What Is Allostasis?

Allogeneic testis transplantation is an ideal method for the treatment of hypo testosterone caused by lack of testicles, bilateral small testicles, or severe testicular atrophy, so that patients can relieve trauma and enhance life confidence. However, the spermatogenic function is not ideal after surgery. Once the rejection occurs, whether it is acute or chronic rejection can lead to the loss of spermatogenic function in the transplanted testes.
