Evaluation of human bone marrow mesenchymal stem cells in the treatment of non obstructive azoospermia.

Background: Non-obstructive azoospermia (NOA) represents an infertility problem that is usually difficult to treat. Such patients usually have testicular biopsy of germ cell aplasia or spermatogenic arrest. In recent decades, mesenchymal stem cells (MSCs) had been studied thoroughly and proved safe and effective regarding their capability for trans-differentiation into different cell types.
