Ultrastructural Study of Rat Testis Following Conventional Phototherapy during Neonatal Period.

Introduction: Phototherapy is the most common treatment for neonatal jaundice. This study sought to determine ultrastructural changes in testis, at different time-points, after 48 hours of conventional phototherapy was given to newborn rats.

Methods: Newborn male Wistar rats ( = 36) were divided into two groups as follows - group 1 (G1), control (without phototherapy) and group 2 (G2), exposure to conventional phototherapy for 48 h.
