Most staggerer mutant mice do not mate spontaneously. This deficiency may be attributed to a penile disability (during erection, the penis in extension is directed backward). The main characteristics of this phenomenon and its involvement in the reproduction of the staggerer mutant have been considered in our study. Seventy-four percent (n = 66) of staggerer males presented this temporary abnormality at least once. It appeared when the males were 84 +/- 37-d old (M +/- SD). In most animals the penile abnormality was labile and did not exceed 1 wk duration in 48% (n = 32) of the males. Three males mated in spite of presenting this abnormal erection. Moreover, 25% of males (n = 23) did not present this disability; nevertheless, most of them (91%) still did not reproduce. Other mechanisms are certainly responsible for the inefficient mating. In any case, the influence of penile disability on this deficiency appears to be weak.
大多数蹒跚突变小鼠不会自发交配。这种缺陷可能归因于阴茎功能障碍（勃起时，伸出的阴茎向后弯曲）。我们的研究考虑了这一现象的主要特征及其在蹒跚突变体繁殖中的作用。74%（n = 66）的蹒跚雄性小鼠至少出现过一次这种暂时性异常。这种异常出现在雄性小鼠84±37日龄时（平均值±标准差）。在大多数动物中，阴茎异常是不稳定的，48%（n = 32）的雄性小鼠持续时间不超过1周。有3只雄性小鼠尽管出现了这种异常勃起仍能交配。此外，25%的雄性小鼠（n = 23）没有出现这种功能障碍；然而，它们中的大多数（91%）仍然无法繁殖。其他机制肯定是导致交配效率低下的原因。无论如何，阴茎功能障碍对这种缺陷的影响似乎很微弱。
