of different types of stem cells in regeneration. And its conclusion based on previous researches and trials, MSCs are considered effective therapy for testicular degeneration. |
