Long-term therapeutic effect of cell therapy on improvement in erectile function in a rat model with pelvic neurovascular injury.

Objective: To determine the long-term therapeutic effect amongst three human cell types on erectile function recovery in a rat model of dual neurovascular-injury erectile dysfunction (NVED).

Materials And Methods: A dual NVED model was established in athymic rats by crushing the bilateral cavernous nerves and ligating the bilateral internal pudendal neurovascular bundles. At the time of defect creation, three different types of human cell populations (2.
