Mounting behavior of ArKO and wild-type male mice
| Mice | No. of mounts/ 20 min | Time to first mount, min | Mount latency, min |
|---|---|---|---|
| Wild type | 11 ± 1.9 | 4.41 ± 1.3 | 1.37 ± 0.02 |
| ArKO | 0 | — | — |
Sexual behavior appeared normal in the wild-type male animals at age 12–14 weeks. In contrast, ArKO mice demonstrated severely impaired mounting behavior (K. M. Robertson and M. E. E. Jones, personal communication).
