scrotum (empty)

Last reviewed 01/2018

Causes of an empty scrotum include:

  • maldescended testes
  • retractile testes
  • testicular atrophy (trauma, mumps, Klinefelter's syndrome, Kalman's syndrome, Noonan's syndrome)
  • ambiguous genitalia
  • testicular agenesis - accounts for about 5% of testes that are not palpable

The scrotum is hypoplastic if it has never contained a testis.
