This is an open label, single arm, single center investigation to assess the safety and efficacy of purified adult autologous bone marrow derived CD34+, CD133+, and mesenchymal stem cells injected into the seminiferous tubules and testis, through a 12 week follow-up period. The investigators' selected model of research is based on maximizing the efficiency of the approach by choosing an autologous pattern which preserves the genetic make-up of an individual that is vital in infertility conditions. Additionally the approach involves injecting a combination of different but purified cell types which all aid in the retrieval of spermatogenesis, and the generation of mature spermatozoa. Expected outcomes of this study are defined in general improvements in infertile patients in regards of testicular morphology, sexual function, semen quality, development of primary or secondary spermatocytes, spermatids, or mature spermatozoa in the testis, seminiferous tubules, or semen.

Appearance of different germ cells in testicles through the progress of spermatogenesis will be assessed by the count of cells using histological studies.
