From: Selection for female traits of high fertility affects male reproductive performance and alters the testicular transcriptional profile

Mouse line Ctrl FL2
Offspring per litter 11.4 ± 3.3 21.9*** ± 2.6 (192%)
Total litter weight at birth [g] 20.8 ± 4.8 40.4*** ± 4.5 (194%)
  1. Proportions (%) to Ctrl are indicated. Data were tested for normal distribution and analyzed by Student’s t-test (***, p < .0001)
