尊敬的先生，甚至对于年龄超过55岁的夫妻来说双方夫妇不能生育也是非常罕见的。
Your honor, even with respect to couples over the age of 55, it is very rare that both parties to the couple are infertile.
通常来说，不孕不育是个人的隐私，如果一对夫妇不能生育却又渴望生孩子，那确实很不幸。
INFERTILITY is normally seen as a private matter. If a couple are infertile and wish they were not, that is sad.
但在该问题上，没有真正的肇事者（你不能责怪拒绝生育的夫妇），解决方法似乎也很令人鼓舞：鼓励生育，改进学校各项工作，加强科研力度诸如此类。
There are no real culprits (you cannot denounce childless couples) and the solutions sound cheery: encouraging breeding, improving schools, promoting research and the like.
