\r\n\t\tHomozygous mice (minimum age of 8 weeks, maximum age of 14 weeks) are mated for 4-6 weeks. Strains that produce no progeny or pregnant dams after 4 to 6 weeks progress to secondary screening.

\r\n\t\tSecondary Male Infertility Screen:\r\n\t\t\r\n\t\t\t
\r\n\t\t\t\tSet up 2 separate matings: male Hom x female WT or Het\r\n\t\t\t\t\r\n\t\t\t\t\t
\r\n\t\t\t\t\t\tObserve matings for 4 to 6 weeks;
\r\n\t\t\t\t\t
\r\n\t\t\t\t\t\tMatings that result in visibly pregnant females (confirmed by dissection) or pups will be scored MALE FERTILE.
\r\n\t\t\t\t\t
\r\n\t\t\t\t\t\tMatings that do not result in pregnancy will be scored MALE INFERTILITY.
