An ectopic
testicle descends normally through the
inguinal canal but then moves into an abnormal
position in the
groin area.
Locations for ectopic testicles include:
- The superficial inguinal pouch, which is a small
pocket under the skin of the groin just below the inguinal canal. This is the
most common location for an ectopic testicle.
- The femoral canal
(the inner portion of the thigh near the groin).
- The perineum
(below the scrotum).
- The suprapubic region (above the
penis).
- In the scrotum on the opposite side (contralateral). This
is the least common type.
Ectopic testicles are likely related to abnormalities of the
gubernaculum, which is a fibrous, cord-like membrane that runs through the
inguinal canal from the abdomen to the scrotum. The gubernaculum helps to guide
the descent of the testicles and has branches that attach to these other
locations. Ectopic testicles usually will not descend into the normal position
in the scrotum on their own.
Most ectopic testicles can be felt (are palpable) during a physical
examination by a doctor. However, surgery may also be required to distinguish
between an ectopic testicle and a true undescended testicle.
Doctors recommend surgical treatment to place an ectopic testicle in
its normal position any time after about age 6 months but no later than 2 years
of age.
