Table 1. Testicular Functional Parameters in Nf1^+/+ and Nf1^+/- mice.

Values listed in each column are mean ± SEM. Bold numbers indicate p≤ 0.05 and are considered to be statistically significant.

Average Litter Size	8.67 ± 0.76	4.00 ± 1.2	0.007
Days between Litters	33.4 ± 4.7	31.2 ± 4.9	0.75
Sperm Count (x106 spermatozoa/ml)	8.8 ± 5.5	15 ± 2.3	0.02
