reproductive system
• sperm concentration is (0.94 +/- 1.02) x 106 sperm/ml
• however, testes and seminal vesicle weights are similar to wild-type
• many sperm lack heads and the remainder have abnormal head and/or tail morphology
• dysplasia of the fibrous sheath is frequently observed
• in some cases tail terminate in a coil
• sperm frequently display a short tail
• abnormal hammerhead nuclear shapes are observed
• many sperm lack heads
• some spermatids display abnormal hammerhead nuclear shapes and tail elongation is impaired
• immobile sperm
• sperm fail to fertilize oocytes in in vitro fertilization tests
