Mouse lines carrying:
Amh^tm1Bhr mutation (2 available); any Amh mutation (24 available)

♀	phenotype observed in females
♂	phenotype observed in males
N	normal phenotype

endocrine/exocrine glands

increased Leydig cell number ( J:21396 )

• focal hyperplasia in 27% of males 10 weeks or older

• in spite of the hyperplasia, the cells were functionally normal

• one neoplasm containing multiple foci of leydig cell hyperplasia was detected

reproductive system

reproductive system phenotype ( J:21396 )

N	• XX females were fertile and displayed normal uteri containing morphologically normal oviducts

increased Leydig cell number ( J:21396 )

• focal hyperplasia in 27% of males 10 weeks or older

• in spite of the hyperplasia, the cells were functionally normal

• one neoplasm containing multiple foci of leydig cell hyperplasia was detected

male pseudohermaphroditism ( J:21396 )

• XY male mice developed hypoplastic female structures derived from the Mullerian duct, namely a uterus, uncoiled oviducts, and a vagina

• uterine horns paralleled the vas deferens and joined to form cervix that opened into a vagina

• the physical association of the uterine horns with the vas deferens caused the horns to be pulled caudally

• XY males displayed normal sized testes that were fully descended and spermatogenesis was unimpaired

• proper differentiation of the Wolffian duct system

secondary sex reversal ( J:21396 )

reduced male fertility ( J:21396 )

• 13% of males were able to impregnate wild-type females

• infertility putatively due to a blockage of sperm movement resulting in a diversion from the normal pathway
