[1] The positions of the ectopic testis may be: in the lower part of the abdomen, front of the thigh, femoral canal, skin of the penis, or behind the scrotum.
[1] The ectopic testis is initially normal, but if it is ignored after childhood, it may become small and soft, with spermatogenesis arresting and interstitial cell proliferation occurring.
[4] Ectopic testes are prone to malignancy, epididymo-orchitis, infertility, testicular torsion, and trauma.
[6] It could be caused by local mechanical barriers obstructing the normal descent, aberrant gubernacular stabilization as a result of an anomaly at its distal end, or aberrant interaction between androgen and calcitonin gene-related peptide (CGRP).
[7][8] Diagnosis can be made based on the presence of an empty scrotum and swelling in the perineal area.
