Measures of testis function

	Testis / body weight (%)	Plugged female **	Pregnant female	litter size (Ave.)
Gm114+/+	0.23 (n=5)	16	13	9.1
Gm114−/−	0.24 (n=4) *	15	11	8.9

^*P=0.7724, no significant difference between the mutants and wild type adult mice;

^**5 wild type and 5 mutant adult male mice at 6 and 16 months of age. Each male mouse was set up in continuous mating with 3 wild type female mice. Mating statistics and fertility were also unaffected.
