Fertility Resultsa
| Percent Fertile | Mean Litter Size | |
|---|---|---|
| WT males | 79 (11/14) | 8.0 ± 0.6 |
| KissCre/Cre males | 56 (5/9) | 7.6 ± 0.9 |
| WT females | 78 (7/9) | 8.3 ± 0.6 |
| KissCre/Cre females | 27 (3/11)b | 4.7 ± 2.0b |
a
Kiss1Cre/Cre animals or their WT littermates were paired with fertile WT mates of the opposite sex for 5 consecutive days, after which the mates were removed. The number of fertile animals is expressed as a percentage of the total number of animals mated per group. Litter size does not include data from animals without offspring.
b
P < .05 by Fisher's exact test for percent fertile and 2-tailed t test for mean litter size.
