The prohibition would be narrower, because it would apply only when children are possible: The Leipzig man whose case brought the issue to attention had a vasectomy in 2004, but that did not affect his criminal liability. And the goal of avoiding genetic abnormalities would justify widening the prohibition to sexual relationships between all couples who are at high risk of having abnormal offspring.
禁令应当收窄，因为只有当可能生育子女的时候才适用：其案件引发关注的莱比锡人2004年就接受了输精管切除术，但这并未影响他承担刑事责任。并且为避免遗传异常有理由将禁令拓宽至诞育异常后代风险较大的所有夫妇。鉴于德国的纳粹史，今天的德国人很难不联想到将决定谁有生育权的权限交给政府。
