Signs and symptoms of a retractile testicle include:
If your son has a retractile testicle, the testicle originally descended as it should, but doesn't remain in place. If this descent isn't completed at birth, the testicle usually descends within a few months. During the final months of development, the testicles gradually descend into the scrotum. Testicles form in the abdomen during fetal development.
