N normal phenotype
behavior/neurological
N
• normal copulatory behavior

cellular
• observed at 2 weeks of age

reproductive system
• bilateral cryptorchism with testes resting high in the abdomen
• the right testicle of some males was in the contralateral position
• lack of tight attachment to the inguinal region and regression of the cranial suspensory ligament
• observed at 2 weeks of age
• absence of postmeiotic cells at 3 months of age
• surgical correction of cryptorchism rescued spermatogenesis, indicating the observed defects may be due to increased the temperature of the abdominal cavity
• the gubernacular bulbs were similar to those wild-type prior to transabdominal descent of the testes (E15.5)
• the gubernacular bulbs are poorly developed relative to wild-type males and resemble those of wild-type females at E17.5
• Mullerian duct derivatives were absent
• male infertility, however female fertility was normal as females produced litters of normal size and exhibited normal oestrus cylces

endocrine/exocrine glands
• bilateral cryptorchism with testes resting high in the abdomen
• the right testicle of some males was in the contralateral position
• lack of tight attachment to the inguinal region and regression of the cranial suspensory ligament

skeleton
• the gubernacular bulbs were similar to those wild-type prior to transabdominal descent of the testes (E15.5)
• the gubernacular bulbs are poorly developed relative to wild-type males and resemble those of wild-type females at E17.5
