  • Mean sperm density was significantly decreased between control, unilateral and bilateral cryptorchid samples (110 vs. 80 vs. 16 million/cc, p = 0.05).

  • An apoptotic gene (TNF-alpha induced protein 3) was highly over-expressed (p = 0.001) in the cryptorchid samples suggesting a role for apoptosis as a cause for poor sperm densities.
